Cannot communicate with scanner. Cable may be disconnected or scanner may be turned off...I

[MF6590]

I have a MF6590 mutifunction printer.  It had been working fine until last week when I got the error message "Cannot communicate with scanner.." I tried uninstall and reinstall te driver, I tried switching to a different USB port, reboot my PC, turned on/off the printer.. hopped on one foot...nothing worked.  Anyone has any suggestion?

Uninstall fails because it implies Toolbox is not installed.

Install fails but if any reason given it is gone before I can read it. There doesn't appear to be any difference in behaviour between Safe Mode and normal mode.

No difference except to the successfully removed Toolbox

I had the same problem with Windows 7 64 bits and Canoscan 8400F - french version. I've got the message "Impossible de communiquer avec le scanner. Le câble est peut-être déconnecté..." (I put the sentence in french for search bots).

My solution:

I installed last drivers from Canon

I went to system management, checked for installed material - found my Canonscan 8400F installed with no alert message (yellow circle). I right click on it and asked for update to last drivers. And Windows installed "new" drivers that work ! Don't know where they come from but it works for me.

The problem occured again. The preview scan begins and stops. An error message was showing "Cannot communicate with scanner".

It was strange because the scanner works on a another computer. I was asking myself what could block the scan and desactivated Antivir. It seems it did the trick. Everything works correctly now. So you may do the test.

After upgrading from Windows 7 to Windows 10, I have been able to install Toolbox and the scanner works normally.

Having the same issue, but I have a canoscan 8400f attach to a Mac 10.9.5. It has been working all these years and today it just won't connect or communicate. Have turned on and off the scanner. Rebooted the computer and still nothing. Hope anyone can help.
