Canon imageCLASS D570 error E301: Diagnosis

The Canon imageCLASS D570 error E301 relates to the document scanner unit (CIS/CCD). The code triggers when the scanner sensor cannot complete its initial homing sequence. Why does my Canon imageCLASS D570 show error E301? It usually involves rail friction or a motor stall in the scan module.

Common causes

  • 1Stiff or dirty scan carriage guide rails.
  • 2Worn scanner transmission belt causing slip.
  • 3Home position sensor fault.
  • 4Accumulated debris under the scan lid interfering with carriage movement.

Solutions

Diagnóstico rápido

If the scanner carriage makes abnormal noises or stops moving when you attempt a copy or scan, the E301 is signaling a mechanical fail-safe. The unit halts operation to prevent motor burnout.

Solución paso a paso

  1. Check locking switch: Ensure the scanner transport lock (if applicable) is disengaged.
  2. Clean guide rails: Ensure there are no physical obstructions along the carriage travel path.
  3. Forced calibration: Turn off the printer for 60 seconds and restart it to trigger a fresh scanner motor calibration.

Prevención y mantenimiento

Keep the scan glass clean using only a dry or slightly water-dampened cloth. Never put heavy items on the lid, as sagging glass covers can misalign the carriage rails, leading to the E301 positioning error.

Cuándo llamar a un técnico

If the error persists after a reboot, the scanner belt or drive motor has likely reached end-of-life or been damaged. Professional service is necessary to replace the scanner assembly components without damaging the delicate ribbon cables or logic board connectors.

Frequently asked questions

The E301 error means the scanner carriage has failed its startup sequence, often due to physical resistance or a stepper motor fault.

If scanning or copying is required, yes. If you only print, the error may still disable your control panel, requiring attention.

Avoid placing heavy items on the scanner glass and ensure transport locks are active before moving the device.

No, but cleaning the glass regularly ensures the sensor works without extra strain on the motor.
