Hello there! In my office we have 4 Canon MF445dw printers which are around two years old each. Three of them are starting to have same weird fault which I couldn't solve. When copying or scanning duplex the scanner on the adf side is scanning around half of page pitch black...anyone has some idea about what the problem might be? I opened on one printer the adf cover, just to see that all electric connections are perfectly fine and all seems alright on the adf. After reassembling the printer started scanning perfectly fine but after a day the problem came back...so anyone with some ideas to solve the problem?
The issue sounds like a hardware issue with the scanner, there is a loose connection or a problem with the scanner element. In this situation, I would suggest contacting support over the phone at 1-800-652-2666 or logging into your MyCanon account to check your available service options.
