Hi Kilowatt,
Thank you for using the Support Forum. Please take a look at this solution for light and faded prints from the support page for your machine and see if it helps. If not please consider contacting your support centre for further assistance.
My printouts from the 4595 are coming out too light. This is from network print, photocopy and builtin report. I have put in new toner and a new drum cartridge, also tried cleaning the laser window, no difference. Any ideas what could be causing this?
