Zebra ZD411 troubleshooting guide: errors, faults and fixes

Short answer: The cover is probably not fully latched. Close it by pressing both front corners of the cover until the latches click; if the alert persists with the cover properly closed, Zebra refers you to a technician for the head-open switch.

Likely cause

According to Zebra, the alert appears when a print command is sent or FEED is pressed while the printer detects that the cover (and therefore the head) is not closed. Two causes are cited: the cover not properly closed, or the head-open switch.

What to do

1. Close the printer cover.
2. Press both front corners on top of the cover until you hear the latches engage and lock.
3. Restart printing or press FEED: the alert should disappear.
4. If the alert returns even though the cover is properly latched, the head-open switch is at fault.

When to call a technician: if the alert persists with the cover latched, Zebra asks you to contact a service technician (head-open switch).

The Zebra guide groups this state under the label “Cover Open/Printhead (PH) Open” in the light table; the French guide calls it “Capot ouvert/tête d'impression ouverte”.

Short answer: The printer can no longer find any media in the paper path. If the roll is not empty, check the position of the movable sensor, the continuous / non-continuous setting and the cleanliness of the sensor, then run a SmartCal calibration.

Likely cause

Zebra lists seven causes: empty roll; a label missing in the middle of the roll (some suppliers remove one to signal the end); movable sensor badly positioned for the media type; printer set for gap or black mark labels while continuous media is loaded; dirty sensor (adhesive, dust); sensor that no longer works (corrupted data in memory); failed sensor.

Caution: Do not use the remaining labels on a roll with a missing label: Zebra states that they may leave behind the adhesive that holds them on the roll.

What to do

1. Empty roll: load a new roll.
2. Missing label: open the printer, pull the roll through to the next label at the front, close it, then press PAUSE. If the printer stays paused without feeding, press FEED once or twice.
3. Sensor badly positioned: adjust the movable sensor according to the media type (see the movable sensor entry).
4. Continuous media loaded while the printer expects labels: load the correct type of labels, or set the sensor for continuous media, finish loading and run a SmartCal calibration.
5. Dirty sensor: clean the movable sensor, then inspect and clean the roll compartment, the roll holders and the rest of the paper path.
6. Sensor no longer responding: Zebra recommends updating the firmware (see firmware update).

When to call a technician: if the media sensor has failed, Zebra asks you to call a service technician.

Short answer: The ZD411t detects the reflective strip that appears at the end of the ribbon roll. Open the printer without turning it off, remove the full take-up roll, load a new ribbon, close the printer and press FEED once to resume.

Likely cause

According to Zebra, ribbon out is detected by means of a reflective leader at the end of the roll, under the ribbon: when it appears, the printer signals ribbon out through its lights.

What to do

1. Open the printer without turning it off.
2. Check that the reflective leader is visible: the take-up roll should be full.
3. Remove the used take-up roll and dispose of it appropriately.
4. Load a new ribbon roll (see loading the ribbon).
5. Close the printer and press FEED once to resume printing.

Short answer: The printhead has overheated and the printer stops while it cools down. Printing resumes on its own; if the alert comes back often, move the printer away from heat or sunlight.

Likely cause

Zebra cites two causes: a large, very heavy print job (a lot of black on many labels), or an ambient temperature above the operating range, which direct exposure to sunlight can make worse inside the printer.

What to do

1. During a long, heavy job: do nothing. The printer pauses and resumes automatically when the head is cool enough.
2. If the room is too hot: install the printer in a cooler place, out of direct sunlight, or cool the area.
3. If the alert comes with STATUS and PAUSE flashing red, go to the PRINTHEAD SHUTDOWN entry.

The light table in the Zebra guide associates solid amber STATUS with head overheating (as well as with other states: head element fault, out of memory, USB host or serial power fault).

Short answer: The printhead is too cold to print correctly, usually because the room is below the minimum operating temperature. Warm the room or move the printer; if the alert persists in a room at a normal temperature, the head needs replacing.

Likely cause

According to Zebra, either the environment is colder than the intended operating range, or the printhead is faulty and stays below its operating temperature despite correct conditions.

