My printer went from "excellent" to "crap" in the blink of an eye. Copies suddenly began having a very thin annoying white streak from top to bottom on front and back. This printer is so seldom used that I haven't had to replace any of the colored toner cartridges yet, however, I am on the 2nd black toner cartridge. Unfortunately, it is apparently just out of warranty. If this happened 10 years down the road I would find it reasonable to chalk it off to age and "wear and tear". The Canon service rep lady referred me to a repair shop 90 miles away in Oskaloosa, Iowa. Turns out they haven't serviced Canon products for quite a few years. My next call to Canon connected me with a tech who was very kind and sympathetic but was of no help. He referred me to the next nearest service center which is a 4 hour road trip from here. Shipping alone would be comparable to the cost of replacing the printer. I about fell off my chair when he said "Sorry but there's nothing more I can do for you". Then he offered to connect me with someone who could help me upgrade to another Canon model. Yea I understand that nothing lasts forever, but this is hardly in that category. Goodbye Canon. I'm going back to my 12-year-old HP All-In-One that is an ink-eater but dependable. I hope you folks out there don't make the same mistake that I did by thinking a Canon laser printer is an "upgrade".
