Why is my label printer skipping labels or shifting the print?
Explore preventive maintenance
Scheduled visits to check, clean and adjust your printers and spot worn parts before they fail.
In brief. When a printer skips labels or prints out of position, it can no longer find the start of each label: the gap, notch or black mark that separates them. Manufacturers' documentation first cites a calibration that needs redoing for the loaded media, then a sensor that is dirty or covered by a label, a media type set incorrectly and a sensor in the wrong position. Run a calibration again after every label change; if the skipping continues, clean the sensor and check its position.

Why does a label printer skip labels? The causes cited by manufacturers
These causes come from the manufacturers' guides, from the most often cited to the rarest; each example names the model concerned, whose entry in the by-model table below gives the exact procedure.
- Printer not calibrated for the mediaCalibration teaches the printer the media type and the label length. Zebra calls for it every time the media size or type changes, and as soon as the printer skips labels (ZT410, ZT421). Brother specifies it at every media change (TJ-4420TN), and Honeywell also after a firmware update (RP4).
- Sensor dirty or covered by a labelDust, adhesive or a label that has come loose prevent the sensor from seeing the gap or the mark. Sato cites this for errors 1028 (
Gap Not Found) and 1035 (I-mark Not Found) on the CT4-LX, Honeywell for a PC42t that feeds labels without stopping, and GoDEX and Brother among the causes of skipped labels (GE300, TD-4). - Media type or sensor type set incorrectlyThe printer must know whether the media has gaps, has black marks or is continuous. Zebra describes separate labels being treated as continuous media by a printer set to continuous or not calibrated (ZT410, ZT510); Sato has you choose [Gap] or [I-Mark] in the [Sensor Type] setting (CL4NX). On the ZQ510, the black mark sensor is used by default: according to Zebra, gap media generally requires a setting change.
- Sensor in the wrong positionThe sensor must be opposite the gap, notch or black mark. Zebra leaves the movable sensor in the centre for gap labels and otherwise aligns it with the mark or notch (ZD420, ZD620); Toshiba places the black mark sensor at the centre of the mark (B-EX6) and Honeywell aligns the stop sensor with the black marks (PD43).
- Media loaded incorrectly or guides badly positionedMedia that wanders from side to side instead of feeding straight upsets detection: Sato cites this for errors 1028 and 1035 (FX3-LX, PW208NX). Zebra asks for guides that just touch the edge of the media (ZT421), and GoDEX cites the adjustment of the paper guides (G500).
- Label format or length set incorrectlyZebra cites an incorrect label format (ZT610) and, on the ZQ620 Plus, a maximum label length (Label Length Max) that is too short: the printer then assumes the media is continuous. GoDEX blames the label height setting (EZ6250i). Honeywell explains every other label being skipped by content placed too close to the top edge (MP Nova).
What to check, in order
- Reload the mediaRoll properly seated, media fed through the sensor, guides touching the edge: according to Sato, the media must feed straight.
- Clean the sensorRemove any stuck label, then the dust: Zebra recommends canned air or a dry cotton swab, and a swab moistened with alcohol for adhesive (GK420, ZD411).
- Position the sensor and set the media typeThe sensor must be opposite the gap, notch or black mark. Then, in the menus, set the type of media actually loaded: gap, black mark or continuous.
- Run a calibrationFor example, PAUSE and CANCEL held for two seconds on the Zebra ZD411 or ZD620 (SmartCal calibration), [Auto-calibration] on Sato printers, the Print button held down on the Honeywell PC42t and PD45S. Then press FEED: according to Zebra, a single label should advance. If automatic calibration fails, move on to the manual calibration in your model's guide.
- Check the label format and lengthThe label size set in the software or driver must match the media: Zebra points out that they can override the printer's settings (ZT410). On the ZQ610 Plus and ZQ620 Plus, set Label Length Max at least 25.4 mm above the label length, gap included.
- Call in a technician if the skipping continuesFirst clean or replace the platen roller if it slips (Zebra ZD410, ZD620). Honeywell then mentions a faulty media sensor and refers you to service (MP Nova, RP4); Sato refers you to its dealer or its technical support (CL4NX, PW4NX).
Caution: Let the printhead cool before opening the printer: Zebra warns that it can cause severe burns. Remove rings, watches and other metal objects before working near the printhead (Zebra), and keep your hands away from moving parts during calibration (Toshiba). To remove dust from the sensors, Zebra forbids the use of an air compressor; do not use any hard or pointed tool to remove a stuck label (Honeywell).
