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.
