Honeywell PB50 error ERR-01: Troubleshooting

The Honeywell PB50 error ERR-01 is directly related to the system's inability to recognize the presence or type of thermal paper. If you are wondering why my Honeywell PB50 shows error ERR-01, it is likely that the thermal printhead is obstructed by residual adhesive or dust. This is a typical error in busy logistics environments.

Common causes

  • 1Adhesive buildup on paper sensors.
  • 2Thermal head dirty or burnt residue.
  • 3Misaligned black mark sensor.

Solutions

Quick Diagnosis

The ERR-01 error occurs when the printer cannot calibrate the top of the form (gap/mark). It manifests as the device stopping after an initial print attempt.

Step-by-Step Solution

  1. Turn off and open the media compartment.
  2. Clean the printhead with an alcohol cleaning pen specific to this model.
  3. Verify the alignment of the thermal paper relative to the sensor.
  4. Close the cover and press the 'Feed' button to perform a sensor calibration.

Prevention and Maintenance

Clean the printhead after every roll change. Always use certified thermal paper to prevent premature printhead wear caused by low-quality adhesives.

When to Call a Technician

If the error persists after physical cleaning and calibration, the printhead might have suffered a burn-out or a line of pixels has failed permanently.
