Question about Canon PIXMA MP780 All-In-One InkJet Printer
It stopped working suddenly. It does not respond to the On button. I removed and checked the cord and found that the cord was getting power.
Sometimes when the printhead goes bad, it keeps the printer from turning on. Try removing the inks and printhead and turn on. If it comes on, replace the printhead with a new one and don't put the bad one back in. The printhead is QY6-0049-000 about $50.00
