I have a Konica 7821 DXN office printer. Prints fine in black. Color is very light or blurry. I have replaced the toners and still no difference. Any suggestions? These toners were very expensive and I still cant print in color. Any help would be greatly appreciated.

Did you clean the led heads?

When you replaced the toners, did you put new toners in or rebuild the toner cartridges? I have found that when the toner cartridges are rebuilt, they clog the drum unit recycling path and cause light prints and sometimes gear jumping noises.
