Imageclass MF733cdw Scanner not connecting to computer

[cpratt43205]

I have an imageclass MF733cdw.  I have been using for months no, with no issues.  I am suddenly unable to scan to my computer.  I have read several posts regarding Windows 10 update causing the problem, however, the fixes I have read have not helped my problem.

I have Windows 10. 

Use imageclass MF733cdw through network connection.

I havde removed the device, removed all drivers, reinstalled drivers, both the factory disk and the newer version online but still fails to connect.  I have tried using Windows fax and scan utility, and it connects, but has horrendous results scanning (looks like a child used "White-Out" in half the document.

Additionally, I would prefer to use Canon scan utility over Microsoft as it allows me to scan from the printer itself, and I do not have to be at my keyboard.

Any help would be greatly appreciated!

Hi cpratt43205!

Since you are able to use the Windows Fax and Scan software, there may be a TWAIN driver conflict that is causing the issue with the MF Scan Utility. Please follow the steps at the link below to check for a conflict:

Move non-Canon TWAIN Files from the TWAIN_32 Folder

Please leave the MF730 Series and WIA.ds files in the folder. If you still experience an error, or need further assistance, please call us at 1-800-OK-CANON (652-2666), Monday - Friday 10:00 a.m. to 6:30 p.m. ET (excluding holidays).
