Pixma MP240 gives message 'failed to open a connection to the device (-21345)

Hello!

my Pixma MP240 gives message 'failed to open a connection to the device (-21345) when attempting to scan. This printer/scanner has worked well for many years, but will not scan (still prints fine) now that I have upgraded to a new mac running Monterey 12.0.1. This printer/scanner is NOT wifi equipped, I just use a USB cable.

Any ideas on a fix?
