Common causes

  • 1Media path obstruction by stray labels.
  • 2Adhesive buildup on platen roller.
  • 3Improperly adjusted guide rails.
  • 4Incompatible or thin-backed label stock.

Solutions

Quick Diagnosis

If the motor runs but the labels don't feed, a jam is present inside the cover. Open it to verify if labels are wrapped around the platen roller.

Step-by-Step Solution

  1. Open printhead: Use the side lever to lift the printhead and gain access to the path.
  2. Extract labels: Gently remove the jammed labels, being careful not to touch the sensors.
  3. Clean adhesive residue: Clean any sticky residue on the platen roller using isopropyl alcohol.

Prevention and Maintenance

Precise media guide adjustment is the best way to prevent jams. Clean the rollers monthly to avoid build-up that encourages labels to stick.

When to Call a Technician

If clearing the path and cleaning the rollers doesn't stop the jam alert, the media sensor may have become misaligned during a previous jam cleanup attempt.