Caution: Zebra warns that moisture can condense in and on the printer if the temperature changes too quickly: let it warm up slowly.

What to do

1. Raise the ambient temperature or install the printer in a warmer place.
2. After a severe cold spell or a power cut, turn the printer off and move it if necessary.
3. Let it warm up gradually, then reinstall it and turn it back on.
4. If the alert persists while the room is at the right temperature, have the printhead replaced.

Short answer: The head has been shut off for safety after critical overheating or a circuit fault. Turn the printer off by holding POWER for 5 seconds, let it cool down for a few minutes, then turn it back on; if the alert returns, the head needs replacing.

Likely cause

Zebra describes a protective shutdown of the printhead circuit, triggered by critical temperatures to protect the head.

What to do

1. Hold down the POWER button for 5 seconds to turn the printer off and wait until it has shut down completely.
2. Let it cool down for a few minutes.
3. Switch the printer back on.
4. If turning it off and letting it cool down is not enough, Zebra says to replace the printhead.

When to call a technician: if the printer does not clear this error, Zebra asks you to call a technician: it is not a task intended for the operator.

The Zebra light table associates STATUS flashing red and PAUSE flashing red with head overheating that requires cooling down and restarting.

Short answer: The printer no longer has enough memory to save a format, graphic, image or font. Delete unused items from memory or reduce the print area of the label.

Likely cause

Zebra states that the printer cannot save the data to the requested memory location. It handles four types of storage: graphic, format, bitmap image and font. The second line of the message specifies the type concerned.

What to do

1. Reduce the print area by adjusting the label format or the printer settings.
2. Delete graphics, fonts or formats that are no longer used.
3. Check that the data is not being sent to a storage device that is missing or unavailable.

Short answer: 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.

Likely cause

According to Zebra, SmartCal calibration quickly sets the printer for the loaded media: it automatically detects the type of registration (gap between labels, black line or notch) and measures the label length.

Official SmartCal calibration procedure

1. Check that the media is correctly loaded, that the cover is closed and that the printer is on.
2. Hold down the PAUSE and CANCEL buttons together for two seconds.
3. The printer feeds and measures several labels.
4. When it has finished, it returns to the ready state (READY).
5. If the printer does not recognise the media or does not calibrate correctly, move on to manual calibration.

Before calibrating, the movable sensor must be positioned according to the media type (see movable sensor).

Source: SmartCal Media Calibration (opens in a new window) – Zebra ZD411T user guide (official documentation).

Short answer: 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.

Likely cause

Zebra presents manual calibration as a set of sensor settings suited to media that is difficult to detect, to be used when SmartCal does not recognise the media.

Official manual calibration procedure

1. With media loaded and the printer on, hold PAUSE for two seconds: all the lights flash yellow, then STATUS turns solid yellow (first mode: manual media calibration). FEED cycles through the modes, CANCEL exits advanced mode.
2. Press PAUSE while STATUS is yellow: the SUPPLIES (media) light flashes yellow, then the PAUSE light flashes.
3. Open the printer and check that the sensor is centred for gap detection. For black mark or notched media, place it opposite the mark or notch; for pre-printed media, at the least printed spot.
4. Remove about 80 mm (3 inches) of labels from the liner.
5. Place the section of liner without labels over the platen roller, with the leading edge of the first label under the guides.
6. Close the printer and press PAUSE once: the SUPPLIES light flashes while the liner is measured, then the PAUSE light flashes.
7. Open the printer, place a label just above the movable sensor and close it again.
8. Press PAUSE once: the printer feeds and measures several labels. If it identifies the media type and its length, it returns to the ready state, STATUS solid green.
9. If it does not, move the sensor and repeat the calibration.

Sources: Manual Media Calibration Mode (opens in a new window) · Activating Advanced Mode (opens in a new window) – Zebra ZD411T user guide (official documentation).

Short answer: The media is incorrectly loaded, the movable sensor is badly positioned or the calibration is no longer correct. Reload the media, clean the paper path and the sensors, then run a SmartCal calibration; if the platen roller is worn, it must be replaced.

