Quick Diagnosis

The E-004 code is a physical cutter jam. If the receipt is caught in the exit gate or crumpled, the cutter is stuck mid-operation.

  1. Power off the printer and disconnect from power.
  2. Press the release lever to open the top cover.
  3. Clear any jammed paper from the cutter blades area.
  4. Check the platen roller for adhesive buildup.
  5. Close the cover securely until it clicks.
