Why doesn't it turn on?

Check all wires and connections. If u confirm power reaching the innards of unit then there is an issue with the power supply of printer.

Printer won't turn on

Check your power supply cord or your power socket. If they are OK maybe there is electrical problem in your printer.
Good luck.

My Canon iP90 has been working perfectly but now won't work at all. Nothing. Not a bleep. The green light's on and I've done all the utility checks and they're fine. I've tried turning...

If you had done utility check and they are fine, had you try printing on a stand alone not using a computer. if you can print on a stand alone, there is no problem on the hardware side of the printer because u were able to print on a stand alone. you can focus now on the software side by uninstalling and re installing the driver of the printer and that should work.

Paper jammed and then MP810 lost all power. Cables and power supply good. Is there an internal fuse which could have blown? Thanks.

I'm certain there is a fuse, probably on the power supply board, to protect against the possibility of fire. Unfortunately, these are not normally user replaceable as they are often 'micro' fuses in a cylindrical case ~ 1/4" in diameter. Another type looks a lot like a low-power resistor with leads at either end. Both of these are soldered onto the board and normally aren't visibly blown but have to be checked with a meter for continuity.

Pixma 810: Suddenly the printer is dead. Despite power cable is connected with Pixma I can no longer turn the printer on. Is there a fuse anywhere? What is the solution? Best regards Peter Widmer


First of all please make sure that all the cables from/to the printer are connected properly. Now please use different power socket to make sure that the printer is getting power. If so then we can reset the printer. To reset the printer unplug it from/to the power socket and mains and let it sit without power for more then 10 minutes and then replace all the cables and print a test page. If still the issue is not resolved then you'll need to replace the printer cable. Hope this helps...please post back for further assistance.

I turned on the printer and it won' go. no lights dead.

Is this new? Was it working before in the same place with same pc?
Check power supply. Plugged in?, Local breaker at socket? Test meter the power plug that goes to printer. Still dead? Use as door stop. If new purchase, and still dead, take back for exchange or refund.

I have a Dell 1700 laser printer. During tornado, trees downed lined which landed in my yard. Anything with a power light on blew out. My computer just needed a new power supply, and it is fine now. I'm...

Well first it could be anything that blew on the device. First thing would be to check the power supply with a volt meter. Touch the barrel and the tip of the power supply and insure its sending the voltage that it specifies on the unit. If it isnt sending power the power supply blew. IF not it could be an internal problem. But let me know what happens from when you test the power supply with a volt meter and we will go from there. Thanks, Midwest-tek.

Error e803 checked power supply next to ac cord

Hi there,

Well most likely its a low voltage problem, check power outlet (110/220) or you need to replace the low voltage power supply board. Before replacing the power supply board you must check that the voltage is 24V by using a volt meter.
