(2) When the buffer roller lift solenoid (SOL2) is turned ON, the buffer rollers are lifted up, and then
the buffer tray guide motor (M2) opens the buffer tray.
The paper on the buffer tray is thus dropped onto the finishing tray.
At this stage, the patting solenoid (SOL3) is turned ON to drop the paper tapping arm so that the
paper will certainly be dropped onto the finishing tray.

(3) The paper dropped onto the finishing tray is then pulled into the finishing position by the paddles
driven by the paddle motor (M8) and the stack transport rollers-1 and -2 driven by the transport
motor (M7).
The finishing tray paper detection sensor (S12) detects whether paper is on the finishing tray or
not.
The home position of the paddles is detected by the paddle home position sensor (S3).
