(Up to 5 sheets are stacked and exited. 5VDC PS709 SGND PS709 5VDC PS710 SGND PS710 MAIN BODY FS CB During sorting and stapling, paper exited by the conveyance section is sent to the alignment section by the M702 (paper exit motor) reverse direction, then aligned by the alignment plates driven by the M703 (alignment motor, (rear)) and the M704 (alignment motor, (front)). The home position of the alignment plates is detected by the PS709 (alignment plate detect PS (rear)) and the PS710 (alignment plate detect PS (front)). The FS CB (FS control board) controls the M702, M703 and M704. The related signal are passed to the PS702 (paper entrance detect PS). c. Staple mode operation In the staple mode, the M703 and M704 are released after the stapling action is completed. The ON/OFF timing of the M703 and M704 is set as the M702 is turned from OFF to ON, and the PS702 is turned OFF after the specified period of time. 17 FS-107 2.

A mechanical clutch is connected to M702 (paper exit motor). A mechanical clutch can convey the forward direction driving power to the exit roller with certain movement. The M702 is responsible for speed control for connection with the mechanical clutch, for sending the alignment section at the reversal rotation, and also during the usual paper exit. The M702 is controlled by the FS CB (FS control board). ­ (2) M703 OUT A, M703 OUT A, M703 OUT B, ­ M703 OUT B (FS CB -> M703) Drive control signal for M703 24V 0V ­ (3) M704 OUT A, M704 OUT A, M704 OUT B, ­ M704 OUT B (FS CB -> M704) Drive control signal for M704 24V 0V The related signals are M707 (paper pressure motor), M708 (stapler motor), PS701 (paper pressure PS), PS702 (paper entrance detect PS), PS703 (paper exit detect PS), and PS707 (no paper detect PS). 18 FS-107 1. Operation During paper exit, both upper and lower exit rollers are compressed as a consequence of the operation performed by M707, and that condition is detected by the ON/OFF state of PS701. Paper Stack Control a. Non-staple mode operation The ON/OFF timing of M702 is such that it turns ON during the OFF of PS3, and turns OFF during the OFF of PS702. After the paper exit tray goes up until PS703 turns ON, M706 moves the tray up and down in order to keep the ON state of PS703 during paper exit. 24VDC 24VDC 24VDC 5VDC 5VDC SGND SGND PGND PGND PGND M706 DRIVE 1 M706 DRIVE 2 M706 5VDC PS702 SGND 5VDC PS703 SGND 5VDC PS704 SGND 5VDC PS706 SGND 5VDC PS716 SGND PS702 PS703 b.

During the automatic switching mode of the tray, a message is not put up on the LCD. The tray located 1 step below is brought to the paper exit position by a vertical movement of M706 (tray up/down motor). The M706 is controlled by FS CB (FS control board). The related signals are PS702 (paper entrance detect PS), PS703 (paper exit detect PS), PS704 (tray full-stack detect PS), PS706 (tray lower limit detect PS), and PS716 (tray count PS). The automatic switching mode of the tray can be controlled using the 25 modes of the main unit. 2. a.

Operation Up/down operation When the tip of the paper turns PS702 ON, the tray is driven down by a certain amount. After the rear of the paper turns PS702 OFF, M706 turns ON driving the tray up until PS703 is turned ON. 24VDC 24VDC 24VDC 5VDC 5VDC SGND SGND PGND PGND PGND 24VDC 24VDC M705 OUT A M705 OUT A M705 OUT B M705 OUT B Stapler Control M705 b.
