Stack trailing-edge assist operation
To improve stacking performance when ejecting jobs delivered to the processing output bin, a stack
trailing-edge assist guide supports the back of the stack during stack ejection.

Stack job offset
The job-offset operation offsets the paper stack to the front or rear when ejecting to sort the paper
stack. The forward/backward movement of the sheet delivered to the processing output bin is
controlled by the front-aligning plate and rear-aligning plate. The aligned copies are stapled or ejected
according to the signal from the product. When the power is turned on, the stacker controller PCA
drives the aligning-plate front motor (M103) and aligning-plate rear motor (M104) 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.
