  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.

  If your Canon Copier is showing the E400 or E712 error, you should first check the wiring for the power supplied to the copier. If the wiring is correct, the issue may be with the ADF controller PCB, in which case you should replace it. If the problem still occurs, try replacing the copier's image processor PCB.
