8. MAIN TRAY SECTION
8.3.2 Main tray up/down control
The driving force of the tray up down motor (M3) rotates the lift pulley by the belt and the gear to wind up the lift
wire. The main tray goes up or down according to the direction in which the up/down wire is wound up. When
the lift pulley /Lw rotates clockwise as seen from the front, the main tray goes up and when it rotates counter-
clockwise, the tray goes down.
A. Non-staple up/down control
According to the FS operation signal from the main body, the tray up down motor (M3) raises the tray until the
tray upper limit sensor (PS2) turns ON.
When paper passes through the main tray paper exit sensor (PS10), M3 lets down the tray. M3 raises up the tray
again a specified period of time after PS2 turns OFF and stops it when PS2 turns ON. The above steps are
repeated for each sheet of paper.

B. Staple control
When the stacker empty sensor (PS20) detects the trailing edge of paper, the main tray is brought down by the
tray up down motor (M3). And M3 reverses the rotation after a specified period of time to bright up the tray. It
stops when the stapler paper exit upper limit sensor (PS7) turns ON.
