Solutions

Quick Diagnosis

If the error persists, open the printer and check if the ribbon is moving as the printhead tries to feed.

Step-by-step Solution

  1. Rewind: Ensure the ribbon is tightly wound on the take-up spindle.
  2. Tension: Adjust the ribbon tension so it remains taut during feed.
  3. Cleaning: Check for any ribbon scraps near the rotation sensor.

Prevention and Maintenance

Keep ribbons away from heat. Use compatible mandrels to avoid spool wobble.

When to Call a Technician

If the ribbon moves but the sensor fails to register, the encoder module might need replacement.
