Honeywell PM45 and PM45c troubleshooting guide: errors, faults and fixes

Short answer: According to Honeywell, the red Media icon signals media that is out, jammed or loaded incorrectly. Reload the roll following the quick start guide, then run a smart calibration by holding down the Print button with the printer ready.

Likely cause

The PM45, PM45c and PM65 quick start guide cites three cases for the red Media icon: out of media, media jammed or media loaded incorrectly. When off, it indicates that media is available and loaded correctly.

Caution: Keep your fingers out of the print mechanism when the printer is powered on (Honeywell safety instruction).

What to do

1. Open the cover and lift the printhead with its lever.
2. Check that the roll is in place on the media hanger and that the media is not jammed in the mechanism; reload it following the illustrations in the quick start guide.
3. The gap sensor is positioned using its adjustment knob, inside the printer.
4. Lower the printhead, close the cover, then hold down the Print button in the ready state to run a smart calibration (see calibration).
5. In an error state, pressing Print feeds the media: check that it advances normally.

The optional rotating roll holder (Rotation Hanger) adds paper-out detection; Honeywell reserves its installation for an authorised service technician.

Short answer: The red Ribbon icon indicates a ribbon that is out, not advancing or loaded incorrectly: reload the ribbon. When off, it means that the ribbon is fine or that the printer is not configured to use a ribbon.

Likely cause

The quick start guide cites three cases: ribbon out, ribbon not advancing, ribbon loaded incorrectly. According to the Honeywell product page, the PM45 accepts ribbons on a 1-inch core, with the ink on the inside or on the outside. The data sheet gives a ribbon roll of up to 80 mm in diameter and 450 m on the PM45, 61 mm and 229 m on the PM45c.

Caution: Keep your fingers out of the print mechanism when the printer is powered on (Honeywell safety instruction).

What to do

1. Open the cover and lift the printhead.
2. Check that there is ribbon left on the supply hub and that the ribbon is properly attached to the take-up hub.
3. Reload the ribbon following the illustrations in the quick start guide; the fifth loading step only applies to the PM65.
4. Lower the printhead and close the cover.

Short answer: The printhead is lifted. Lower it with its lever: according to Honeywell, the icon goes out when the printhead is lowered.

Likely cause

The quick start guide associates the red icon with a lifted printhead and the icon off with a lowered printhead. The printhead is lifted by turning its lever anticlockwise (accessories guide).

Caution: Keep your fingers out of the print mechanism when the printer is powered on (Honeywell safety instruction).

What to do

1. Open the media cover.
2. Check that the media and the ribbon pass correctly under the printhead.
3. Turn the printhead lever to lower the printhead, then close the cover.

At start-up, with the printhead lifted, pressing the Print button restores the default settings: do not press Print when turning on the printer with the printhead open, unless that is what you want (see default settings).

Short answer: According to Honeywell, the red Printhead Hot icon signals that the printhead is too hot: let it cool down. When off, it indicates a normal temperature and a printer ready to print.

Likely cause

The quick start guide associates the red icon with a printhead that is too hot. It also uses the last two icons, Printhead Hot and Maintenance, lighting up together as the cue at start-up for printing the test label.

Caution: Keep your fingers out of the print mechanism when the printer is powered on (Honeywell safety instruction).

What to do

1. Let the printhead cool down before resuming printing.
2. Do not put your fingers into the print mechanism while the printer is powered on.
3. If the icon lights up together with the Maintenance icon just after power-on, this is the cue provided for the test label (see test label).

Short answer: Honeywell indicates a printer configuration problem. Check the settings with a Honeywell configuration tool (web interface, PrintSet 5 or PrintSet MC); as a last resort, the default settings can be restored from the Print button.

Likely cause

The quick start guide does not specify the setting at fault: the red icon signals a configuration problem, the icon off means there is no problem. The PM45 and PM65 data sheet cites PrintSet 5, the web interface and PrintSet MC for Android and iOS as management tools.

What to do

1. Open the printer's web interface or PrintSet to check the settings.
2. If the configuration cannot be corrected, restore the default settings: with the printhead lifted, press Print during start-up (see default settings).
3. If the icon stays red, consult the Honeywell knowledge base and technical support portal (honeywell.com/PSStechnicalsupport), given in the quick start guide.

Short answer: According to Honeywell, the General Error icon signals a problem that does not match any other icon. In an error state, pressing Print feeds the media; if the icon stays red, contact Honeywell technical support.

