i have a canon mf8280cw that has very few pages on it. less then 400 total. i have had it a few years i think. the problem i am having is the print is not solid or dark. some times you can not even see black and white print. the problem is on both black and white and color. a lot of smoke and other air born particles have most likely gotten in to this printer. i would like to remove the toner cartridge holder and clean the laser glass to see if that helps. i have pulled the toner holder out but do not see a easy was to pull it out completely. thanks.
