I have a PIXMA MX522 printer/scanner. The scanner stopped working. My computer is a MacBook Pro. I recently upgraded to OS X El Capitan. The scanner worked once and then has stopped. "My image garden" was where my previous scanned documents came up. Now it prompts me to select scanner on Canon IJ Network Scanner Selector EX but doesn't allow me to choose the MX520 series.
Any suggestions? Thanks
