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.
