A crack sound looks like it comes from gears on machine that transmits motion to fuser unit. At the begginning no sound then asmore copies made it becomes louder and it does'tstop. When continue copying some times it stops. I swapted fuser unit but the same i greased gears with no results. Gears looks ok. Any idea?
Also at screen a key appears on paper cassete icons and it blocks user to change paper size. How can i clean the key.?