What the documentation recommends, model by model
For 61 models, the manufacturer's documentation describes this symptom. Each row links to the detailed entry in the guide, with the full procedure and its sources.
| Model | Guide entry | Short answer |
|---|---|---|
| Zebra ZT230 | Why is my Zebra ZT230 skipping labels and how do I calibrate it? | The printer is no longer calibrated for the media and ribbon installed. Run the manual sensor calibration: hold PAUSE + CANCEL for 2 seconds (or, on the ZT230, the TOOLS > SENSORS > START menu), then follow the procedure below. |
| Honeywell PF4i | Why does my Honeywell PF4i feed labels abnormally? | According to the Intermec guide, the characteristics of the media may have changed: press the Print button to run the feed adjustment again. Then check the Label rest dots and Media Type parameters and the position of the LSS, and clean the media guides. |
| Zebra ZT410 | How do I calibrate a Zebra ZT410 that skips labels? | With the printer ready, press and hold PAUSE and CANCEL for 2 seconds. Open the printhead, leave only the backing between the sensors, remove the ribbon, close and press PAUSE. Then place a label back under the sensors, reload the ribbon, close and press PAUSE again. |
| Zebra ZT410 | Why does auto calibration fail on my Zebra ZT410? | According to Zebra, the media or ribbon is incorrectly loaded, the sensors do not detect the media or ribbon, the sensors are dirty or incorrectly positioned, or the media type is set incorrectly. Reload, clean and reposition the sensors, check MEDIA TYPE, then do a manual calibration. |
| Toshiba B-852 | How do I calibrate my Toshiba B-852 (threshold setting) when it does not detect the start of pre-printed labels properly? | With pre-printed labels, the ink can mislead the gap sensor; with black marks on the back, the reflection of the paper can vary. Toshiba then provides for manual threshold setting: in pause, hold PAUSE for 3 seconds, choose the sensor, then hold PAUSE while the printer feeds at least 1.5 labels. |
| Toshiba B-852 | How do I adjust the sensor position (gap or black mark) on my Toshiba B-852? | With the printhead raised, turn the green sensor adjustment knob to place its arrow in the centre of the label (gap sensor), or the black mark indicator opposite the mark. According to Toshiba, a properly centred sensor detects the gaps reliably, even with round labels. |
| Zebra ZT421 | How do I calibrate my Zebra ZT421 when labels are skipped or the print shifts? | Touch Menu > Print > Sensors > Manual Calibration, then Start Calibration, and follow the on-screen prompts exactly. At the end, press PAUSE to exit pause mode. Zebra recommends this calibration whenever you change the type or size of ribbon or media. |
| Zebra ZT421 | Why does auto calibration fail on my Zebra ZT421 (“Auto Calibrate failed”)? | Zebra cites incorrectly loaded media or ribbon, sensors that do not detect the media or ribbon, dirty or incorrectly positioned sensors, and an incorrectly set media type. Reload the media and ribbon, clean and reposition the sensors, choose the correct media type, then run a manual calibration. |
| Zebra ZT420 | How do I calibrate a Zebra ZT420 that skips labels? | With the printer ready, press and hold PAUSE and CANCEL for 2 seconds. Open the printhead, leave only the backing between the sensors, remove the ribbon, close and press PAUSE. Then place a label back under the sensors, reload the ribbon, close and press PAUSE again. |
| Zebra ZT420 | Why does auto calibration fail on my Zebra ZT420? | According to Zebra, the media or ribbon is incorrectly loaded, the sensors do not detect the media or ribbon, the sensors are dirty or incorrectly positioned, or the media type is set incorrectly. Reload, clean and reposition the sensors, check MEDIA TYPE, then do a manual calibration. |
| Zebra ZT411 | How do I calibrate my Zebra ZT411 when labels are skipped or the print shifts? | Touch Menu > Print > Sensors > Manual Calibration, then Start Calibration, and follow the on-screen prompts exactly. At the end, press PAUSE to exit pause mode. Zebra recommends this calibration whenever you change the type or size of ribbon or media. |
| Zebra ZT411 | Why does auto calibration fail on my Zebra ZT411 (“Auto Calibrate failed”)? | Zebra cites incorrectly loaded media or ribbon, sensors that do not detect the media or ribbon, dirty or incorrectly positioned sensors, and an incorrectly set media type. Reload the media and ribbon, clean and reposition the sensors, choose the correct media type, then run a manual calibration. |
| Honeywell PX6i | How do I calibrate a Honeywell PX6i (testfeed)? | On the PX6i, calibration is done with a testfeed: press Feed and Shift simultaneously. The printer feeds a blank label and adjusts the media feed. The guide requires it after a change of media type or when the media does not feed correctly. |
| Toshiba B-EX4T1 | How do I calibrate my Toshiba B-EX4T1 (threshold setting) when it does not detect the start of the labels properly? | First place the sensor in the centre of the labels, or in the centre of the black mark. If the start is still detected incorrectly, set the threshold: in pause, hold PAUSE for 3 seconds, choose the reflective or transmissive sensor, then hold PAUSE while the printer feeds at least 1.5 labels. The OK (Mid.) result is optimal; confirm with ENTER. |
