Honeywell RP2 and RP4 troubleshooting guide: errors, faults and fixes

Short answer: According to Honeywell, the Media button flashes red when there is no media in the printer. Reload the roll, close the cover until it latches, then press the Media button to clear the alert.

Likely cause

The RP2f/RP4f quick start guide states that the button flashes red when there is no paper in the printer. If a roll is loaded nonetheless, see the out of media although the roll is loaded entry.

What to do

1. Press the latch and lift the cover.
2. Spread the hubs apart, insert a roll in the direction shown in the guide, then let the hubs close on the roll.
3. Close the cover, pressing down until it latches.
4. Press the Media button 2 or 3 times: each press feeds the paper to the start of the next label.
5. The Troubleshooting chapter of the user guide specifies that once the problem has been corrected, you must press the Media button to clear the alert.

The guide also states that, with media present, pressing and holding the button performs a test feed.

Short answer: Honeywell cites paper dust on the media sensor. Clean the sensor with compressed air, then recalibrate by holding the Media button for about 2 seconds while the printer is idle.

Likely cause

According to the troubleshooting table in the RP2f/RP4f user guide, paper dust covering the sensor prevents it from seeing the media. The maintenance schedule in the same guide calls for monthly cleaning of the media sensor with compressed air.

What to do

1. Open the cover and remove the roll.
2. Blow compressed air onto the media sensor.
3. Reload the roll and close the cover until it latches.
4. Calibrate the media (see the calibration entry).

Source: RP2f/RP4f User Guide – Mobile Printers – Honeywell RP2f/RP4f user guide (RP2f4f-EN-UG-01) (official documentation).

Short answer: Honeywell’s online help for the RP4F states that if the wrong media type is selected, the printer shows a media error after a single print. Correct the media type in the configuration, then recalibrate.

Likely cause

The media type set in the printer does not match the media loaded. According to the user guide, the default setting is “Media With Gaps” (labels separated by a gap).

What to do

1. On a PC connected to the same network, open a browser and enter https:// followed by the printer’s IP address.
2. Click Login and sign in with an administrator account (credentials: see the Honeywell user guide).
3. Open Configure > Printing > Media.
4. Set Media Type to match the media actually loaded, then click Save.
5. Run a calibration (see the calibration entry).

According to the user guide, “Smart Calibration” detects by itself whether the media has gaps, black marks or is continuous, and calibrates its length.

Short answer: According to the Honeywell guide, all lights flashing red indicate a temperature error: the printer is too hot or too cold to print. Move it back to a temperate environment before printing again.

Likely cause

Printer temperature outside its operating range. The user guide gives a maximum operating temperature of 55 °C and a maximum charging temperature of 40 °C with the Honeywell power supply; the note on the power supply mentions a range of 0 to 40 °C.

Caution: Honeywell asks you not to place the printer near a heat source, and to keep the battery away from fire and heat.

What to do

1. Stop using the printer and move it away from any heat source (or from the cold).
2. Let it return to a temperature suitable for printing.
3. Do not charge it above 40 °C.

Short answer: These are system alerts listed in the default settings of the Honeywell guide. Only “Out of Media” and “Printhead Lifted” are enabled by default; the other alerts remain disabled until you enable them.

Likely cause

The guide classifies the alerts into three levels. Errors: Next Label Not Found, Out of Media, Printer in Pause Mode, Application Break, Printhead Lifted, Printhead Not Detected, Printhead Too Hot, Motor Too Hot, Power Supply Too Hot, Memory Full, Flash Memory Full. Warnings: Upgrading Firmware, counters (Odometer) that have reached their threshold, Replace Printhead, Clean Printhead, Faulty Dot, Memory Low, Flash Memory Low. Information: end of job, start-up, restart.

What to do

1. Error-Out of media: reload the media (see the no media entry).
2. Error-Printhead lifted: check that the cover is closed until it latches, as the loading procedure requires.
3. Error-Next label not found: recalibrate the media (see the calibration entry).
4. Warning-Clean printhead: clean the printhead (see the faded print entry).
5. The printer and printhead counters (Printer Odometer) can be viewed on the printer’s web page, System Information tab.

When to call a technician: if the printhead is faulty, the Honeywell guide asks you to contact service.

The guide lists these alerts in its default settings appendix, without detailing how they are delivered. The RP2 and RP4 have no display to show them.

