imageCLASS MF4450 MF toolbox can't find scanner

[chris_2000]

My MF4450 scanner worked 3 days ago, but it stopped funtioning today after my windows 10 pro recent patch, I guess. MF toolbox 4.9 can't connect to the scanner, with error msg" a supported scanner is not installed". The most funny part is windows fax & scanner can scan via this scanner. I connected the scanner to my PC directly via USB. Any solution?

Regards,

Chris.

Fantastic! Thanks for your help. No idea why MF Toolbox should stop working after 2 years of no problems, but after wasting about 5 hours reinstalling drivers etc I came accross your post which solved the problem in seconds. 

Thank you!

Please help: My mf toolbox 4.9 that I have used with my Canon imageclass 216n printer suddenly won't work. It's worked with Windows 10 but not now. I have uninstalled the software to no avail. I have installed the latest driver software for the computer, but that's not worked either. I have reinstalled the toolbox software, but no luck. The printer connected by USB does work.

Hi,

This solution works partially for me: I can scan from MF Toolbox, bo I can't scan directrly from Canon device (I do it very often). I get message that MF Toolbox used by my scaner might not be installed on my computer.

Do you have any ideas how to fix it?

Hi, I do have a MF8500C series and it can print but will not scane. I I deleted and re downloaded the Canon MF Toolbox 4.9, but it keeps giving me an message "There is no scanner connected. Please select a scanner". I can print from the same computer to the same printer. Other computers in the office is working fine. Just this one computer is giving this message. I tried your saggestion to run as admin and still didn't work. What els can I do?

Hi patriotmedical!

I will be glad to assist you.

The first thing to confirm is that the printer is selected in the MF Network Scanner Selector. Please follow the steps below:

1. Click in the system tray.

2. Select the check box for the machine, and click [OK].

• (NOTE) Up to ten computers can be connected at a time on a network to one product (scanner).

 If this does not resolve the issue, then it is recommended that you uninstall and reinstall the drivers and MF Toolbox software, following the steps at the link below:

Windows 8, 8.1, and 10 Scanning for imageCLASS
