  2. Gently clean the encoder strip with a lint-free cloth dampened with isopropyl alcohol.
  3. Ensure there are no paper scraps in the carriage path.
  4. Power up and test the carriage movement.

Prevention and Maintenance

Keep your printing environment clean. Dust build-up on the encoder strip is a common cause of this failure. Always use genuine 502 ink to prevent internal sensor contamination.

When to Call a Technician

If cleaning fails, the encoder strip may be physically scratched or the sensor itself might be damaged, which requires professional servicing.