| Toshiba B-EX4T1 | How do I enable automatic calibration on my Toshiba B-EX4T1? | The calibration type is chosen in the initial setup wizard (CALIBRATE screen: OFF, LABEL/GAP or BLACK MARK), which appears at first start-up and after the parameters have been cleared. After that, the CALIBRATE parameter is in the SET PARAMETERS menu of user system mode. |
| Zebra S4M | How do I calibrate a Zebra S4M? | If automatic calibration is enabled in the control panel, the S4M calibrates at power-on and each time the printhead is closed: it measures the label length and sets its sensors. After a change of label or ribbon type, Zebra also recommends a manual calibration of the media and ribbon sensors. |
| Zebra S4M | Why does my Zebra S4M skip labels or fail to detect the gap between labels? | The sensor does not correctly locate the start of the labels: media type set incorrectly, unsuitable sensor or reflective sensor badly positioned. Set MEDIA TYPE and SENSOR SELECT, align the sensor with the gap, notch or black mark, then recalibrate. |
| Zebra GK420 | How do I calibrate my Zebra GK420 when it skips labels or does not print at the top of the label? | With the printer switched on, the cover closed and the light solid green, hold down FEED and release it during the sequence of two green flashes. The GK420 detects the media type and length, adjusts its sensors and feeds one to four labels. |
| Zebra GK420 | How do I perform a manual calibration on my Zebra GK420 with pre-printed labels? | With media loaded and the printer switched on, hold down FEED until the sequence of seven green flashes, then release it. The GK420 adjusts its sensor, prints a sensor profile and saves the new settings. |
| Zebra ZD421 | How do I calibrate my Zebra ZD421 with SmartCal after changing labels? | Load the media (and the ribbon in thermal transfer mode), close the cover and wait until the STATUS light is solid green. Then press and hold PAUSE and CANCEL together for two seconds: the printer feeds and measures a few labels, then STATUS returns to solid green. |
| Zebra ZD421 | Why does my Zebra ZD421 skip labels or print out of position? | Zebra first cites incorrectly loaded media or a badly positioned movable sensor, then sensors not calibrated for the media. Check the loading and the sensor position, run a SmartCal calibration; if the problem persists, clean or replace the platen roller. |
| Sato FX3-LX | What does “Error 1028 (Gap Not Found)” or “Error 1035 (I-mark Not Found)” mean on my Sato FX3-LX? | The printer cannot find the gap between labels (1028) or the black mark (1035). Reload the roll so that it feeds straight, clean the sensor, check the sensor type ([Gap] or [I-Mark]) and then run the calibration again. |
| Sato FX3-LX | How do I calibrate the label sensor on my Sato FX3-LX? | First choose the sensor type ([Gap] or [I-Mark]) in [Printing] > [Sensor Type], then run the automatic calibration in [Printing] > [Calibrate], with only the liner (no label) placed over the sensor and the cover closed. Then check the feed with [FEED]. |
| Zebra GX420 | How do I calibrate my Zebra GX420 when it skips labels? | With the printer switched on and the cover closed, hold down FEED and release it during the sequence of two green flashes. The GX420 detects the media type and length, adjusts its sensors and feeds one to four labels. |
| Zebra GX420 | How do I perform a manual calibration on my Zebra GX420 with pre-printed media? | With media loaded and the printer switched on, hold down FEED until the sequence of seven green flashes, then release it. The GX420 adjusts its sensor, prints a sensor profile and saves the settings; then press FEED: one whole blank label should come out. |
| Zebra QLn420 | How do I calibrate my Zebra QLn420 when it skips labels? | Zebra links skipped labels to three causes: media with no detectable black mark or gap, print area exceeded, black mark or gap sensor blocked or faulty. Check the media and the media type setting, clean the sensor windows, then check the calibration settings in the QLn420 menus. |
| Godex MX20 | How do I calibrate my Godex MX20 when it skips labels or stops in the wrong place? | Switch off the printer, then switch it back on while holding down the FEED button. After two beeps, the MX20 measures the labels, stores their height and prints a self-test label. |
| Godex MX20 | Why does my Godex MX20 skip labels while printing? | The GoDEX manual cites three causes: an incorrect label height setting, dust on the sensor, or automatic detection that needs to be run again. Check the label height, clean the sensor, then run the calibration again. |
| Zebra ZQ630 | How do I calibrate a Zebra ZQ630? | Label length calibration is started from the Tools menu, with the “Label Length Cal” function. If it fails, the Label Length Max setting is probably too low: the printer then thinks the media is continuous. |
| Zebra ZQ630 | Why is my Zebra ZQ630 skipping labels? | According to Zebra, the printer is not correctly locating the start of the labels. Check that the media has gaps or black marks, that the format does not exceed the print area and that the sensors are not blocked, then recalibrate. |
