Honeywell RP4T II Mobile error err-head-overheat: Solution

The Honeywell RP4T II Mobile error err-head-overheat is triggered to prevent permanent damage to the printhead's thermal elements. It is very common after massive continuous printing under direct sunlight or in hot environments. Letting the unit rest is the most effective method.

Common causes

  • 1Excessive print cycles without pause.
  • 2High ambient temperature.
  • 3Print density set too high.
  • 4Dirt buildup on the head surface.

Solutions

Quick Diagnostics

The err-head-overheat error stops all printing functions. If the unit has been printing labels without pause, let it cool for at least 10 minutes.

Step-by-Step Solution

  1. Turn off the printer immediately.
  2. Move to a cool place away from direct sunlight.
  3. Open the cover to ventilate the thermal head.
  4. Wait until the temperature drops before restarting.

Prevention and Maintenance

Avoid setting the print density to maximum if unnecessary. Clean the printhead periodically to improve heat transfer.

When to Call a Technician

If the device reports overheating immediately after turning it on, the head's thermal sensor is faulty.
