Error Err-05-Temp Honeywell PM45: Troubleshooting Guide

The Honeywell PM45 RFID Enterprise error Err-05-Temp is a protection signal activated when the printhead exceeds thermal operating limits. This error halts printing to prevent permanent damage to the printhead's heating element. It mostly occurs due to an excessively high heat (darkness) setting or poor ambient heat dissipation.

Common causes

  • 1Darkness setting too high for the ribbon used.
  • 2Continuous use without cooling cycles in hot environments.
  • 3Internal fan blocked by accumulated dust.
  • 4Printhead thermistor failure.

Solutions

Quick Diagnosis

If you perform long runs of hundreds of labels without pause, the printer likely reaches its thermal limit. Determining if the Err-05-Temp error occurs shortly after startup (suggesting a faulty sensor) or after hours of use (suggesting poor dissipation) is the key to solving the issue.

Step-by-Step Solution

  1. Turn off the printer and open the cover to let trapped heat escape.
  2. Reduce the printing 'darkness' in the driver settings by 5 to 10 units.
  3. Verify that the printer's rear fan is spinning and free of dust.
  4. If the error reappears, check that the print cycles have periodic pauses.

Prevention and Maintenance

Do not place the printer near machinery that generates heat. Regularly clean the printhead with isopropyl alcohol so it transfers heat efficiently, preventing the printer from working harder than necessary.

When to Call a Technician

If the alert appears instantly when starting the device without having printed, the printhead temperature sensor might be short-circuited and requires a printhead change or professional repair.

Steps to follow

  1. 1

    Printing Pause

    Stop printing for 20 minutes to allow the printhead to cool down naturally.

  2. 2

    Environment Check

    Ensure the printer is not in an enclosed area or near intense heat sources.

  3. 3

    Heat Adjustment

    Reduce the 'darkness' or 'heat' setting in the print driver if it is set too high.

Frequently asked questions

This error indicates that the printhead has exceeded the safe operating temperature threshold, triggering a safety shutdown.

Yes, intensive use without pauses, especially at high speed and darkness, tends to raise printhead temperature.

Always use Honeywell ribbons that require the least amount of heat possible to transfer the image clearly.

Yes, accumulated dust prevents heat dissipation; regularly clean internal components.
