2.6 Description of Interface Signals The 2 lines; TxD and RxD are used to transmit/receive signals between the equipment and the Finisher. When the Finisher is connected, the equipment detects the power supply signal (MFP-24V-ON) and confirms that the Finisher is connected to it with the status of the connection switch (SW4) and an MFPCONNECT-SEN signal from the connection sensor (S25).

3. DESCRIPTION OF OPERATIONS 3.1 3.1.1 Basic Operations GENERAL DESCRIPTION This machine receives paper transported from the connected device with its junction box, and then transports the paper to the stationary tray or the movable tray of the Finisher section or the saddle tray of the saddle stitch section.
• Center-binding mode Paper is exited following the procedure below when the Saddle Stitch Finisher is installed. 1 The stacker is moved to the stapling position according to the detected paper size. 2 Paper is transported to the stacker and then side alignment operation is performed. 3 The stack of paper is stapled after the alignment for the last page is finished. 4 The stacker is moved to the paper folding position to fold the paper.
3.1.2 Junction Box Paper transported from the connected device is then detected by the feeding sensor (S22) and caught with the feeding roller. Then it is transported to the Finisher section or the saddle stitch section after the transport path switching solenoid (SOL5) switches its transport path with a flapper. When it is transported to the Finisher section, the flapper does not move but the entrance roller transports it to the Finisher section.
3.1.3 Simple Stack Mode In this mode the transported paper is exited to the stationary tray or the movable tray directly, without any extra operation. During the exiting process to the movable tray, the shutter is lifted not to bring the paper into the finishing tray side and the movable tray is lifted up and down according to the stack height of paper. [A] Finisher paper feeding section Paper transported from the junction box is then caught with the entrance roller driven by the entrance motor (M1).
[B] Paper exit to the stationary tray Paper transported from the Finisher feeding section to the stationary tray side is exited to the stationary tray with the stationary tray roller driven by the exit motor (M11). The entrance sensor (S1) detects the paper transport to the stationary tray. The stationary tray paper-full sensor (S18) detects the overload of paper on the stationary tray. 3 Stationary tray paper-full sensor Stationary tray roller Entrance sensor Exit motor Fig.
[C] Paper exit to the movable tray Paper transported from the Finisher feeding section to the movable tray side is transported to the buffer tray with the exit roller driven by the exit motor (M11). Paper transport is detected by the transport sensor (S2). Transport sensor Buffer tray Exit roller Exit motor Fig. 3-7 The paper transported to the buffer tray it then exited to the movable tray by the buffer rollers driven by the buffer roller drive motor (M4).
[D] Operation of Movable Tray The movable tray is shifted up and down by the drive from the movable tray shift motor (M12) according to the paper exit from the buffer tray or finishing tray, and the amount of the paper stack. Rotation of the movable tray shift motor is detected by the movable tray shift motor sensor (S23). Whether paper is set on the movable tray or not is detected by the movable tray paper sensor (S17). Detecting the position of the movable tray is performed as follows. 3 1.
Movable tray paper exist sensor Movable tray shift motor sensor Movable tray paper-full sensor Movable tray shift motor Movable tray position-A sensor Movable tray position-B sensor Movable tray position-C sensor Fig.
3.1.4 Job offset stack mode / Staple stack mode The job offset stack mode exits stacks of paper by slightly shifting them to the front and rear alternately, and the staple stack mode staples and exits stacks of paper. In both modes, paper transported from the feeding section is stacked on the buffer tray in the unit of 1 to 3 sheets. The stacked paper is then moved to the finishing tray by the active drop mechanism.
[B] Mulch-active drop mechanism section The paper transported to the buffer tray is then moved to the finishing tray by the mulch-active drop mechanism to be aligned or stapled. (1) The paper on the buffer tray is pulled into the finishing tray side by the reverse rotation of the buffer roller drive motor (M4). In this step the paper pushing arm motor (M10) holds the trailing edge of the paper with the paper pushing plate.
(2) When the buffer roller lift solenoid (SOL2) is turned ON, the buffer rollers are lifted up, and then the buffer tray guide motor (M2) opens the buffer tray. The paper on the buffer tray is thus dropped onto the finishing tray. At this stage, the patting solenoid (SOL3) is turned ON to drop the paper tapping arm so that the paper will certainly be dropped onto the finishing tray.
[C] Bundle Job Offset Operation The bundle job offset operation is to sort bundles of paper by placing the first bundle a little forward and placing the next bundle a little backward, and repeating this set of movement. The paper transported to the finishing tray is bundled and each bundle is placed by the alignment plates driven by the front alignment motor (M5) and the rear alignment motor (M6).
[E] Paper exiting operation Bundles of the paper aligned or stapled on the finishing tray are then pulled up by the paper exit guide driven by the stack transport motor (M8) with the turning ON of the paper exit guide clutch (CLT2). Then the paper is exited by the paper exit belt driven by the stack transport motor (M8) and the stack transport rollers-1 and -2 driven by the transport motor (M2) onto the movable tray.
3.1.5 Operation in the saddle stitch section The center-binding mode binds a stack of paper at its center by stapling at two positions and then folds in half again to exit it to the saddle tray. In this mode paper transported from the feeding section is stacked on the stacker. The stacks of paper are aligned on the stacker and moved to the stapling position together with the stacker. Then the moved stacks are fixed and stapled, and then moved to the folding position.
[B] Stack transport A stacker carrier is moved to the stapling position or the folding position by the stacker motor (M14). The home position of the stacker is detected by the stacker home position sensor (S33). The presence of paper in the stacker is detected by the stacker paper detection sensor (S30). 3 Stacker paper detection sensor Stacker carrier Stacker motor Stacker home position sensor Fig.
[D] Paper holding The paper holding clutch (CLT4) is turned ON to let the saddle transport motor (M16) drive the paper holding cam. The home position of the paper holding cam is detected by the paper holding home position sensor (S38). saddle transport motor Paper holding damper Paper holding clutch Paper holding home position sensor Paper holding cam Fig. 3-20 [E] Stapling Stacks of paper aligned and fixed at the stapling position are stapled with two stapler units on the front and rear sides.
[F] Folding The folding blade is pressed onto the center of the stack of paper stapled and moved to the folding position, and then the folding roller lets the stack of paper sandwich the blade so that the stack will be folded again. The folding blade clutch (CLT3) is turned ON to press the folding blade to the stack of paper by rotating the blade cam driven by the folding motor (M17). The rotation of the folding motor (M17) is detected by the folding motor encoder sensor (S34).
After this, the stack of paper is folded as it passes the folding roller driven by the folding motor (M17). Folding motor encoder sensor Folding motor Folding blade clutch Exit transport sensor Folding roller Fig.
[G] Additional folding / exiting The stack of paper folded by the folding roller is stopped with the exit transport sensor (S41) at the stopping position. The folded paper is then folded again by moving the additional folding carrier roller forward and backward. The home position of the additional folding carrier is detected by the additional folding home position sensor (S39). The additional folding carrier is driven by the additional folding motor (M20).
