Canon imageClass MF642Cdw prints only full black pages

There is no error message on the screen. Printer takes unusually long doing its startup after wakeup, but then it accepts prints and only prints full black page.

I think this started after a power outage.

Greetings,

What happens if you print a test page?

You can also try resetting the printer, then re-test. If all you get is full black pages, it might have been damaged from the extreme power fluctuations. (surge, dip, etc.)
