What to do if Canon Copier shows E402 error?
- SsamuelcabreraAug 11, 2025
If your Canon Copier displays the error code E402, it could be due to several reasons. First, check the wiring from the feed motor clock sensor to the ADF controller PCB. If the wiring is normal, replace the feed motor clock sensor. Also, inspect the gear and belt for any damage. Another potential cause is the feed motor itself, so check its wiring to the ADF controller PCB; if the wiring is okay, replace the feed motor. If none of these steps resolve the issue, consider replacing the ADF controller PCB.
