Common causes

  • 1Excessive adhesive buildup on the label media path.
  • 2Blocked or misaligned platen roller.
  • 3Printhead pressure setting too high for media.
  • 4Electronic failure in the motor controller board.

Solutions

Quick Diagnostics

The F-CODE-02 suggests the main motor is working harder than usual. If your printer stops and shows this, there is almost certainly a mechanical blockage in the label path.

Step-by-step Solution

  1. Cleaning: Remove media and clean adhesive remnants from rollers.
  2. Inspection: Verify the platen roller has no cracks or obstructions.
  3. Manual Check: Rotate rollers by hand to ensure there is no mechanical resistance.
  4. Restart: Perform a full restart of the device.

Maintenance and Prevention

Use quality labels to prevent adhesive bleed. Clean sensors and rollers at every media change.

When to Call a Technician

If the motor makes a grinding noise, bearings likely require lubrication or professional replacement.