Short answer: 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).

Likely cause

Honeywell recommends calibrating after loading media if necessary, when the printer does not print or feeds several labels at once, when it skips labels, and after a firmware update.

Official calibration procedure

1. Load the media and close the cover until it latches.
2. Check that the printer is idle (no print job in progress).
3. Press and hold the Media (Feed) button for about 2 seconds, then release it as soon as calibration begins.
4. Alternative method: on the printer’s web page, open Services > Media Calibration, click the blue Media Calibration button and wait for the message saying calibration is complete.
5. After loading, press the Media button 2 or 3 times to even out the feed: each press brings the paper to the start of the next label.

By default, pressing and holding the Media button runs a “Smart Calibration”, which recognises the media type and calibrates its length. The default calibration mode is “Slow”; Honeywell recommends this mode if the printer has trouble finding the gaps or marks.

Short answer: 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.

Likely cause

Honeywell gives three causes: a layout too close to the top edge of the label, uncalibrated media, or a faulty media sensor (or sensor circuit).

What to do

1. In your label template, leave about 0.5 mm (0.02 inch) of white space above the content.
2. Calibrate the media (see the calibration entry).
3. If the skipping persists, have the media sensor checked.

When to call a technician: if labels are still skipped after correcting the layout and calibrating, Honeywell suggests a faulty media sensor and refers you to service.

Source: RP2f/RP4f User Guide – Mobile Printers – Honeywell RP2f/RP4f user guide (RP2f4f-EN-UG-01) (official documentation).

Short answer: Honeywell cites incorrectly loaded labels or uncalibrated media. Reload the roll, then calibrate; if nothing changes, the media sensor circuit may be at fault.

Likely cause

According to the Honeywell troubleshooting table: incorrectly loaded labels, uncalibrated media, or a faulty media sensor circuit.

What to do

1. Reload the roll following the label loading entry.
2. Calibrate the media (see the calibration entry).
3. If the printer does nothing at all any more, also check the battery charge (see the pending print jobs entry).

When to call a technician: if the fault persists after reloading and calibrating, the guide suggests a faulty sensor circuit and refers you to service.

Short answer: Honeywell links this symptom to incorrectly loaded media. Check that the hubs are touching the roll and that the gaps or marks pass in front of the sensor; otherwise, the sensor circuit may be faulty.

Likely cause

According to the Honeywell troubleshooting table: incorrectly loaded media, or a faulty media sensor circuit.

What to do

1. Open the cover and check that the hubs are in proper contact with the roll.
2. Check that the gaps or black marks on the media are aligned with the sensor.
3. Close the cover and calibrate (see the calibration entry).

When to call a technician: if the fault recurs with correctly loaded media, the guide suggests a faulty sensor circuit and refers you to service.

Source: RP2f/RP4f User Guide – Mobile Printers – Honeywell RP2f/RP4f user guide (RP2f4f-EN-UG-01) (official documentation).

Short answer: According to Honeywell, the media is incorrectly loaded. Reload it, checking the position of the hubs and the alignment of the gaps or marks with the sensor, then press the Media button 2 or 3 times.

Likely cause

Incorrectly loaded media: hubs not positioned correctly against the roll, or gaps and marks misaligned with the sensor.

What to do

Short answer: On linerless models, Honeywell provides cleaning pens to remove the adhesive deposited on the printhead and rollers, every 3 to 5 rolls. If the media slips, increase the Feed Strength setting, which is set to Low by default.

Likely cause

Linerless labels leave adhesive on the parts they touch. The guide also states that the feed force (Feed Strength) must be increased if the media slips, for example with linerless media.

What to do

1. Rub the cleaning pen along the sticky part to loosen the adhesive deposits.
2. Rub again to remove the deposits.
3. If there is heavy build-up, use the plastic scraper on the pen cap.
4. If the media slips, increase Feed Strength in the Media settings on the printer’s web page (Configure > Printing > Media).

Honeywell also recommends the cleaning pens for any model that shows adhesive deposits.

Source: RP2f/RP4f User Guide – Mobile Printers – Honeywell RP2f/RP4f user guide (RP2f4f-EN-UG-01) (official documentation).

Short answer: Honeywell first cites a dirty printhead: clean it with a cleaning card or a cotton swab moistened with isopropyl alcohol. Then check that the darkness setting (heat, speed) suits the media.

