Solutions

Quick Diagnosis

If the screen displays 404-PAPER, check the roll inside. If paper is present, debris is likely interfering with the detection signal.

Step-by-Step Solution

  1. Open the media door and remove the existing roll.
  2. Inspect the paper sensor at the base of the chamber.
  3. Clean the area with a dry, lint-free cloth or compressed air.
  4. Reload the roll, ensuring it slides through the guides correctly.

Prevention and Maintenance

Clean the printer's interior regularly to prevent paper dust buildup. Use high-quality paper to minimize chemical residue. Avoid forcing the lid.

When to Call a Technician

If the sensor remains unresponsive after a thorough cleaning, the component might need hardware replacement.
