bought a PIXMA TR4527 from Amazon. It failed to ever start and gave a buzzing sound and 3 messages: <support code 7600 repair needed> <contact service center. repair needed> and <turn the device off, unplug the power cord> .Called tech help they walked me thru some checks then gave up. Said return to seller. I had it over 30 days and can't return to Amazon (my bad). Canon USA states it is a Canadian model, shouldn't have been sold in USA, Not their problem and won't deal with it. Contacted Canada they won't deal with it because I'm in USA. Right now it it is a dead hulk. Any suggestions to trouble shoot it myself ? Hate to buy another ( and another brand) if this can possibly be salvaged
