CAUTION: Stack Delivery Auxiliary Function
This machine is equipped with the stack delivery auxiliary mechanism as a means of
preventing misalignment of extra-length paper.
Misalignment occurs when the trail edge of paper hangs down on its own weight
at the stack delivery operation. The paper is then pulled back in the direction of the
arrow, causing its lead edge to move away from the stopper. The tray auxiliary plate is
pushed outside the machine before delivery occurs to hold the lead edge of paper. This
prevents misalignment. The tray auxiliary plate is pulled inside the machine at the end
of the delivery operation.

operation stopper. At this time, belt change lever shifts in the direction of the arrow to avoid
the contact with the paper.
Also the position of the operation stopper is adjusted to front/rear depending on the paper
size.
