STACKER Q5686A/Q5687A 3.2.5 Stacker paper exit control The control of the paper exit belt of the stacker is made by the paper exit roller motor (M707) through the coupling gear by controlling the finisher control board (Finisher CB). A. Paper exit operation The paper exit to the main tray in the staple mode and the paper conveyance to the folding section in the three-folding mode are made by the paper exit arm [2] installed to the paper exit belt [1]. The paper exit belt [1] is driven by the paper exit roller motor (M707) with the coupling pin [3] connected. II UNIT EXPLANATION The home position of the paper exit arm is detected by the paper exit belt sensor (PS709).
M707 [3] [2] PS709 [1] B. Paper exit arm control (1) Staple mode (When the vertical length is shorter than B5R) When the stapling operation is completed, the paper exit roller motor (M707) rotates to drive the paper exit belt of the stacker section. This causes the paper exit arm to hook the paper to raise it up to the paper exit roller. And then, the paper exit roller discharges the paper to the main tray. When the paper exit belt HP sensor (PS709) detects the change from off to on, M707 stops. (2) Staple mode (Other than the above) When the paper size is other than the above, the paper exit opening is open. When the stapling is completed, the paper exit opening motor (M708) operates.
When the paper exit open- ing HP sensor (PS712) detects a fact that the paper exit opening is fully closed, the paper exit roller motor (M707) rotates to drive the paper exit arm of the stacker section. This causes the paper exit arm to hook main tray. the paper to raise it up to the paper exit roller. And then the paper exit roller discharges the paper to the When the paper exit belt HP sensor (PS709) detects the change from off to on, M707 stops. 2-26
