Can't scan but can print with Canon PIXMA MG5500 I have a Canon PIXMA MG5500 and a MacBook Pro with OS X 10.10.3 

The printer and scanner are supposed to be wireless and I have no problems with the printer but when I try to use the scanner it just won't cooperate. 

I have tried everything. I've uninstalled the drivers and reinstalled them, I've tried looking for answers in the manual and nothing. 

When you want to scan something the scanner says I need to set my computer to scan. When I do that my computer can't find the scanner even though the connection is fine and sometimes it asks me to connect it with a USB cable which I don't have and it didn't follow the printer.
The packaging for the Pixma printers is misleading. It's a wireless printer, but for scanning, you need to either tether to your computer, or plug a USB drive into the printer. When conducting the scan, you'll be prompted to choose the USB drive, and after scans are complete, you can walk the USB to your computer.
