We are working on a WC 4260 but same issues could be similar on a 4150 or 4250.
I have replaced the drum and the toner but still getting a grey print instead of black. It appears that the drum is not attracting enough toner since a half print test shows more of a grey print on the drum. I have cleaned the LSU window so am assuming that the issue has to do with the high voltage, but I would like to be able to test for that instead of just following the service manual and replacing the HVPS.
I would really appreciate anyone comments or help. Thank you.
