  1. Disconnect the power cord to safety stop the printer.
  2. Lift the scanner lid to access the print carriage.
  3. Remove any visible paper scraps, labels, or dust.
  4. Gently slide the carriage manually to ensure it moves smoothly.

Prevention and Maintenance

Use the recommended paper weight. Regularly clean the clear encoder strip with a dry, lint-free cloth. Always use genuine ink to prevent printhead clogging.