| Zebra ZQ511 | Why is my Zebra ZQ511 not detecting black marks or skipping labels? | Check the position of the black marks: they must be centred on the roll, and on the back of the media unless the printer is set for marks on the front (media.bar_location set to front). Keep the 15 mm central strip free of any dark pre-printed graphics, and clean the sensor windows. |
| Zebra ZQ610 Plus | How do I calibrate a Zebra ZQ610 Plus? | The ZQ610 Plus is calibrated from the Tools menu, with the “Label Length Cal” function, which adjusts the label length. You can also set it to calibrate at start-up (Power Up Action) or when the printhead is closed (Head Close Action). |
| Zebra ZQ610 Plus | Why does my Zebra ZQ610 Plus fail to calibrate, as if the media were continuous? | The “Label Length Max” setting is probably shorter than the actual length of your labels: the printer then treats the media as continuous and calibration fails. Set it to at least 25.4 mm more than the label length plus the gap between labels, then recalibrate. |
| Zebra ZQ510 | How do I calibrate a Zebra ZQ510? | The ZQ510 is calibrated by commands sent from a computer, with Zebra Setup Utilities or the send file function of the ZDesigner driver. Specify the media type, send the calibration command, then switch the printer off and on again. |
| Zebra ZQ510 | Why does my Zebra ZQ510 skip labels or fail to detect black marks? | The sensor used does not match the media, or the marks and notches are not where the sensor expects them. By default, the ZQ510 uses the black mark sensor: with gap labels, set the detection mode then recalibrate. |
| Sato PW208NX | What does “Error 1028 (Gap Not Found)” or “Error 1035 (I-mark Not Found)” mean on my Sato PW208NX? | The printer cannot find the gap between labels (1028) or the black mark (1035). Reload the roll so that it feeds straight, clean the sensor, check the sensor type ([Gap] or [I-Mark]) and then run the calibration again. |
| Sato PW208NX | How do I calibrate the label sensor on my Sato PW208NX? | First choose the sensor type ([Gap] or [I-Mark]) in [Printing] > [Sensor Type], then run [Auto-calibration] in [Printing] > [Advanced] > [Calibrate], with only the liner (no label) placed over the sensor and the cover closed. On the PW208mNX, calibration is always done on the black mark. |
| Zebra ZD410 | How do I calibrate a Zebra ZD410 (SmartCal calibration)? | With the printer on and ready (STATUS light solid green), hold down PAUSE and CANCEL for two seconds, then release. The ZD410 feeds a few labels and adjusts its detection thresholds, then the STATUS light returns to solid green. |
| Zebra ZD410 | How do I run a manual media calibration on a Zebra ZD410 when SmartCal fails? | Enter advanced mode (hold PAUSE for two seconds), then start the manual calibration with PAUSE. The printer first measures the bare liner, then several labels; if it does not return to the ready state, start again, moving the movable sensor. |
| Zebra ZD411 | How do I calibrate a Zebra ZD411 (SmartCal calibration)? | With media loaded, the cover closed and the printer on, hold down PAUSE and CANCEL together for two seconds. The printer feeds and measures a few labels, then returns to the ready state. |
| Zebra ZD411 | My Zebra ZD411 will not calibrate with SmartCal: how do I run a manual media calibration? | Enter advanced mode by holding PAUSE for two seconds, then start the manual media calibration with PAUSE while the STATUS light is yellow. The printer first measures the bare liner, then the labels. |
| Zebra ZD420 | How do I calibrate a Zebra ZD420 with the PAUSE and CANCEL buttons? | The ZD420 calibrates without software: when STATUS is solid green, press PAUSE and CANCEL at the same time for 2 seconds, then release. The printer feeds and measures a few labels, then STATUS returns to solid green. |
| Zebra ZD420 | Zebra ZD420 manual calibration: what should I do when automatic calibration fails? | Enter advanced mode by holding PAUSE for 2 seconds: solid yellow STATUS corresponds to manual calibration. The printer then measures, in two stages, the liner on its own and then a label, as you press PAUSE. |
| Zebra ZD500R | How do I calibrate a Zebra ZD500R (labels and ribbon)? | Load the media (and the ribbon for thermal transfer), close the cover, then press and hold PAUSE, FEED and CANCEL for two seconds: the ZD500R starts calibrating the media and ribbon sensors. For RFID labels, follow up with an RFID calibration. |
| Zebra ZD500R | Why can't my Zebra ZD500R find the start of my labels (gap, notch or black mark)? | The media type set does not match the roll, or the movable sensor is in the wrong place. Set Media Type (CONTINUOUS, GAP/NOTCH or MARK) in the SETTINGS menu, leave the movable sensor in the centre for gap labels, then recalibrate. |
| Zebra ZD510-HC | Does a Zebra ZD510-HC need calibrating, and how do I check wristband detection? | The Zebra guide does not describe a manual calibration: on insertion, the cartridge chip automatically sets the length, print area, speed and darkness. If detection is a problem, print the media sensor profile (hold PAUSE/FEED until two orange flashes). |
| Zebra ZD611 | How do I run a SmartCal calibration on a Zebra ZD611? | With the printer ready (STATUS solid green), press PAUSE and CANCEL together for two seconds, then release. The ZD611 measures a few labels, sets its detection levels and returns to solid green. |
