Honeywell PM40 Plus II error ERR-4005: Sensor failure

The Honeywell PM40 Plus II error ERR-4005 occurs when the printer fails to register label gaps. It prevents incorrect printing by pausing the operation until the sensor can successfully track the media position.

Common causes

  • 1Misaligned labels.
  • 2Dirty sensor surface.
  • 3Incorrect calibration.
  • 4Unsupported material type.

Solutions

Quick diagnosis

If the printer reports ERR-4005, the sensor is likely struggling to distinguish the gap between labels.

Step-by-step solution

  1. Ensure labels are correctly aligned with the sensor.
  2. Run a media calibration from the settings menu.
  3. Remove adhesive residue from the sensor path.
  4. Change detection mode (Gap vs. Mark) if necessary.

Prevention and maintenance

Clean the sensor regularly and use high-quality labels to prevent debris build-up.

When to call a technician

If calibration continues to fail with a clean sensor, contact professional support.

Frequently asked questions

The printer failed to detect a label gap or black mark, usually due to misalignment.

No, it prevents misprints and media waste.

Labels must meet specific opacity standards for reliable detection.

Ideally, clean the sensor path during every label roll change.
