[. . . ] M721 (sub-tray paper exit) Control M721 (sub-tray paper exit) starts its high-speed rotation when PS701 (sub-tray paper exit) detects the leading edge of the paper. When PS704 (FNS entrance) has detected the trailing edge of the paper and a predefined time period has elapsed since then, the rotation of M721 changes to low. When PS701 detects the trailing edge of the paper and a predefined time period has elapsed, M721 stops. Sub-tray full detection When the papers ejected to sub-tray reach to specified height, PS719 (sub-tray full) turns ON, and FNS transmits "sub-tray full" information to the main body. When the main body receives it, the message is displayed on the operation panel. b. 2-13 2 UNIT EXPLANATION M721 FS-110/FS-210 MAIN TRAY SECTION [1] Composition 2 Main tray Stapler paper exit upper limit PS (PS707) Tray upper limit PS (PS702) 2 UNIT EXPLANATION Counter reset PS (PS715) Upper up/down pulley Tray lower limit PS (PS703) Tray up/down motor (M703) Timing belt Up/down pulley/L Old type New type Tray up/down motor (M703) fs2102001 [2] Mechanism Mechanism Main tray up/down*1 Paper detection*2 Method Wire drive Photo sensor *1 Main Tray Up/Down The tray up/down motor (M703) and the worm gear installed on the motor shaft perform the winding operation of the up/down wire. The rotation direction of the motor shaft determines the moving direction of the main tray, i. e. If the up/down pulley/L rotates clockwise seen from the front, the main tray rises. 2 In old type, a brush motor is used for M703 but in new type brushless motor and timing belt are used to enhance the silence effectiveness. *2 Paper Detection The distance between the top surface of the piled sheets on the main tray (the top surface of the main tray if there's no sheet on the tray) and the paper exit opening is monitored using the tray upper limit PS (PS702) and the stapler paper exit MODEL 7155/7165/7255/7272 upper limit PS (PS707). This distance is kept constant to avoid misalignment of delivered sheets. The counting program, built in the FNS, counts the number of delivered sheets on the main tray during continuous copying. When the total number of delivered sheets reaches a maximum (values are predefined depending on type/size of paper), the copying operation is suspended. However, when some delivered sheets are removed, the main tray is raised and the counter reset PS is activated. The tray lower limit PS (PS703) detects the bottom of the main tray. The number of delivered sheets on the main tray is not counted by the software counter during non-continuous copying. PS703 is used for the limitation of the number.

When PS706 (main tray paper exit) detects the paper, M703 lowers the tray. [. . . ] 3 DIS. /ASSEMBLY (3) Remove the two screws securing the rail stopper. CAUTION: Place something under the drawn stacker unit to prevent the FNS from falling due to the weight of the unit.

Caution: Do not use hands to move stapler units to horizontal direction. (Otherwise the belt and the gear teeth skipping may occur. ) Caution: Be sure to perform the adjustment work described in the "FNS Stapler Upper/ Lower Positions Adjustment" of the manual, "Adjustment, " after you have attached the clincher.
