My Canon MP628 scanner suddenly stopped communicating with my desktop computer and my Sony Vaio laptop, however it still communicates with my Lenovo X1 laptop. As far as I know the only changes to my systems have been the regular Windows updates.

The printer functions work but not the scanner. I have tried reloading drivers on the Sony Vaio, but this did not restore the scanner functions, which work fine on my Lenovo.

Error or message just says that the scanner is off or disconnected from the network, however Windows device manager has no problem detecting the scanner as an imaging device on either desktop or laptop!

I am at a complete loss as to the cause, and the fact that the scanner works fine on one system but not the other two is completely mystifying!

The Desktop is running Win 10 Home 32bit, both laptops are running Win 10 Pro 64bit.
