  2. Open the front access door and look for any jammed paper or debris.
  3. Manually slide the carriage side to side to feel for resistance.
  4. Wipe the guide rail with a clean, dry cloth to remove any sticky ink or residue.
  5. Close the door and power on the printer for auto-initialization.

Maintenance and Prevention

Regularly check the interior for paper dust. Avoid using non-standard media that could scrape the inside of the printer. Clean your heads through the maintenance menu monthly.