Likely cause

The quick start guide reserves this icon for problems not covered by the Media, Ribbon, Printhead Hot, Printhead Lifted and Printer Configuration icons, without detailing their causes.

What to do

1. Check that no other red icon is lit: it would point you to a more specific entry.
2. Press the Print button: in an error state, it feeds the media.
3. If the icon stays red, consult the Honeywell knowledge base or technical support portal (honeywell.com/PSStechnicalsupport); for a repair, a return number (RMA) can be requested on automation.honeywell.com, in the Support section.

When to call a technician: if the General Error icon stays red, the Honeywell documentation directs you to its technical support and then, for a repair, to a service centre with an RMA number.

Short answer: The amber Maintenance icon indicates that maintenance is needed: a lifetime counter (lifetime odometer) threshold has been reached. It stays off as long as no maintenance is required.

Likely cause

The quick start guide associates the amber icon with maintenance being required and a lifetime counter setting being reached. It does not specify which maintenance corresponds to which threshold.

What to do

1. Identify the maintenance set for the counter setting that has been reached.
2. Print a test label to check the print condition (see test label).
3. If the printhead is the cause, replace it (see printhead replacement).

Just after power-on, the Printhead Hot and Maintenance icons lit together serve as the cue for printing the test label.

Short answer: The white Pause icon indicates that the printer is paused. Press the Print button to resume printing. Pressing Print during printing stops or pauses the printer after the current label.

Likely cause

According to the quick start guide, pressing Print during printing stops or pauses the printer, which first finishes the current label.

What to do

1. Press the Print button once: in the Paused state, it restarts printing.
2. Check that the Pause icon goes out.

The Print button changes role depending on the state: at start-up, it opens calibration mode (or restores the default settings with the printhead lifted); in the ready state, it feeds the media, and a long press starts smart calibration; during printing, it pauses; in an error state, it feeds the media.

Short answer: These errors come from the applicator connected to the applicator interface card: the printer has received an error signal from the applicator (AppErr1, AppErr2 or AppErr3) or the external RTW signal. Look for the cause on the applicator side.

Likely cause

According to the Honeywell interface cards guide, the AppErr1 to AppErr3 inputs are reserved for the applicator to signal its own errors, and the RtW_in_Ext input synchronises the printer with the applicator's status. Each signal detected triggers an event in the System Health Monitor (SHM). The input signals are active low.

What to do

1. Identify the error by its number: 1340, 1341 or 1342 for AppErr1, AppErr2 or AppErr3, and 1343 for the external RTW signal.
2. Look for the cause on the applicator: the printer only reads the error state that it transmits.
3. In Direct Protocol, the firmware handles all the signals and enables the SHM events; in Fingerprint, the error inputs are linked to subroutines with the ON PORTIN command.

The message “RTW Extenal Error.” is reproduced with the spelling used in the Honeywell guide. The applicator interface card, reserved for the PM45 according to the PM45/PM45c data sheet, requires Fingerprint firmware v10.18.00.0015 or later and works in Fingerprint, Direct Protocol and ZSim.

Short answer: “APPLICATOR PORT: Wait for signal.” is not a fault: the printer is waiting for the print start signal from the applicator. The “Operation not allowed” and “Dataready not enabled.” messages signal a command that is incompatible with the state of the applicator port or with the language used.

Likely cause

According to the Honeywell interface cards guide, these messages appear with the applicator interface card when a PRINTFEED command is waiting for a signal, or when a program sends a command that the applicator port configuration or the language (Direct Protocol) does not allow.

What to do

1. “Wait for signal.”: PRINTFEED is waiting for the startprint signal. “Wait for reprint.”: a PRINTFEED -1,1 command is waiting for the reprint signal. These messages appear after a few seconds of waiting.
2. Error 88: an applicator port command was sent while this port is disabled; enable the port or stop sending these commands.
3. Error 89: PORTOUT(PORT) ON or OFF was executed on a port used by the applicator while the applicator port is enabled; avoid this command on these ports.
4. Error 90: PORTOUT.DATAREADY ON/OFF and PORTIN.<SIGNAL> GOSUB are not available in Direct Protocol.
5. Error 1344: in Fingerprint, with the applicator port enabled in I-Style or Z-Style, enable dataready before PRINTFEED, otherwise the command stops without printing.
6. To enable and set up the applicator port: on the web page, System Settings > Manage I/O, then Configure > Printing > Applicator; on the touch display, Menu > Settings > System Settings > Manage I/O, then Menu > Settings > Printing > Applicator.

