[. . . ] Within one rotation of the gear, the paper is pushed out (forwarding motion) and returned to the standby position (return motion). When PS813 goes ON, the exit levers have returned to the standby position and M805 is turned OFF. Stapling mode operation In stapling mode, when the stapler motor (M802 or M803) that has last finished to operate goes OFF, M805 goes ON for the specified time and drives the exit levers. Other operations are the same as for nonstapling mode. b. 16 FS-109 Paper Stacking Control b. 24V 24V M810 DRV A M810 DRV A M810 DRV B M810 DRV B M810 24V 24V M811 DRV A M811 DRV A M811 DRV B M811 DRV B SGND SGND 5V 5V PGND PGND PGND 24V 24V 24V M TxD M REQ S ACK M RxD M ACK S REQ M811 Tray auto-switching control When copying is carried out with tray 2 or tray 3 specified as output tray and the specified tray becomes full, causing PS807 or PS809 to become ON, the output tray is automatically switched to the other tray. This operation is also valid if tray 1 is specified as the output tray. The output tray will be switched to tray 2 or tray 3. Switching from tray 2 or tray 3 to tray 1 is not possible. 2.

The drive force of motor M810 (tray 2) or M811 (tray 3) is used to operate the rollers and stack the paper on the tray. M810 and M811 operation is controlled by the FNSCB (FNS control board). 24V 0V (2) M811 DRV A, A, B, B (FNSCB to M811) M811 ON/OFF drive signal 1. a. Operation Paper stacking control When M805 (paper exit) goes ON, M810 (tray 2) or M811 (tray 3) are set to ON after the specified time. When M805 goes OFF, M810 or M811 are set to OFF after the specified time. While the motor is ON, the rollers of the tray are driven and the paper that was placed on the rollers is stacked. The stacking section of the tray is pushed up by a spring. When the maximum allowable number of sheets has been stacked, the stacking section contacts the bottom of the tray and PS807 (tray 2 full-stack detect) or PS809 (tray 3 full-stack detect) goes ON. When PS807 or PS809 are ON, no copy operation will be carried out when the respective tray is selected. 24V 0V 17 FS-109 Stapler Movement (M806) Control Stapler Control 24V 24V M806 DRV A M806 DRV A M806 DRV B M806 DRV B M806 SGND SGND 5V 5V PGND PGND PGND 24V 24V 24V M TxD M REQ S ACK M RxD M802 DRV 1 M802 DRV 2 VCC PS820IN PS821IN PS822IN GND M802 PS814 VCC PS814IN GND M803 DRV 1 M803 DRV 2 VCC PS817IN PS818IN PS819IN GND M803 24V MS804 24VIN SGND SGND 5V 5V PGND PGND PGND 24V 24V 24V M TxD M REQ S ACK M RxD M ACK S REQ 24VOUT M ACK S REQ MS804 24VIN MAIN BODY FNSCB SD802 24V SD802 DRV The position of the stapler units at the front and rear with respect to the paper is adjusted using the driving force of the M806(stapler movement). Operation of M806 is controlled by the FNSCB (FNS control board). 1. Operation Normally, the stapler units are stationary, positioned so that the stapling is carried out parallel to the paper edge. This position is detected by PS814 (stapler unit HP). When the stapling position is changed according to a command from the main body, M806 goes ON and the two stapler units at the front and rear are moved simultaneously. The M806 OFF timing is controlled using the number of drive step from when PS814 went OFF. MAIN BODY FNSCB Stapling is carried out by driving M802 (stapler (rear)) and M803 (stapler (front)). Operation of M802 and M803 is controlled by the FNSCB (FNS control board). [. . . ] 7 17 21 11 1 19 3 15 Model FS-109 1st Edition Konica Business Technologies, Inc.
