scanning with canon printer MG7150
I have just bought a Canon multifunction printer MG7150. I have an iMac running OS10.9.1. I can print over air-print, but cannot scan wirlessly. I get the error message 'An error occurred while communicating with the scanner.' I have tried turning everything on and off, reinstalling all the software and drivers and reselecting the printer. No luck. Has anyone else had this problem and solved it?
iMac, OS X Mavericks (10.9.1)
