I've been having an annoying issue with my Canon Pixma MG6100 scanner: I'm unable to wirelessly scan directly to my iMac for the last few months. I can print wirelessly without a problem, but not scan. It wasn't this way when I bought the multifunction printer, but months ago this feature broke, I'm guessing after some update to OS X.
I've tried downloading a driver from Canon but it was for MG6200, I couldn't find one for the 6100. Anyways this driver is really an application sort of like the Printer/Scanner tool in Preferences, and it doesn't see the scanner either.
Any ideas?
