My Konica 8031 show alert p-21 code. did a graduation adjustment, cleaned the Led's, inspected the belt but it still comes up. Another problem is that when I print a graphic image, I get a double or ghost like image on the sheet and color changes, eg. green bus card 10 up and green fades away to off yellow look, about 3" from edge on panel side.
Any help or suggestions would be greatly appreciated.
