Hi I'm new here and hope I did this right.I have a customer that has an HP-8000. From tray 1 it seems to not fuse correctly.It may not fuse from other trays but they complain about tray 1. The printer gets no errors but the toner comes off. We have changed the fuser twice and the DC controller. Nothing seems to help. Hp now suggests changing the wiring harness the fuser plugs into,but its a project and am looking for any other suggestions.