Likely cause

Zebra cites three causes: media needs reloading (incorrectly loaded, movable sensor badly adjusted or calibration needed); dirty printer interior; damaged or worn platen roller, which becomes smooth and grips the media less over time.

What to do

1. With the printer on, remove the media.
2. Inspect the paper path, the roll holders and the guides: look for paper dust and adhesive deposits. Also check that the platen roller is neither damaged nor dirty.
3. Check that the movable sensor is set and positioned for your type of media, and that its window is clean.
4. If necessary, clean in this order: the paper path, the sensors, the platen roller, and the printhead last.
5. Reload the media and run a SmartCal calibration.
6. If the platen roller is worn or damaged, replace it.

Short answer: The roll must turn freely, and the media must pass under both guides and extend past the front. Leave the movable sensor in the default position for gap labels; for a black mark or a notch, place its arrow in the middle of the mark.

Likely cause

According to Zebra, the movable sensor detects the media either by transmission (through the media, for the gaps between labels) or by reflection (black marks, notches), never both at the same time. Reflective detection does not work in the default position.

Caution: For dusting, Zebra prohibits the use of an air compressor: it introduces moisture, fine grit and lubricant that contaminate the printer. Use canned dry air.

Official loading procedure

1. Pull the release latches towards you to open the cover.
2. Pull the roll holders apart and place the roll: it must turn freely without resting on the bottom of the compartment.
3. Pull the end of the media past the front edge of the printer and slide it under both guides.
4. Adjust the movable sensor: default position for gap labels (web/gap); off-centre position for black marks or notches.
5. For a black mark or a notch: place the alignment arrow in the middle of the mark, with the sensor as far as possible from the edge of the media and the mark covering the whole sensor window.
6. Close the cover and run a SmartCal calibration.
7. Dirty sensor: dust the movable sensor window with a brush or canned dry air, then with a dry swab; if adhesive remains, use a swab moistened with alcohol and finish with a dry swab, until there are no deposits or marks left. The gap sensor under the head is cleaned the same way, starting with canned dry air.

Zebra points out that the media can shift by about ±1 mm during printing and that notches can be damaged by handling: hence the importance of centring the sensor properly.

Short answer: Place an empty core on the take-up spindle and the new ribbon on the lower spindle, notches on the left, attach the leader to the core and then tension the ribbon. After closing, feed at least 20 cm of media with FEED to remove the wrinkles, then set the print mode to thermal transfer.

Likely cause

The Zebra guide specifies that feeding at least 20 cm after loading removes slack and wrinkles from the ribbon and aligns it on the spindles, and that the print mode must be changed from direct thermal to thermal transfer.

Official ribbon loading procedure

1. Remove the ribbon packaging and peel off its adhesive strip. Check that the ribbon and the empty cores have their notches on the left.
2. Open the printer. Fit an empty core onto the take-up spindle: right side onto the spring-loaded spindle, left side centred on the hub, then turn it until the notches line up and lock. The first take-up core is supplied in the box.
3. Place the new ribbon roll on the lower supply spindle and lock it in the same way.
4. Attach the ribbon to the take-up core with the adhesive strip (or a thin piece of adhesive tape), lining it up so that it winds on straight.
5. Turn the take-up hub, top towards the back, to remove the slack: the leader must be completely covered by ribbon.
6. Check that the media is loaded, then close the cover.
7. With the printer on, press FEED to feed at least 20 cm of media.
8. Switch the print mode to thermal transfer via the driver, ZebraDesigner or the ZPL command ^MT.
9. Check with a configuration report: the PRINT METHOD field should show THERMAL-TRANS.

The ZD411d and the ZD411-HC print in direct thermal mode, without a ribbon.

Short answer: Deposits on the platen roller make the media slip or stick and can damage the head. Remove the roller and clean it with isopropyl alcohol from the centre outwards; if the media still sticks or jams after cleaning, Zebra asks you to replace it.

Likely cause

According to Zebra, contaminants on the platen roller can damage the printhead or make the media slip or stick. Over time, the roller wears, becomes smoother and grips less.

