  • 1Dust buildup on the sensor lens.
  • 2Paper scraps lodged in the feed path.
  • 3Sensor failure due to electrical surge.
  • 4Misaligned guide rail.

Solutions

Diagnostic

If the E004 error appears immediately upon powering on with an empty input tray, the optical sensor is likely obstructed by dust.

Step-by-step resolution

  1. Power off the device and open the main cover.
  2. Locate the paper detection sensors within the guides.
  3. Use short bursts of compressed air to clean them.
  4. Use a dry cotton swab if there's visible residue.

Prevention and maintenance

Regularly use a soft brush to remove dust. Never spray cleaning liquids directly into the sensors.

When to call a technician

If deep cleaning does not resolve the error, the optical sensor unit itself may have failed and requires a technician's replacement.