Likely cause

According to the guide, non-compliant barcodes, print voids and streaks are generally caused by debris on the printhead. Build-up that is not removed can shorten the life of the printhead or put it out of service. Other causes cited: a darkness setting unsuited to the media, a faulty printhead.

Caution: Remove all the media before cleaning. Honeywell asks you never to spill liquid into the printer.

Official printhead cleaning procedure

1. Open the printer and remove all the media.
2. Open the fan-fold paper door, underneath the printer.
3. Insert the cleaning card through this door, then close the cover.
4. Press the Media button several times to feed the card through; repeat if necessary.
5. Reload the media, close the printer and press the Media button to feed the media.
6. If the print is still faded, adjust the heat or speed with PrintSet 5, the printer’s web page or commands.

When to call a technician: if the printhead is faulty, Honeywell asks you to contact service.

The guide describes the cleaning card for standard RP4f models. Its maintenance schedule specifies, for the printhead, a cleaning card or a cotton swab moistened with isopropyl alcohol, every 3 to 5 rolls of media (cleaning pens on linerless models).

Short answer: The Honeywell guide cites a cover that is not properly latched: close it until it latches. If the print is still light on the right, the printhead may be misaligned and Honeywell refers you to service.

Likely cause

Two causes according to Honeywell: cover not latched, or printhead misaligned.

What to do

1. Open and then close the cover, pressing down until it latches.
2. Print a test label to check the result.
3. If the fault persists, have the printhead alignment checked.

Short answer: Honeywell specifies cleaning the printhead, the platen roller, the peel roller and the cover roller every 3 to 5 rolls of media. The media sensor is cleaned with compressed air every month, and the interior as needed.

Likely cause

Debris built up on the printhead causes streaks, voids and non-compliant barcodes, and can shorten the life of the printhead.

Caution: Remove the media before cleaning, and never spill liquid into the printer.

Maintenance schedule from the Honeywell guide

1. Printhead: cleaning card or cotton swab moistened with isopropyl alcohol (cleaning pens on linerless models), every 3 to 5 rolls.
2. Platen roller and cover roller: cotton swab moistened with isopropyl alcohol (pens on linerless models), every 3 to 5 rolls.
3. Peel roller: cleaning pens, every 3 to 5 rolls.
4. Media sensor: compressed air, once a month.
5. Inside the printer: compressed air, as needed.

Short answer: Pair the printer using your device’s usual Bluetooth procedure: it appears as an available printer. With an Android phone, place the phone on the printer, then press the Media button once within 30 seconds to confirm pairing.

Likely cause

According to Honeywell, a Bluetooth light that is off means that the radio is switched off or disabled, that the printer is not paired with any device or that it is switched off.

Tap-to-pair (Android)

1. Place the Android phone on the printer: it recognises the printer and offers to pair.
2. The printer beeps and its Bluetooth icon flashes for up to 30 seconds.
3. Press the Media button once to complete pairing: the icon stops flashing.
4. If the button is not pressed within 30 seconds, pairing is cancelled; pressing the Power button cancels it immediately.
5. Check the pairing in the phone’s Bluetooth settings.

Bluetooth settings can be changed with PrintSet 5 or on the web page (Configure > Communication > Bluetooth). If the Reserve setting is enabled (disabled by default), the first device to connect blocks the others; the Discover setting (enabled by default) makes the printer visible. To print from Android, Honeywell suggests the Print Service by Honeywell app.

Short answer: A Wi-Fi light that is off means that the radio is switched off or disabled, or that the printer is not associated with any network. Configure Wi-Fi with PrintSet 5 over USB, or from the printer’s web page (Configure > Communication > Wireless 802.11).

Likely cause

Wi-Fi radio disabled, printer not associated with the network, or unsuitable network settings. The default network setting is DHCP.

What to do

1. Connect the printer via USB and configure Wi-Fi with PrintSet 5, or use the web page if the printer is already on the network.
2. On the web page: sign in with an administrator account, click Configure, then Communication > Wireless 802.11; change the settings and click Save.
3. On a network without DHCP, configure Wi-Fi with programming commands sent from a terminal.
4. To find the IP address, wait for the Wi-Fi light to come on, then send the command SETUP WRITE "Communications","stdout" from a terminal program.
5. For enhanced security, install authentication certificates after setting the printer’s date and time.

