I had just printed a page on my MP495 perfectly. Next time I printed (just 5 minutes later) without having touched USB cable or anything, it printed a black page and is saying "printer not responding". The "color" and "black" orange LED lights are blinking.
I had recently (weeks ago) had problems with it saying the ink cartridges were empty, but found a way around that with a combination of button presses (forgot them now). It's been printing fine since that, several weeks ago (another flaw in this printer... premature out-of-ink notices).
So how to correct the all-black page printing? I swear... printers are stuck in the 1990s. The first company who truly makes a working printer that doesn't have these problems will have my eternal allegiance. This is not tolerable much longer. I learned Lexmark is worthless, and now it seems Canon is too.
What happens if you make a copy? What is on the label of the ink tanks that you are using?
