Laser printer drum damaged by extended exposure to light?
(From: DenFrodo (denfrodo@aol.com).) Yes, with extended exposure. I remanufacture toner cartridges for a time. Long term exposure to light will effect the photoconductive layer. We even cover areas of some (scratched) after-market drums and exposed them to sunlight to see how it effected them. It takes extended exposure to show an effect. No, the printer will not detect the problem and the printer will probably print dark for the basic ‘positive’ image (a dark area is exposed to light) laser printer. A scanner or copier might print light (reflective light of the ‘white’ surface exposes the surface of the drum. Good Luck. Repeating images on laser printer This likely means a faint ghost of the main printout at a distance equal to the circumference of one of the rollers or photosensitive drum. Depending on where the problem originates, this could be a bad wiper (cleaning) blade, faulty corona, or incomplete fusing. • If the distance between successive images is equal to the circumference