| Zebra ZD611 | How do I calibrate a Zebra ZD611 manually when SmartCal does not recognise the labels? | Enter advanced mode by holding PAUSE for two seconds with media loaded: all lights flash yellow, then STATUS stays solid yellow on the Manual Media Calibration mode. Press PAUSE to start it, then follow the steps to measure the liner and the labels. |
| Zebra ZD620 | How do I calibrate a Zebra ZD620 (SmartCal calibration)? | Run a SmartCal calibration: with the printer ready, hold PAUSE and CANCEL down for 2 seconds, then release. The ZD620 measures a few labels and sets its detection; the STATUS light returns to solid green at the end. |
| Zebra ZD620 | How do I perform a manual calibration on a Zebra ZD620 when SmartCal does not recognise the media? | Enter advanced mode (PAUSE held for 2 seconds), start manual calibration with PAUSE, then have the printer measure the liner alone, then a label. Zebra reserves this method for media that automatic calibration does not recognise correctly. |
| Zebra ZD621 | How do I calibrate a Zebra ZD621 with SmartCal? | On the ZD621, SmartCal calibration is started from the ready state by holding PAUSE and CANCEL down together for two seconds. The printer feeds and measures a few labels, sets its detection levels, then the STATUS light returns to solid green. |
| Zebra ZD621 | Why does my Zebra ZD621 skip labels or print out of position? | Zebra calls this a registration fault: media sensor badly positioned, sensors not calibrated for the media in use, platen roller slipping or a communication problem. Check the movable sensor, run a SmartCal calibration, then a manual calibration from the display if the skipping continues. |
| Zebra ZQ310 Plus | Why does my Zebra ZQ310 Plus not detect my labels or the black mark on my tickets? | Not all ZQ310 Plus printers can detect the gap between two labels: according to Zebra, only the Retail and Distribution versions (indoor use) have this sensor. The guide does not give a calibration using the buttons, but it does set rules for the black mark and for sensor maintenance. |
| Zebra ZQ320 Plus | My Zebra ZQ320 Plus does not detect the gap between labels or the black mark: what should I check? | First check that your version has the right sensor: only the “Retail and Distribution” ZQ320 Plus versions (indoor use) have a gap sensor and accept standard labels. The Zebra guide does not describe a calibration using the buttons; it does, however, give the rules for positioning black marks. |
| Zebra ZQ620 Plus | How do I calibrate a Zebra ZQ620 Plus? | The ZQ620 Plus is calibrated from the Tools menu, using the “Label Length Cal” function, which adjusts the label length. You can also have it calibrate automatically at start-up (Power Up Action) or when the printhead is closed (Head Close Action). |
| Zebra ZQ620 Plus | Why can my Zebra ZQ620 Plus not calibrate, as if the media were continuous? | If the maximum label length (Label Length Max) is shorter than the actual length, the printer treats the media as continuous and calibration fails. Set Label Length Max at least 25.4 mm (1 inch) above the length of the label plus the gap, then run the calibration again. |
| Zebra ZT231 | How do I run a manual sensor calibration on a Zebra ZT231? | On the touch display, open Print > Sensors > Manual Calibration, touch Start Calibration and follow the prompts, touching Next at each step. Shortcut: hold PAUSE + FEED + CANCEL for 2 seconds. At the end, press PAUSE to resume printing. |
| Zebra ZT231 | Why is my Zebra ZT231 printing out of position or skipping labels? | According to Zebra, the printer is not calibrated for the media, the media type is set incorrectly or the platen roller is dirty. Set Label Type, clean the platen roller, then calibrate. |
| Zebra ZT510 | How do I calibrate a Zebra ZT510 that is skipping labels? | Run the ribbon and media sensor calibration: with the printer ready, press and hold PAUSE and CANCEL for 2 seconds, or choose MEDIA/RIBBON CAL in the TOOLS menu. The media is first calibrated on the liner alone, without ribbon, then you reload the labels and ribbon. |
| Zebra ZT510 | Why does automatic calibration fail on my Zebra ZT510? | According to Zebra, the media or ribbon is incorrectly loaded, the sensors are dirty or incorrectly positioned, or the media type is set incorrectly. Check the loading, clean the sensors, correct MEDIA TYPE, then run a manual calibration. |
| Zebra ZT610 and ZT620 | How do I calibrate my Zebra ZT610 or ZT620? | Calibration sets the sensitivity of the media and ribbon sensors. On a ZT600 with the standard display, hold PAUSE and CANCEL for 2 seconds; on the colour touch display version, the Zebra guide offers automatic calibration and manual sensor calibration, and Zebra requires manual calibration for several RFID problems. |
| Zebra ZT610 and ZT620 | Why does my Zebra ZT610 or ZT620 skip labels or print out of position? | According to Zebra, the printer is not calibrated or the label format is incorrect. Calibrate the printer; if the misalignment persists, clean the platen roller and check the media type, the guides and the printhead pressure. |
| Honeywell MP Nova | How do I calibrate a Honeywell MP Nova4 or MP Nova6? | Hold down the control button for about 10 seconds and release it when the light flashes green: the printer starts quick media calibration. The same calibration can be started from the NETira CT utility (Sensor Calibration, Quick Media button). |
