Question: I have a Cannon MP560 that kept having communications errors. One of the suggestions I read was to remove the printer from the print & scan menu and re-add it. Once I did that the scanner disappeared as well and I cannot get OSX 10.7 to recognize this device as a scanner again. 

* Does anybody know how I can get OSX to recognize this device as a scanner again?

Here are some screenshots of my print & scan screen and my add printer dialogue. Bonjour does not show me any information about this device either.

Answer: 
Canon has updated most of their software (Easy-PhotoPrintEX, MP Navigator) and their drivers (printer, scanner) around the time when Lion came out. Make sure that you have the latest drivers installed.

You can download all the Canon software for your MP560 Scanner **[here](http://www.usa.canon.com/cusa/macosx_lion/multifunction_printers/pixma_mp_series/pixma_mp560#DriversAndSoftware)**.

Also, be sure to connect your printer via cable in order to use it as a scanner:

How to scan wirelessly: if anyone is still interested in using their MP560 scanner wirelessly on OSX Mavericks, I successfully used *Image Capture* from Applications.

Note the printer must be installed and recognized as a wireless printer - the MP560 will show up twice. Initially I had to install the MP560 via USB cable.
