Question about Canon PIXMA MX850 Multifunction Printer
The power at my home went off then on again within a second. now i can't get my canon mx850 to turn on, it's on a surg protector. everything else is working fine. is there a reset button
I believe the fix is to disconnect power cord for an hour or so.
This is truly maddening... it's a bug in the design of their power supply. It's happened to me three times in the past few months.
The first time it happened, I haplessly stumbled onto the solution wisdos mentioned (unplugging it for a while) without realizing it. I thought it just started working for no apparent reason.
The second time I tried all sorts of tricks (not remembering the fact that I'd disconnected the power for a period), spoke with Canon support several times and finally had to agree to have them send me a replacement printer.
I'll skip the part about not being able to get the old printer's print head and inks out to put in the new one because it wouldn't budge without the power being on.
Now, with second printer and a five-second power failure, the same deal... won't turn on. This time I pulled the power cord from the printer and let it sit for a few hours. Plugged it back in and it came on.
The maddening thing is that Canon support didn't want to escalate this to someone who might understand the power supply and diagnose the problem properly... their solution was to send out a new printer. What a waste of time, money, and effort.

The same thing happened to my mx850. I tried everything but nothing worked. In frustration, I unplugged the printer. When I plugged it in the next morning and pushed the start button it came to life and is working fine. Maybe it just needed a rest? Hope this works for you.