Official roller cleaning procedure

1. Prepare a fibre-free swab (or a clean, lint-free cloth) and pure isopropyl alcohol of at least 99.7%.
2. Open the cover (and the dispenser door if it is installed) and remove the media from the roller area.
3. Pull the left and right latch tabs towards you, then rotate them upwards.
4. Lift the roller by its bearing arms and take it out of the chassis; remove the gear and the two bearings from the shaft.
5. Clean the roller with a swab lightly moistened with alcohol, from the centre outwards, until the whole surface is clean. Throw away the used swabs.
6. Reassembly: put the bearings and gear back on the shaft, align the gear on the left, lower the roller into the chassis and lock the tabs towards the back.
7. Let it dry for one minute before closing or loading labels.

If the media continues to stick or jam after cleaning, the platen roller must be replaced.

Short answer: A dirty head distorts the image or leaves voids. Open the printer, remove the ribbon if there is one, run a new cleaning pen over the dark strip of the head from the centre outwards, then wait one minute before closing.

Likely cause

Zebra states that a dirty head distorts the image or creates voids in the print, and recommends cleaning the head every five rolls printed, or each time the media or ribbon is changed.

Caution: Zebra warns that the printhead becomes hot during printing: avoid touching it, so as not to damage it or injure yourself. Electrostatic discharge can damage or destroy the head and the electronic components: follow anti-static precautions under the cover. Use only the cleaning pen to maintain the head.

Official printhead cleaning procedure

1. Open the printer.
2. If a transfer ribbon is installed (ZD411t), remove it.
3. With a new cleaning pen, rub the dark strip of the printhead working from the centre outwards: this pushes the adhesive that has built up on the edges of the media out of the paper path.
4. Do not use the pen on the platen roller.
5. Wait one minute before closing the printer.
6. If the print is still faded, check the darkness and the speed using the print quality entry.

According to the Zebra maintenance schedule: head every 5 rolls, platen roller and paper path as needed (isopropyl alcohol of at least 99.7%, let it evaporate completely).

Sources: Cleaning the ZD411T Printhead (opens in a new window) · Recommended Cleaning Schedule (opens in a new window) · Issue: General Print Quality Issues (opens in a new window) – Zebra ZD411T user guide (official documentation).

Short answer: Zebra first cites a darkness or speed setting unsuited to the media: print the print quality report (FEED self-test) to find the right combination. Then check that the head and platen roller are clean and, in thermal transfer, that the ribbon and labels are matched.

Likely cause

The Zebra guide lists six causes: darkness and/or speed set incorrectly for the media; dirty printhead; dirty or damaged platen roller; worn head; in thermal transfer, ribbon (wax, wax-resin or resin) unsuited to the media (paper, coated, synthetic); power supply with insufficient voltage or power.

Caution: Zebra asks you never to set the print speed above the maximum speed specified by the media and ribbon manufacturer.

What to do

1. Print the print quality report (FEED self-test) to determine the ideal darkness and speed, then adjust these settings.
2. Clean the printhead (see printhead cleaning).
3. Clean or replace the platen roller: it wears and can be damaged.
4. ZD411t in thermal transfer: check that the ribbon type suits the media and set a speed no higher than the maximum speed recommended for the ribbon.
5. If the head is worn, replace it.
6. Check that you are using the power supply intended for the printer: printing requires a lot of power.

Source: Issue: General Print Quality Issues (opens in a new window) – Zebra ZD411T user guide (official documentation).

Short answer: Print the print quality report (FEED self-test): turn the printer off, then hold FEED while turning it back on until only STATUS stays on. Choose the clearest label and apply its darkness and speed.

Likely cause

Zebra explains that a label that is too dark widens the bars and fills in small characters, and that a label that is too light gives incomplete bars. The right setting depends on the combination of media, ribbon and speed.