| Honeywell MP Nova | Why does my Honeywell MP Nova skip every other label? | Honeywell first mentions a layout too close to the top edge: leave a blank space of 8 dot rows, about 0.5 mm, at the top of the label. Then calibrate the media; if the fault persists, the sensor may be faulty. |
| Honeywell PC23d | How do I calibrate a Honeywell PC23d? | LCD version: open the main menu, then Wizards, Calibration and Media; the wizard calibrates the label stop sensor. Icon version: restart the printer and hold down the Print button as soon as only the Maintenance and Bluetooth icons remain lit; it feeds a few labels then prints two test labels. |
| Honeywell PC42 | How do I calibrate a Honeywell PC42t with the Print button? | With the printer ready, hold down the Print button for about two seconds then release: the PC42t prints several labels to calibrate its media sensor (testfeed). If you keep the button held down, it then prints a configuration label. |
| Honeywell PC42 | Why does my Honeywell PC42t keep feeding labels without stopping? | According to the Honeywell guide, a label stuck on the gap sensor prevents label detection. Remove it, clean the printhead, then run a calibration again with the Print button. |
| Honeywell PC43 | How do I calibrate a Honeywell PC43d or PC43t? | Icon version: turn the printer off and on again and hold down the Print button when only the Maintenance and Bluetooth icons remain lit; it feeds a few labels to set the media feed, then prints two test labels. LCD version: run the Wizards > Calibration > Media wizard, which calibrates the label stop sensor. |
| Honeywell PD43 | How do I calibrate my Honeywell PD43 when it skips labels or cannot find the start of the label? | On an icon model, turn the PD43 off and on again and hold down the Print button when only the Maintenance and Bluetooth icons remain lit: it feeds a few labels to set the feed, then prints two test labels. On a display model, run the Wizards > Calibration > Media wizard. |
| Honeywell PD43 | My Honeywell PD43 does not detect the black marks on my labels: how do I adjust the sensor? | According to Honeywell, the label stop sensor must be aligned with the black marks on the media to work best. Lift the print mechanism, slide the sensor opposite the marks, then recalibrate. |
| Honeywell PD45S | How do I calibrate a Honeywell PD45S (label sensors)? | With the Ready screen displayed, hold down the Print button: the PD45S calibrates its media sensors. You can also go through Main Menu > Wizards > Calibration > Media, which calibrates all the sensors and shows the print settings. |
| Honeywell PD45S | My Honeywell PD45S does not detect the gap between labels or the black mark: how do I adjust the sensor? | The gap sensor and the black mark sensor must be opposite the gap or the mark. Open the cover, move the sensor with its adjustment knob, using its blue light as a guide, clean the front sensor if needed, then recalibrate. |
| Honeywell PM23c | How do I calibrate my Honeywell PM23c when it skips labels or prints out of position? | First set the media type, then run the Wizards > Calibration > Media wizard on a touch model, or Services > Media Calibration on the web page, whatever the model. According to Honeywell, pressing Print during start-up, with the printhead lowered, also puts the PM23c into calibration mode. |
| Honeywell PM23c | How do I tell my Honeywell PM23c that I am using black mark labels or continuous paper? | The Honeywell manual asks you to set the media type after each loading: gaps, black mark, fixed-length continuous or variable-length continuous. On a touch model, this setting (Media Type) is among the print settings in the Settings menu; then recalibrate. |
| Honeywell PM45 and PM45c | How do I calibrate a Honeywell PM45 or PM45c? | With the printer ready, hold down the Print button: the PM45 starts a smart calibration. You can also press Print during start-up to enter calibration mode, provided the printhead is lowered. |
| Honeywell RP2 and RP4 | How do I calibrate a Honeywell RP2 or RP4 printer? | With the printer on and idle, hold down the Media button for about 2 seconds, then release it when calibration starts. You can also start calibration from the printer’s web page (Services > Media Calibration). |
| Honeywell RP2 and RP4 | Why does my Honeywell RP4 skip every other label? | The Honeywell guide first cites content placed too close to the top edge of the label: leave about 0.5 mm of white space at the top. Then calibrate the media; if the skipping continues, the media sensor may be faulty. |
| Toshiba B-EX6 | How do I calibrate the label sensor on my Toshiba B-EX6 (threshold setting)? | First place the sensor at the centre of the gap between labels, or of the black mark. If pre-printed labels are still not detected properly, use the threshold setting mode: PAUSE, press and hold PAUSE for 3 seconds, select the sensor, then feed at least 1.5 labels. |
| Sato CL4NX | How do I run an automatic sensor calibration on a Sato CL4NX or CL4NX Plus? | Run [Auto-calibration] in [Printing] > [Advanced] > [Calibrate]: the printer automatically sets the level of the gap sensor (Gap), the black mark sensor (I-Mark) or both. During the adjustment, the media must pass under the sensor guide and the head must be locked. |
