  1. Unplug the device: Safety first; disconnect the power cable.
  2. Visual check: Open the top cover and check the rails for paper scraps.
  3. Manual test: Gently move the carriage from side to side; it should slide smoothly without resistance.
  4. Sensor cleaning: Use a dry, lint-free cloth to gently wipe the transparent strip near the rail.
  5. Reset: Reconnect the power and restart the device.
