I have a kyocera km 3050 with blank copies , engineer before me fitted a reg clutch and after 20 copies ,started producing blank sheets.
When you stop copies at drum there is no image on drum surface.
swapped over dev unit ,drum unit and charge corona from another 3050 still no joy ,there are no error codes and the machine is feeding normally.
i have stripped down hvu assy and checked connections to main engine board.
wondered if anyone has had a engine board cause blank copies.
Thanks