The Default Settings button on the Wireless 802.11 page restores all the Wi-Fi settings to their defaults. The configuration label also prints the wireless and security settings (see the configuration label entry).

Short answer: The default USB class is Composite (CDC/Printer Class). On some mobile computers with limited support, Honeywell asks you to choose CDC or Printer Class instead.

Likely cause

USB class not supported by the host, or driver not installed.

What to do

1. Switch off the printer before connecting a power or interface cable.
2. Connect the printer to the host with a Mini B to USB A cable, then switch it on.
3. On a mobile computer, change the USB class to CDC or Printer Class if the connection fails.
4. On a Windows PC, if the installation does not start, open Devices and Printers, then Add a printer.
5. Without a driver: the virtual COM port is active by default; in PrintSet 5, choose Files > Add Printer, then Serial Port/Virtual COM and the active port.

Honeywell advises keeping the Composite class whenever possible, as it is the most flexible.

Short answer: Insert the battery, plug the Honeywell power supply into the printer’s socket, then into the mains. Before first use, Honeywell asks for a charge of at least 4 hours, as batteries are shipped partially charged.

Caution: Honeywell sets the maximum charging temperature at 40 °C with its power supply. Use Honeywell batteries and power supplies, and check that all components are dry before inserting the battery.

Official charging procedure

1. Align the battery release tab on the same side as the charging contacts, then push the battery in until it clicks.
2. Connect the power supply to the printer’s power socket (Honeywell power supply, 12 V DC and 1.66 A minimum).
3. Plug the mains cord into the power supply, then into a socket.
4. Watch the battery light until it turns solid green.

Operating the printer while it is connected to the mains can shorten battery life: Honeywell does not recommend it. The quick start guide associates solid green with a charge of 90% or more, the user guide with 100%. The RP Series accessories guide lists spare batteries, 4-bay charging stations and a 4-bay battery charger.

Short answer: Three short beeps and a battery light flashing red indicate a critical or missing battery. Recharge the battery or fit a charged Honeywell battery.

Likely cause

According to Honeywell, when not charging, the battery light flashes orange between 10 and 30% charge and red at 10% or less. The 3 short beeps indicate a low battery or no battery.

Caution: Use only Honeywell lithium-ion batteries: according to the guide, replacing the battery with an incorrect type presents a risk of explosion.

What to do

1. Check that the battery is properly inserted and locked (the latch clicks).
2. Connect the Honeywell power supply to recharge, or replace the battery with a charged one.
3. During a swap, the printer can remain without a battery for at least 20 seconds without losing its connection or restarting.

Short answer: When the battery reaches a low level, the printer stops printing and queues the jobs. Replace or recharge the battery without delay: according to Honeywell, if the supercapacitor runs down first, the pending jobs are lost.

Likely cause

Battery too low. The Honeywell troubleshooting table also cites this case when the printer does not print and does not feed the paper.

What to do

1. Remove the discharged battery and fit a charged one: the printer then prints the pending jobs.
2. Or connect the Honeywell power supply and wait for the battery light to turn solid green.

Short answer: Briefly press the TEST button on the battery: the Test light shows its state of health. Held for more than 5 seconds, the same button lights the gauge of four green lights that shows the remaining charge.

Likely cause

The RP2f/RP4f guide links the light colour to the number of cycles: green from 1 to 400, orange from 400 to 500, red from 500 to 999. The Honeywell white paper on batteries states that a lithium-ion battery generally lasts 300 to 500 full cycles and should be replaced about every two years.

Caution: If a battery swells, heats up, smokes or gives off an odour while charging, Honeywell asks you to leave the area and alert the safety staff. Never puncture, crush or disassemble a battery; insulate the terminals of used batteries with adhesive tape before recycling them.

What to do

1. Press the TEST button on the battery once quickly to read its state of health.
2. Hold the TEST button for more than 5 seconds to display the remaining charge.
3. The battery status (remaining percentage, health, temperature) can also be read on the printer’s web page: System Information, then Statistics > Supply.
4. According to the Honeywell white paper, replace the battery if its health falls below 70%, if battery life drops noticeably, if it is deformed, swollen or discoloured, if its surface exceeds 60 °C or if it has been in service for more than two years.

The white paper also advises recharging from 30%, avoiding going below 10% and storing batteries at between 30 and 50% charge.
