35 CHAPTER FINISHER UNIT BASIC OPERATION. This chapter discusses the purpose and role of each of the finisher s functions, and the principles of operation used for the finisher mechanical and electrical systems. It also explains the timing at which these systems are operated.the symbol in drawings indicates transmission of mechanical drive, and signals marked by together with the signal name indicates the flow of electrical signals.. In descriptions of digital circuits on the finisher, indicates a high signal voltage level, while 0 indicates a low signal voltage level. Voltage values differ according to circuit. A microprocessor is used on the finisher. A description of microprocessor operation is omitted in this chapter as it is practically impossible to check internal operation of the microprocessor. Descriptions in this chapter also assume that PCBs will not be repaired at user sites. For this reason, descriptions of circuits on PCBs is limited to block diagrams. Two types of block diagrams are provided for separate functions: diagrams indicating details from sensors up to input sections of major PCBs, and diagrams indicating details from the output sections of major PCBs up the loads.

37 CHAPTER FINISHER UNIT BASIC OPERATION I. BASIC OPERATION A. Outline The finisher is designed to deliver copies arriving from its host machine, and its modes of delivery include simple stacking, job offset (Note), and staple. All operations involved in these modes are controlled by the finisher controller PCB, according to the appropriate commands from the host machine. In the case of the Saddle Finisher-F, copies from the host machine may be routed to the saddle stitcher unit. Swing guide drive system Alignment drive system Control system Stapler drive system Delivery drive system Feeder drive system Shutter drive system Tray drive system Saddle stitcher unit control system (Saddle Finisher-F) Figure -0 Note: The term job offset refers to shifting each sorting job, separating a single stack into several stacks.

38 CHAPTER FINISHER UNIT BASIC OPERATION B. Outline of Electrical Circuitry The finisher s sequence of operation is controlled by the finisher controller PCB. The finisher controller PCB is a -bit microprocessor (CPU), and is used for communication with the host machine (serial) in addition to controlling the finisher s sequence of operations. The finisher controller PCB responds to the various commands coming from the host machine through a serial communications line to drive solenoids, motors, and other loads. In addition, it communicates the finisher s various states (information on sensors and switches) to the host machine through a serial communications circuit. In the case of the Saddle Finisher-F, the finisher controller PCB not only communicates with the saddle stitcher controller PCB but also communicates the saddle stitcher unit s various states (information on sensors and switches) to the host machine. The ICs used on the finisher controller PCB are designed for the following: Q (CPU) Controls sequence of operations. Q (EP-ROM) Backs up adjustment values. Q7 Contains sequence programs. Q8/Q89 (RAM) Backs up initial setting data. Q (communications IC) Communicates with the host machine and the saddle stitcher unit. Q (regulator IC) Generates V.

50 CHAPTER FINISHER UNIT BASIC OPERATION. Saddle Stitch Delivery (Saddle Finisher-F) A copy arriving in the finisher from the host machine is routed to the saddle stitcher by the paper deflecting plate. The saddle stitcher executes stitching and saddling operations on the copy and then delivers it to the saddle stitcher tray. For discussions of stacks in the saddle stitcher, see Chapter.

54 CHAPTER FINISHER UNIT BASIC OPERATION C. Feeding and Delivering. Outline The finisher moves copies arriving from the host machine to the delivery tray, stapling tray, or the saddle stitcher unit (Saddle Finisher-F) according to the mode of delivery. On the stapling tray, the copies are subjected to job offset or stapling as instructed by the host machine. The first feed motor (M), second feed motor (M8) and inlet feed motor (M9) are stepping motors, and delivery motor (M) is a DC motor. These motors are controlled by the microprocessor (CPU) on the finisher controller PCB, and rotate either clockwise or counterclockwise. The paper paths are equipped with the following four sensors for detection of paper (arrival, passage): Inlet sensor (PI) Delivery sensor (PI) Stapling tray sensor (PI) Buffer path paper sensor (PI) In addition, each delivery tray is equipped with a sensor designed to detect the presence/absence of paper on it. No. tray paper sensor (PI) No. tray paper sensor (PI) If a copy fails to reach or move past each sensor within a specific period of time, the finisher controller PCB identifies the condition as a jam, and stops the ongoing operation, and at the same time, informs the host machine of the condition. When all doors are closed after the paper jam is removed, the buffer path inlet paper sensor (PI7) checks whether or not copies are being detected in addition to the above four sensors (inlet sensor, delivery sensor, stapling tray sensor and buffer path paper sensor). If the sensors detect a copy, the finisher unit judges that paper jams have not completely been removed, and sends the paper jam removal signal to the host machine again. -8 COPYRIGHT 000 CANON INC.