| Sato CL4NX | Why do the labels on my Sato CL4NX not stop in the right place? | The Sato troubleshooting pages point to loading, the sensor type, a dirty sensor or platen roller, then the position settings. Reload the media, select the right sensor, clean, then correct the print or stop position. |
| Sato CL6NX Plus | How do I calibrate the label sensor on a Sato CL6NX Plus (auto-calibration)? | Sato calls this setting [Auto-calibration]: it automatically adjusts the level of the gap and black mark (I-Mark) sensors. It is started from the [Printing] > [Advanced] > [Calibrate] menu, with the head locked and the media fed under the sensor guide. |
| Sato CL6NX Plus | Why does my Sato CL6NX Plus not stop in the right place, or print offset on the label? | The Sato manual cites incorrectly loaded media, an unsuitable sensor type, a dirty sensor or platen roller, or a position that needs correcting. Reload the media, check [Sensor Type], clean, then adjust the print or stop position. |
| Sato CT4-LX | Why does my Sato CT4-LX show “1028 Gap Not Found” or “1035 I-mark Not Found”? | The printer cannot find the gap between the labels (1028) or the black mark (1035). Check that the media feeds straight, that the sensor type matches the media and that the sensor is clean, then run a calibration again. |
| Sato CT4-LX | How do I calibrate the label sensor on a Sato CT4-LX? | Auto-calibration is started from SETTINGS > Printing > Advanced > Calibrate > Auto-calibration. Load the media with one label peeled off, so that the sensor only sees the liner, then choose the sensor type to adjust. |
| Sato PW4NX | What does “Error 1028 (Gap Not Found)” or “Error 1035 (I-mark Not Found)” mean on my Sato PW4NX? | The printer cannot find the gap between labels (1028) or the black mark (1035). Reload the roll so that it feeds straight, clean the sensor, check the sensor type ([Gap] or [I-Mark]) and then run the calibration again. |
| Sato PW4NX | How do I calibrate the label sensor on my Sato PW4NX? | First choose the sensor type suited to the media ([Gap] or [I-Mark]), then run [Auto-calibration] in [Printing] > [Advanced] > [Calibrate], with only the liner (without a label) placed over the sensor. Then check the feed with FEED. |
| Sato WS2 | How do I calibrate the sensor on my Sato WS2 after changing the roll? | Quick method: with the media loaded and the cover closed, hold FEED for 3 seconds until LED 2 turns orange and LED 1 turns green, then release: calibration starts. System mode also lets you choose the transmissive or reflective sensor. |
| Sato WS2 | Why is the print incorrectly positioned on the wristbands or labels from my Sato WS2? | The WS2 manual cites unsuitable media, incorrect loading, a sensor that needs calibrating or a dirty sensor. Check the media, reload it, calibrate the sensor, then clean it if the offset persists. |
| Sato WS4 | How do I calibrate the label sensor on a Sato WS4? | Calibration is done without a computer, using system mode: with the printer off, hold FEED while switching it on and release when LED 1 is green and LED 2 is red (transmissive sensor) or LED 2 is orange (reflective sensor). Pressing FEED starts calibration. |
| Sato WS4 | Why is the print offset on the labels from my Sato WS4? | Sato cites unsuitable or incorrectly loaded media, the wrong sensor type, an uncalibrated or dirty sensor, and a drive roller that needs replacing. Reload the media, calibrate and then clean the sensor; if nothing changes, replace the rubber roller. |
| Godex DT200 | How do I calibrate a Godex DT200 and choose the right label sensor? | Send the ~S,SENSOR,0 command: according to GoDEX Europe, it starts the same auto-calibration as the calibration button. By default, the printer itself chooses between the reflective sensor and the transmissive sensor; for black mark labels, you can restrict it to the reflective sensor. |
| Godex DT200 | My Godex DT200 cannot find the gap between coloured or pre-printed labels: how do I adjust the sensor? | Lower the sensor detection threshold: GoDEX Europe sets it at 40 as standard and suggests 25 or 27 for coloured or pre-printed labels, with the ~S,SENSOR,X,Y,Z command. Do this after updating the firmware and running an auto-calibration in GoDoctor. |
| Godex EZ6250i and EZ6350i | How do I calibrate a Godex EZ6250i or EZ6350i (label auto-detection)? | Press the auto-calibration button for 2 seconds: the printer detects the labels and the ribbon. You can also switch the printer off and back on while holding FEED, or use the Analysis > Calibration menu. |
| Godex EZ6250i and EZ6350i | Why does my Godex EZ6250i skip labels? | The label height setting does not match the media, or dust is masking the sensor. Check the height setting, clean the sensor, then run the auto-detection again. |
| Godex G500 | How do I calibrate a Godex G500 (automatic label size detection)? | Switch the printer off, then switch it back on while holding the FEED button down. Release FEED when the READY light flashes red and STATUS lights up orange: the G500 measures the labels, saves their height, then prints a self-test page. |
