Lost wireless scanner; wireless printer still there

[gowild2000]

Have a Canon MG5420 wireless printer/scanner. A few days ago, the scanner portion just disappeared and the MBA (2014) only sees the printer. I'm running Yosemite, have spoken to Apple support and no luck. Have downloaded the Canon drivers, reinstalled, fixed disk permissions, deleted everything relevant in the library folder, rebooted (x 20) reset the printer to factory defaults and still no luck. Anybody have a thought on what I might try next? The scanner is shared and used a lot so this hurts.

Try plugging it in (USB) and see if that resets something?

Tried that and the scanner appears when the device is plugged in via USB but disappears once it's unplugged. Thanks for the suggestion.

I've had a similar issue with my Epson all-in-one... a pain in the a@s driver issue.

Found out you don't need to use the printer driver or scanner app -

Look in your Apps and use 'image capture' app - this'll find your scanner wirelessly, and there you go. Scan to PDF or whatever.
