Solutions

Quick diagnosis

If you hear a clicking or tapping noise during startup, the scanner is trying to move but something is blocking it.

Step-by-step solution

  1. Lock: Check for a physical transport lock.
  2. Reset: Power off and unplug for 5 minutes.
  3. Test: Power on and watch if the scanner calibrates (moves side to side).
  4. Cleaning: Check for debris blocking the internal glass.

Prevention and maintenance

Never force the top cover. Clean the scanner glass with alcohol-free glass cleaner and a soft cloth to prevent optical sensor dust damage.

When to call a technician

If the carriage still makes noise and fails to calibrate, the motor or the drive belt might be broken.

Frequently asked questions

Ensure the transport lock is released and power cycle the printer.

No, it is an optical component, it only requires cleaning of the glass.

Most cases are resolved by a power cycle, but a broken motor needs professional service.
