I've had this printer about a year and a half and it's worked well. About a week ago the door malfunctioned, but I can get around that. See https://community.usa.canon.com/t5/Personal-Printers/iP-7200-printer-door-malfunction/m-p/280399#M17688
Then today it wouldn't print anymore and the power and orange alarm lights flash alternately. I followed the manual but could not clear it. All it tells me is "If the problem is not resolved, contact the service center". Does anyone here have a solution?
