Stack delivery roller angle control
To enhance the productivity, the paper is delivered to the delivery tray without passing the
process tray in case of lower delivery in non-staple mode.
In this case, since the angle when the paper is coming to the stack delivery roller is too steep
compared to the delivery from the process tray, the paper feed operation is not stable. Thus,
the stack feed upper roller moves to the downstream to enlarge the angle when the paper is
coming to the stack delivery roller to provide the stable paper feed.

When the delivery angle adjustment motor (M28) starts driving, the cam on the shaft rotates
and the swing guide is pushed, and then the stack delivery upper roller moves to the
downstream together with the swing guide.
Its home position is the position of the process tray lower delivery and is detected by the
delivery angle HP sensor (PS45).
