My Canon Pixma Printer does not power on. Help anyone?

Does the scanner work? If the scanner works and the printer doesn't then it's definitely a print head problem. This is not a DIY fix. If the scanner doesn't work either then, you have a power supply problem. Usually this means that the small miniature power plug has been damaged (look at it to see if its bent or loose) or the mains power plug is broken inside. Change the mains power plug first as its easier... tools needed: a new mains plug, a small screwdriver (electrical contact type with lamp in handle works best), and a pair of wire insulation striping pliers. Just cut off the old plug and connect the wires to the two poles (this type of equipment is internally grounded (double insulated) so usually there is nothing connected to the ground terminal (leave it blank). Try the device and see if the scanner powers up. If it does, then you're home free. If it still doesn't power up, then you'll have to replace the miniature plug too. You need a 25 watt soldering iron and some fine (thin) electronics solder. Bear in mind that polarity (what is plus and what is minus or positive and negative) is important as there are only two fine wires and two terminals on the new miniature plug. Unscrew the jacket off the replacement plug and pass the wires through it first and then attach the two fine wires. Attach them by twisting gently through the small hole provided in each terminal and then check to see if the scanner works, if it does... disconnect and solder the wires in-place. When buying the new plug, take the old plug with you to buy the proper one there are many different types and a slight size difference can affect the connection. Worst comes to worst, the fusible link inside the power transformer (the plastic rectangular box the power cords plug into) is fried. In this case, you have to buy a new power cord... the whole thing. A fusible link is intended to protect the circuitry in the event of a mains power problem. It can't be replaced. Next time, plug your equipment into a surge protecting multi-tap (extension cord) specifically made for electronics. Belkin and ADP, among a few others, make reputable surge protectors.

the DPS-250AB is a 250W power supply, which is smaller than normal PS from most desktops. However, you should still be able to buy a spare at your local computer dealer. Don't pay more than ~50 USD for one.

Replacing a power supply is very easy. Simply open up your desktop. Your PS comes with standard cords mimicking that of your old PS. They will fit into *********** board (one big cord and maybe one smaller one), your hard-drive, your DVD-drive, your floppy-drive, etc.

The best solution is to take pictures with a smartphone of where the original cords are connected and simply copy that with the new power supply.

NOT ALL POWER SUPPLY CORDS HAVE TO BE CONNECTED SOMEWHERE! They simply come with redundant cords for future addons.

New power cord and software.

I believe you can buy a 15 volt tranformer from radio shack. You may have to buy the correct adaptor for it.

Power supply replacment

You should be able to replace the power supply. It is usually held in place by 4-6 screws. Unplug the cables on the motherboard and drives. Reconnect the new ones and away you go. A generic supply will be fine if it is of the correct physical size. Bring the old one with you when you go to get the new one.

Loss of power

I have a similar scanner, scanjet 5470c which is using the same power supply as 5400c and 5490c
2 weeks ago the scanner stopped working, yesterday i checked the scanner and found out that there was no power (12V)
the power module (black box) going into the 220V is a plastic box without service possibility. I took a screwdriver and a hammer to open the box. Inside the box i found a lot of electronics and yes a Fuse aswell. I did not have spare fuses, so like all bad boys i replaced the fuse with a wire, and guess what? .. yep I blew several main fuses in the house and now have a burned-out power supply.
the power module is still available at the HP Parts Store the part number is C8517-84201 i see a list price of 23 EUR

Before a buy a new power module I will first test the scanner with a spare 12VDC and see if he still works.

I will come back and tell you if it works...
