Hi,
iX6820 purchased October 2018. It's only a few months out of warranty. Light use. Color text documents, 11x17 printing on plain paper.
This morning I received error code A861 and the alarm light was flashing. I called tech support and went through some simple steps only to be told there's likely a mechanical issue with the printer and I should buy a new one. I then was transferred to Canon sales where I was offered a replacement discount for $143.99 + tax + shipping. I mentioned another online vendor had a better price and they offered to price match only after I pointed that out.
I had a technically-oriented friend look at the printer just to see if it could revived and they mentioned there was a problem with the ink tray being out-of-whack in its track and would cost more to fix than buy another one.
Disappointed Canon. Ink is already a rip off and having to buy a printer after a year of use is theft in my view. Your Printer division should learn from your Camera Lens division and try making something that lasts.