Official procedure (FEED self-test)

1. Load full-width media.
2. Print a configuration report (FEED + CANCEL held for two seconds) to note the current darkness.
3. Turn the printer off, then hold down FEED while turning it back on; release when only the STATUS light stays on.
4. The printer prints a series of labels at two speeds (51 mm/s, then 152 mm/s at 203 dpi or 102 mm/s at 300 dpi), seven per speed, from -3 to +3 darkness steps around the current setting.
5. Choose the best label, using a barcode verifier if possible, otherwise by eye or with your scanner.
6. Add its relative darkness to, or subtract it from, the value in the configuration report, then apply the new darkness and the speed if they differ from the current settings.

Zebra points out that only a verifier can guarantee that a barcode complies, and that the test must be repeated each time the media, ribbon or speed changes.

Short answer: The printer cannot read the head resolution or does not recognise it as a genuine Zebra head. Check how the head is fitted and install a genuine Zebra head to resume printing.

Likely cause

According to the Zebra light table, the resolution error appears when the printer cannot read the resolution (dpi) of the head, because it was replaced incorrectly or is not a Zebra head; the unauthorised head error indicates a head that is not genuine Zebra.

Caution: Zebra asks you to read the whole replacement procedure before starting. The head becomes hot during printing: avoid touching it. Follow anti-static precautions, as electrostatic discharge can destroy the head and the components under the cover.

What to do

1. Turn the printer off and check how the head is fitted: both harness connectors plugged in, the head locked in place and moving freely up and down.
2. If the head is not a genuine Zebra head, install a genuine Zebra head.
3. Clean the new head with a new cleaning pen, from the centre outwards, reconnect the power, load full-width media and print a configuration report to test it.

Short answer: The USB cable was connected before the Zebra driver was installed: Windows installed a generic driver. Disconnect the cable, remove the “Unspecified” entry, install the Zebra driver, then reconnect the printer.

Likely cause

According to Zebra, if the printer is connected by USB before the drivers are pre-installed, Windows assigns it its generic driver and places it among the “Unspecified” devices: the Zebra printer is not recognised correctly.

What to do

1. Disconnect the printer's USB cable at the computer end.
2. Open Control Panel (search in the taskbar), then Devices and Printers: the Zebra printer is listed under “Unspecified” and not in the Printers section.
3. Select this misclassified Zebra entry and remove it. Zebra specifies that the names of its printers start with the prefix “ZTC”, which helps you find it.
4. Install the Zebra Windows printer driver (the guide cites version v8) if you have not already done so.
5. Reconnect the USB cable: the printer should now appear in the Printers section.

Source: Issue: USB Printer Fails to Install after Connecting Printer (Before Installing the Printer Driver) (opens in a new window) – Zebra ZD411T user guide (official documentation).

Short answer: The communication settings are probably incorrect, especially on a serial link. Check the driver or software settings, then, on serial, the handshake protocol and the type and length of the cable.

Likely cause

Zebra attributes this case to incorrect communication settings, a typical situation with serial interface connections.

What to do

1. Check the communication settings in the printer driver or the labelling software.
2. On a serial link: check that the handshake protocol and the printer's serial port settings match those of the computer.
3. Check the serial cable: wrong type (DTE or DCE), damaged cable or cable longer than the RS-232 standard allows.
4. Check that the interface cable is not too long, that it meets the specifications and that it is shielded; keep it away from sources of interference (fluorescent lighting, transformers, motors).

The DATA light flashes green during a data transfer; it stays off if there is no transfer.

Short answer: First check both ends of the network cable and the wired IP protocol setting (often DHCP). If the address changes at each restart, assign a fixed IP address and reset the network.

Likely cause

Zebra cites three causes: cable not plugged in properly; printer incorrectly configured for the network, most often for DHCP; network settings that let the network reassign an address at each power-up.

What to do

1. Check that the Ethernet cable is properly connected at both ends. With the Ethernet card, the NETWORK light off indicates no link; green, a 10/100 link; amber, a 10 Base link; red, a fault.
2. Check that the wired IP protocol parameter (Wired IP Protocol) matches your network (DHCP or fixed address).
3. If the address changes after turning off: note the IP address, subnet mask and gateway to keep, set the IP protocol to PERMANENT, enter these values, then reset the network to apply the changes.

On the ZD411, the Ethernet connection goes through an optional connectivity module.

