Canon imageCLASS D570 error E100: Tech fix

The Canon imageCLASS D570 error E100 signals a critical issue with the Laser Scanning Unit (LSU). This fault prevents the beam from reaching the drum or indicates the rotating mirror motor is failing. Why does my Canon imageCLASS D570 show error E100? It is often triggered by optical obstruction or internal hardware faults.

Common causes

  • 1Rotating laser mirror motor failure.
  • 2Toner dust buildup on internal optical sensors.
  • 3Communication break between main logic board and laser unit.
  • 4Age-related laser diode output degradation.

Solutions

Diagnóstico rápido

The E100 locks up the printer entirely. If your device displays this code and remains stuck during initial startup, the main image processing laser component is not responding correctly.

Solución paso a paso

  1. Check cartridge: Remove the toner cartridge and ensure no stray toner powder is blocking the laser beam window.
  2. Clean laser glass: Use a dry, lint-free cloth to gently wipe the internal laser scanner glass.
  3. Power reset: Close all lids and restart the printer to allow the scanner unit to recalibrate.

Prevención y mantenimiento

Ensure the printer lid is always closed. Using high-quality genuine toner is the best preventative measure against this error, as it prevents toner debris from entering the laser unit's path and clouding the delicate optics.

Cuándo llamar a un técnico

If wiping the optical window does not clear the E100, the rotating mirror motor has likely failed. Professional repair is required; the laser assembly is a sealed unit, and improper service can lead to permanent damage or safety hazards from laser exposure.

Frequently asked questions

The E100 error indicates a failure in the Laser Scanning Unit (LSU), preventing the printer from correctly processing image data.

Cleaning the glass is feasible, but replacing the laser motor is complex and requires specialized tools to ensure proper optical alignment.

Yes, using original Canon 137 toner prevents excessive toner leakage which can contaminate the optical lenses.

Keep the unit away from dusty environments and avoid slamming doors, as impacts can misalign the laser assembly.
