Strangely enough 2 years after mine spontaneously stopped working it spontaneously started working again. There is no reasonable explanation for it. Once I was able to turn it on most of the catridges were dry. It may be a built in “punishment” Canon has put in their printers to deter you from holding the paper feed button enough times to default to printing in only black and white. Nonetheless I am over Canon products. Will never buy another again. Completely fed up. The ink cartridges are so insanely expensive and I perhaps get only 10 photos out of them. It may be more economical to return to a fuji film developed film camera than these ridiculous digital camera photos which can only be shared on computers. I’m sorry to say there was no solution to this and I am quite tech savvy. I’ve soldered power jacks on mother boards, upgraded processors in laptops and replaced screens in laptops. I can completely dismantle a laptop and have every screw and part diagrammed, clean it (dust etc), reapply heatsink to...
I suspect they engineered these to fail after so many years. I wouldn't often use the printer but when I used it I needed it. The ink would mysteriously disappear even when I wasn't using it and I had to buy ink cartridges for it often. So that is what I was doing. I turned the printer on, opened the ink door and checked the number on the cartridges. Closed the door then went into the other room to buy the ink. When I returned to the machine the power was off and I could not turn it back on. Changing outlets, reinserting the power cord, and holding down the power button to no avail. It was meant to fail. I will never buy another printer or product for that matter from Canon.
