Solutions

Quick Diagnosis

If the printer prints your label but displays E-03 before cutting, the issue is exclusively in the cutting path. Visually inspect the exit slot.

Step-by-step Solution

  1. Remove the tape from the machine.
  2. Clean the output slot using a dry brush to remove stuck adhesive pieces.
  3. Cycle the power to see if the cutter initializes correctly.
  4. Check for obstructions again if the error persists.

Prevention and Maintenance

Do not cut beyond the recommended media thickness. Clean the cutter area with a dry cloth periodically.

When to call a technician

If the cutter refuses to move and emits an electrical clicking sound, the cutting solenoid has failed.
