I had the same thing happen with my Canon PC940 copier. One day, copies were great, the next time I used it, they looked like the toner had run out. I live in an area of high humidity so I suspected that the toner may have clumped together. I put the cartridge in the oven at 150-175 degrees for two hours and, voila, everything began working again.
