Answer to "Why won't my printer turn on?"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.

Answer to "Why won't my printer turn on?"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.