Three modes are available: Z-Style, S-Style and I-Style; I-Style adds to the Z-Style or S-Style settings the triggering of external inputs/outputs through the External Error port.

Short answer: 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.

Likely cause

The PM45, PM45c and PM65 quick start guide describes two ways of accessing calibration with the Print button. According to the data sheet, the PM45 detects gap, notch, black mark and continuous media, as well as media low and media out.

Caution: Keep your fingers out of the print mechanism when the printer is powered on (Honeywell safety instruction).

Official calibration procedure

1. Load the media and, for thermal transfer, the ribbon, then lower the printhead and close the cover.
2. The gap sensor is positioned using its adjustment knob (gap sensor adjustment wheel), inside the printer.
3. With the printer in the ready state: hold down the Print button to start smart calibration.
4. Alternative method: press Print during start-up to enter calibration mode.
5. Print a test label to check the result (see test label).

With the printhead lifted, pressing Print at start-up restores the default settings instead of entering calibration (see default settings).

Short answer: Put the arm edge guide back in place after loading. For large rolls, Honeywell offers a large edge guide (Large Media Edge Arm Guide) that stops the roll from shifting.

Likely cause

According to the PM45/PM45c accessories catalogue, the arm edge guide (Media Arm Edge Guide) stops the roll from telescoping. The accessories guide specifies that the large guide stops large rolls from shifting sideways.

What to do

1. To load a roll, slide the edge guide to the end of the arm and turn it 90° clockwise; once the roll is in place, straighten the guide.
2. To fit the large guide: with the guide at the end of the arm and turned 90°, slide a Torx screwdriver between the arm and the guide, then turn anticlockwise to remove the small guide.
3. Press the large guide onto the arm and straighten it into position.

According to the data sheet, the label roll can be up to 213 mm in diameter, 152 mm on PM45c models with a long door.

Short answer: Honeywell requires Fingerprint firmware v10.18.00.0015 or later, and the card only works in Fingerprint or Direct Protocol, not with IPL firmware. For RS-422 or RS-485, a driver circuit sold separately and a jumper setting are required.

Likely cause

According to the interface cards guide, the industrial card provides eight digital inputs/outputs, four relays and an RS-232/422/485 port, addressed as uart2 in Fingerprint. Non-isolated RS-232 is ready to use; isolated RS-422 and RS-485 require circuit 360-027-001 (RS-422) or 360-026-001 (RS-485) and setting the jumpers. The PM45/PM45c data sheet reserves this card for the PM45 and excludes it with IPL firmware.

Caution: Turn the printer off before installation and protect the card from static electricity (ESD precautions).

What to do

1. Check the firmware version: Fingerprint v10.18.00.0015 or later.
2. Check the language: the card only works in Fingerprint or Direct Protocol.
3. For RS-422 or RS-485, have the corresponding driver circuit fitted and the jumpers set; the circuit must not be fitted the wrong way round.
4. Jumper P3:2-3 supplies the port with +5 V DC, but removes the galvanic isolation.
5. Respect the electrical limits: opto inputs in the high state between 10 and 40 V (24 V typical); relays limited to 1 A, 100 VA and 100 V AC.

When to call a technician: Honeywell reserves the installation of the industrial interface card for an authorised service technician.

For new applications, Honeywell recommends the local area network rather than RS-485, which requires a special protocol and dedicated cabling limited to 1,200 m.

Short answer: The standard cutter cuts labels up to 10.4 mils (0.26 mm) thick. Honeywell reserves its installation for an authorised service technician, and the kit differs between the PM45 and the PM45c.

Likely cause

The accessories guide describes two installations: on the PM45, the cutter cable connects on the media side; on the PM45c, it connects to the main logic board, passing behind the user interface cover. The accessories catalogue lists one cutter kit per model.

Caution: Fitting is carried out with the printer off, the power cord and communication cables disconnected, following the precautions against electrostatic discharge.

What to do

1. Check that the thickness of your labels does not exceed 0.26 mm.
2. Order the cutter kit for your model, PM45 or PM45c.
3. Have the cutter installed by an authorised technician.
4. Once the cutter is fitted, pass the media through the cutter before closing the printhead and the cover.

When to call a technician: Honeywell reserves the installation of the cutter for an authorised service technician.
