My Canon started to do the same thing. All that the screen on the printers display will show is the Canon logo. I can't figure how to factory reset the printer


I have the same issue. My printer is a MX492. Cannon maybe pushed some kind of update. Now I'm headed to the store for a new printer. 

Well, I have never liked Canon products, but not ready to spring for a new printer. Waiting for Canon to fix it. How many businesses are affected?

My business is affected. 


I am having this issue too!  Happened out of nowhere!  Did they force an update that screwed it up?  Looks like everyone's issue just came up at the same time! 


Mine was doing same thing after storm last nite. After searching online I did the following: unplugged printer from power strip, disconnected printer at my modem/wifi router box, pushed power button on printer 10x (according to Canon), plugged printer back in, reconnected printer to modem/router.  Now it's working.  I think the important things were disconnecting power & internet.  Hope something from this helps you.


Oh no.  I spoke too soon.  It worked long enuf to print one document and now back to power cycling.

See my update. Your fix works if you leave the printer on. At least it has so far. Have printed several things and functions seem to be there.

Try this article. The printers will ONLY print from a USB for now until Cannon fixes what they clearly caused...
