TROUBLE SHOOTING DIAGONAL FEEDING AND DF
BELT DAMAGE BY CARRYING OUT CHANGES IN THE
PRESSURE RO LLER STAYS.

1.General: When making copies in the OC mode of thick original copies such as books, the

pressure roller stay of the conveyor area can become deformed and bent upwards
when too much pressure is placed on the conveyor area of the RADF. This can cause
diagonal feeding of original copies and in extreme cases the DF belt can be damaged.
