Common causes

  • 1Incorrect alignment: labels poorly adjusted in side guides.
  • 2Adhesive residue: dirt on the roller preventing smooth feeding.
  • 3Dirty sensor: dust on the pass-through sensor blocking label detection.
  • 4Excessive tension: roll placed poorly with too much pressure.

Solutions

Quick Diagnosis

The Paper Jam error is identified when the panel light blinks red and the software reports a feed failure. If you see labels wrapped around the roller or the head, the cause is evident.

Step-by-Step Solution

  1. Lift the print head release lever to ease tension.
  2. Gently extract the jammed labels, avoiding sudden pulls that could damage sensors.
  3. Clean the drive roller with isopropyl alcohol to remove adhesive residue.
  4. Reload the paper, ensuring side guides are properly adjusted.

Prevention and Maintenance

Use labels with the correct width and ensure the media is centered. Clean the print head every time you change the roll to avoid dirt buildup that causes slipping. Deep roller cleaning is recommended at the end of every month of heavy use.

When to Call a Technician

If after cleaning sensors and recalibrating media the error persists, the pass-through sensor might be damaged or misaligned, requiring professional help.
