I have issues with a few mpc2500 machines dog earing left hand front corner of a4 page, this is after replacing the fusing unit, bridging unit, and sr790 (not that sr790 is causing it), but due to dog earring the entrance to finisher catching dog ear and causing jam.
fusing unit was whole unit, brand new, can dog ear from all trays, not every copy approx 1 in 20 pages dog earring and folding back, is after the fusing hot roller and pressure roller as dog earing is not folded back and pressed, curled dog earring.
installed tray heaters for moisture in paper trays, increased fuser idle. clean and inspected gates and paper guides.
anymore advice would be helpful.
we have about 5 of these doing so not one machine issue.