Sources: Printer Connectivity Issues (opens in a new window) · ZD411T Standard Interface Controls (opens in a new window) – Zebra ZD411T user guide (official documentation).

Short answer: Most often, the network name (ESSID) has not been entered or a network value is wrong. Print the network configuration report, correct the ESSID and the other values, then reset the network so that they are applied.

Likely cause

Zebra lists three cases: no ESSID defined; incorrect ESSID or other network value; IP address, mask and gateway entered manually without resetting the network, although a reset is required after any change.

What to do

1. Read the NETWORK light: flashing red during association with the network, flashing amber during authentication, solid green when connected with a good signal, flashing green when connected with a weak signal, solid red if there is a fault.
2. Print a network configuration report and check the ESSID and the other settings.
3. If the ESSID is empty or wrong, set it to match your router. Zebra gives the command ! U1 setvar "wlan.essid" "valeur"; the ESSID is often on a label on the router, otherwise ask your network administrator for it.
4. After any change (ESSID, IP address, mask, gateway), reset the network to apply the values.

Wi-Fi (with Bluetooth) goes through an optional wireless module. Network IDs and passwords are not included in this guide: refer to the Zebra guide and your network administrator.

Short answer: The printer is probably in protected mode, which locks these settings without a password. Zebra refers you to the Link-OS PrintSecure administration guide to change them with the JSON commands provided.

Likely cause

According to Zebra, protected mode prevents the wired, wireless and Bluetooth settings from being changed without the password for this mode.

What to do

1. Check with your IT department whether protected mode is enabled on the printer.
2. Use the protected mode password with the JSON commands described in the Zebra Link-OS PrintSecure Printer Administration Guide.
3. For a printer purchased in the EMEA region after 1 August 2025, note that many connectivity options are disabled by default: Zebra refers you to zebra.com/asr for details and a setup wizard.

No default password is given here: it is covered by the Zebra documentation and your administrator.

Short answer: The cutter blade is stuck and no longer moves correctly. The cutter is not user-serviceable: clean only its outer cover and call in a technician for everything else.

Likely cause

In the light table, Zebra describes the cutting error (Cut Error, binding) as a stuck cutter blade that no longer moves correctly. The maintenance schedule specifies that unapproved tools, swabs or solvents (including alcohol) can damage the cutter or cause it to jam.

Caution: Zebra asks you never to remove the cutter cover (bezel) and never to insert any object or finger into the cutting mechanism. Do not clean the opening or the blade.

What to do

1. Do not try to free the blade yourself: Zebra classifies the cutter as not operator-serviceable.
2. You may only clean the outside of the cutter cover (bezel).
3. Do not use any swab, solvent or alcohol inside: the special coating of the blade could be damaged and the mechanism could jam.
4. For any internal cleaning or unjamming, call in a service technician.

When to call a technician: for any cleaning or unjamming inside the cutter, Zebra refers you to a service technician.

The dedicated alert page (“Alert: Cut Error”) could not be opened; this entry is based on the light table and the maintenance schedule in the same guide. The cutter is an option that can be installed on site.

Short answer: If STATUS is slowly pulsing green, the printer is simply in sleep mode: a brief press on POWER wakes it up. Otherwise, check the connection of the supplied power supply: its light should turn green when the socket is live.

Likely cause

According to Zebra, a brief press on POWER puts the printer into low-power mode (Energy Star): all the lights go off except STATUS, which pulses slowly. The guide also points out that the printer must be powered by the power supply intended for it.

Caution: Zebra asks you never to operate the printer or its power supply in a damp place, and not to place anything under or around the base of the printer, to avoid overheating.

What to do

1. STATUS slowly pulsing green: the printer is in sleep mode, press POWER briefly.
2. No light: connect the power supply to the printer's power socket, the mains cord to the power supply, then the cord to a suitable mains socket.
3. Check that the light on the power supply turns green.
4. Press POWER until the lights come on: they flash during the self-tests, then STATUS turns solid green when the printer is ready.
5. Use only the power supply designed for the printer: a power supply with a lower voltage or power rating is not suitable.
6. To turn it off, hold POWER for 4 to 9 seconds.

