Canon PIXMA MX712 worked great, no degradation in print quality (over last 1.5 years). Suddenly won't print or copy anything. Can't print wirelessly (from IPAd or computer) or plugged in with USB directly to laptop. Can't copy. Makes normal print head sounds and "prepares" to print. Sounds like it is working and spits out nothing but blank pages. Tried doing test print and nothing shows up on page. Tried doing a deep clean and still nothing. Tried unplugging and letting it reset and turn back on and still nothing. Tried switching out printer cartridges and still nothing. All lights are on for the print cartridges. The printer says it is ready and never received a print error. Please help me stop getting nothing but blank pages. It would seem normal to start having streaking or blotchy prints, but not just to work great one day and then stop.