| Godex G500 | Why does my Godex G500 skip labels or print out of position? | The calibration no longer matches the media or the sensor is masked. Run the label size calibration again, then check the label height setting, the cleanliness of the sensor and the paper guides. |
| Godex GE300 | How do I calibrate a Godex GE300 so that it detects labels automatically? | With the printer off, switch it back on while holding down the FEED button and release the button as soon as the light flashes red. The GE300 measures the media, stores the label height, then prints a self-test page. |
| Godex GE300 | Why does my Godex GE300 skip a label during printing? | The label height setting no longer matches the media, or dust is masking the sensor. Check these two points, then run automatic detection again so that the printer re-measures the labels. |
| Godex HD830i | How do I calibrate a Godex HD830i? | The calibration button is on the rear panel of the HD830i: one press starts automatic calibration. GoDEX Europe specifies that it is equivalent to the ~S,SENSOR,0 command, which can also be sent from GoDoctor. |
| Godex HD830i | My Godex HD830i cannot find the gap between labels longer than 250 mm: what should I do? | The HD830i prints labels up to 1,016 mm long, but a GoDEX printer only searches for the gap or mark over 250 mm by default. Extend this range with ~S,SENSOR (GoDEX example: ~S,SENSOR,400,3,30 for 400 mm), then run calibration again with the button. |
| Godex RT200 | How do I print the label sensor diagram on a Godex RT200 using the FEED button? | With media loaded and the printer switched on, open the printhead (one beep), press FEED six times (two beeps), close the printhead and run calibration: the printer prints the gap or mark sensor output diagram. GoDEX Europe recommends this for difficult media. |
| Godex ZX1000i | How do I calibrate a Godex ZX1200i (automatic label sensor calibration)? | Press the calibration button at the rear of the printer: the ZX1200i runs an automatic calibration on the loaded media. According to GoDEX Europe, this button has the same effect as the ~S,SENSOR,0 command, which you can also send from the GoDoctor utility. |
| Godex ZX1000i | Why does calibration fail on my Godex ZX1200i with very long labels? | By default, the printer only searches for the gap or mark over 250 mm. GoDEX Europe says to extend this distance with ~S,SENSOR (for example ~S,SENSOR,400,3,30 for 400 mm), then press the calibration button. |
| Godex ZX400 | How do I calibrate a Godex ZX420 or ZX420i (label auto-detection)? | Press the calibration button at the back of the printer for 1 to 2 seconds. Alternative method: switch it off, switch it back on while holding FEED and release the button when the READY light flashes red and the STATUS light turns orange. |
| Godex ZX400 | Why do the labels on my Godex ZX420 not stop in the right place when I press FEED? | The printer does not know, or no longer knows, the exact length of your labels. Check the sensor position, then run auto-detection again. |
| Brother TD-4 | How do I calibrate the label sensor (gap or black mark) on my Brother TD-4420TN? | With the printer off, hold down the Feed/Pause button, switch it on and release the button when the light has flashed red 5 times. You can also calibrate from the BPM tool: Printer Function, sensor type, then Calibrate. |
| Brother TD-4 | Why does my Brother TD-4 skip labels when printing? | Brother cites three causes: incorrectly set label size, unsuitable sensor sensitivity, dirty sensors. Check the size in BPM, change the detection threshold, then clean the gap and black mark sensors. |
| Brother TJ-4420TN | How do I calibrate the label sensor on a Brother TJ-4420TN? | On the display, open the menu, then Capteur (sensor) > Auto Calibration, and choose the type of consumable. Brother recommends calibrating on a new printer, each time you change media and after an initialisation. |
| Brother TJ-4420TN | Why does my Brother TJ-4420TN skip a label when printing? | According to Brother, the label size set is incorrect, the sensor sensitivity is incorrectly set, or the sensors are dusty. Check the width and height in BPM, clean the sensors, then calibrate again. |
Frequently asked questions
Do I need to recalibrate my label printer every time I change the roll?
Not for an identical roll: on the ZD410, ZD420 and ZD621, Zebra states that pressing FEED once or twice is enough with a roll of the same type, from the same supplier and the same batch. A calibration is needed when the media changes size, type, supplier or batch. Brother asks for the TJ-4420TN to be calibrated at every media change.
Why does my printer skip every other label?
On the Honeywell MP Nova and RP4, the guide first cites content placed too close to the top edge: leave about 0.5 mm of blank space at the top of the label. Then calibrate the media. If every other label is still skipped, Honeywell mentions a faulty media sensor and refers you to service.
Why doesn't my printer detect the gap between pre-printed labels?
Ink or dark pre-printed graphics can fool the sensor. Toshiba provides a manual adjustment of the detection threshold (B-852, B-EX4T1); Zebra recommends a manual calibration, with the sensor placed where it meets the least print (ZD410, ZD620). For coloured or pre-printed labels, GoDEX Europe suggests updating the firmware, calibrating, then lowering the sensor threshold from 40 to 25 or 27.
