My MG5320 was working fine for over a year, now it doesn't print at all. When I send a print job, the printer goes through all the motions, sounds like it's printing, and ejects the paper, but it's blank. I've put in new cartridges (a few times), run the nozzle clean and deep clean but none of that helps. Have downlaoded and installed the latest drive,  removed and cleaned the print head (using distilled water) and still no printing.

I've hooked it up via usb connection to three different computers (Mac, Win 7, Win XP) and it behaves the same. It scans OK just doesn't print. There's no error code.

Any idea what is going on?