With the optional battery base, see also the battery lights entry.

Short answer: A solid red battery status light indicates an internal error: remove the battery. Flashing red, it indicates a charging error or a temperature out of range; with no charge bar lit, the battery must be recharged before the printer can be turned on.

Likely cause

The ZD411 accepts an optional battery base, which acts as an uninterruptible power supply. The Zebra guide describes two lights: the battery's state of health and its charge level.

Caution: Zebra specifies that the battery can be recharged without the printer, but only with a power source approved by Zebra.

Reading the battery lights

1. Battery Health green: battery in good condition, charging complete, ready to use.
2. Battery Health orange: charging (printer off).
3. Battery Health red: internal error. Remove the battery and refer to the troubleshooting section of the guide.
4. Battery Health flashing red: charging error, temperature out of range or internal monitoring error.
5. Charge Level: three solid green bars, fully charged; two bars with the top one flashing, incomplete charge; one flashing green bar or no bar, battery needs recharging (with no bar, the printer cannot turn on).
6. Battery button: a brief press wakes it from sleep or shutdown (the three lights flash and you have one minute to turn on the printer); a press of 10 to 11 seconds turns it off, confirmed by three flashes.

Short answer: The battery has detected a fault: end of life, component failure, or battery too hot or too cold. Remove it, let it return to room temperature, recharge it and check its charge; if that does not work, replace it.

Likely cause

Zebra cites two causes: battery at the end of its useful life or with a component failure; battery too hot or too cold.

Caution: Dispose of the old battery in accordance with local regulations.

What to do

1. Remove the battery from the printer and recharge it to check its state of charge.
2. Let it return to room temperature (cool down or warm up), then check its charge again.
3. If the fault persists, install a new, fully charged battery.

Short answer: Turn the printer off, hold PAUSE and FEED while turning it back on until only the STATUS light stays on, then release and recalibrate. For the network settings only, the combination is PAUSE and CANCEL.

Likely cause

Zebra provides two separate self-tests: PAUSE + FEED restores the printer's non-network factory settings; PAUSE + CANCEL restores the factory network settings.

Official procedure

1. Printer settings: turn it off, hold PAUSE and FEED, then turn it back on without releasing them.
2. Keep the buttons held down until only the STATUS light is on, then release.
3. Recalibrate the printer for the media in use with a SmartCal calibration.
4. Network settings: turn the printer off, hold PAUSE and CANCEL while turning it back on, until only STATUS stays on.

The PAUSE + FEED reset does not affect the network settings. Zebra also mentions a reset button located underneath the printer.

Short answer: The Zebra guide describes the update with Zebra Setup Utilities: open the printer tools, Action tab, and send the firmware. The DATA light flashes green during the download, the printer restarts, then STATUS stays solid green and a configuration report prints.

Likely cause

According to Zebra, firmware updates bring new features and improvements to media handling and communications. The guide also advises reloading the firmware when the media sensor no longer responds or when the printer locks up.

Official procedure (Zebra Setup Utilities)

1. Load media into the printer: a configuration report will print at the end.
2. Open Zebra Setup Utilities and select the installed printer.
3. Click “Open Printer Tools” to open the tools window, then open the Action tab to send the firmware file.
4. The firmware is downloaded only if its version differs from the one installed. During the download, the DATA light flashes green.
5. The printer restarts and all its lights flash.
6. The update is complete when the STATUS light stays solid green and a configuration report prints automatically.

Short answer: Zebra suggests corrupted memory. Restore the factory settings, then reload the firmware; if the printer does not start working again, call in a technician.

Likely cause

According to Zebra, the printer memory has been corrupted by an unknown event.

What to do

1. Restore the factory settings, using the PAUSE + FEED self-test (see reset) or from Zebra Setup Utilities (printer tools, load default settings).
2. Reload the printer firmware (see firmware update).
3. If the printer does not recover, stop there: this is not a task intended for the user.

When to call a technician: if the printer is still stuck after the reset and reloading the firmware, Zebra asks you to call a service technician.
