I have a Color ImageCLASS MF656Cdw. When I try to print using Canon MF Scan Utility (from Windows 11), using Scan Now, Document, the printer scans, and after several seconds I get a ScanGear MF Cannot communicate with the scanner. The cable my be disconnected, or the scanner may be turned off. Check the scanner status and try again. Scanner driver will be terminated. Code : 155,0,0
Obviously the cable not disconnected, and the scanner isn't turned off, since the scanner worked after I gave it the command from my computer. I am connected by USB, and the device prints just fine when i send it print jobs from my computer.
Solved! Go to Solution.

I think you may have a problem with Windows Image Acquisition Service. If tis is not enabled your scanner will not work properly.
To enable the WIA service, follow these steps:
Windows + R on your keyboard.Access Services
services.msc and press Enter. This will open the Services window.Locate the WIA Service
Start or Restart the Service

WIA was running, but I went ahead and restarted it. Tried scanning, and it worked just fine. So either that fixed it or it's an intermittent issue. Thank you.
