2.3.1 Stack Job Offset
0003-4552
Job offset operation offsets paper stack to the front or rear when ejecting to sort the paper stack.
The forward/backward movement of the copy delivered to the processing tray is controlled by the front aligning plate
and rear aligning plate.
The aligned copies are stapled or ejected according to the signal from the host machine.
When the power is turned on, the finisher controller PCB drives the aligning plate front motor (M33) and aligning
plate rear motor (M34) to return the two aligning plates to home position.
The name and function of motors and sensors used by the stack job offset function are shown below.