57 CHAPTER FINISHER UNIT BASIC OPERATION D. Job Offset. Outline In the job offset mode, sort jobs and entire copy groups are shifted to the front for delivery to the tray, and other copies are delivered to the tray without a shift. The copies are shifted by the alignment plate. The alignment plate is checked by the alignment home position sensor (PI) to find out whether it is at the home position. The finisher controller PCB drives the alignment plate motor (M) at power-on to return the alignment plate to its home position. The finisher controller PCB stops the delivery motor (M) when the trailing edge of the copy has moved past the feed roller. Then, the finisher controller PCB rotates the delivery motor counterclockwise, and drives the swing motor (M7). As a result, the drive of the delivery motor is transmitted to the swing guide to move up the guide. When the swing guide open detection sensor (PI8) detects the swing guide, the delivery motor stops, and the swing guide is held at the up position. When the swing guide has moved up, the feed belts attached to the feed roller move the copy to the stapling tray. The presence of paper on the stapling tray is monitored by the stapling tray paper sensor (PI). (The first sheet is fed to the stapling tray while the swing guide is moving up.) The finisher controller PCB drives the alignment motor (M) in advance, and keeps the alignment plate in wait at a point 0 mm behind the trailing edge of a sheet. Whenever one sheet is moved to the stapling tray, each sheet is aligned, and when the fifth or last sheet in a sort job/group is fed to the stapling tray, the guide plate retaining solenoid (SL) moves the guide plate away and under the stapling tray. From then on, the alignment motor shifts the sheets to the front by 0 mm. When the copy has been shifted, the finisher controller PCB rotates the alignment motor counterclockwise to move the alignment plate to a point 0 mm behind the trailing edge of the sheet. This alignment operation is repeated until alignment of the fifth or last sheet in a sort job is completed. At this time, the swing guide is moved down and is closed, and the delivery motor rotates clockwise to deliver the sheet. COPYRIGHT 000 CANON INC.

60 CHAPTER FINISHER UNIT BASIC OPERATION E. Staple Operation. Outline The stapler unit staples a stack of as many sheets as specified. The stapling position differs according to the selected staple mode and paper size. The stapler unit is checked by the stapler shift home position sensor (PI7) to find out whether it is at the home position. When starting operation after power-on, the finisher controller PCB drives the stapler shift motor (M) to return the stapler unit to the home position. If the stapler is already at the home position, it is kept as it is in wait. Stapler shift motor (M) Sheets Stapler Stapler shift home position sensor (PI7) Figure - - COPYRIGHT 000 CANON INC.

62 CHAPTER FINISHER UNIT BASIC OPERATION. First Sheet The finisher controller PCB stops the delivery motor (M) as soon as the trailing edge of the first sheet has moved past the feed roller. Then, it rotates the delivery motor clockwise to switch the gear drive to the swing motor (M7), causing the swing guide to move up. When the swing guide open sensor (PI8) finds the swing guide at the up position, the swing motor stops, maintaining the swing guide at the up position. When the swing guide has moved up, the feed belts of the feed roller move the sheet to the stapling tray. (The first sheet is fed to the stapling tray while the swing guide is moving up.) The presence of paper on the stapling tray is detected by the stapling tray paper sensor (PI). The finisher controller PCB drives the alignment motor (M) when the stapling tray paper sensor has detected paper to put sheets in order. The alignment plate is kept in wait in advance at a point 0 mm behind the trailing edge of the paper. The swing guide is kept in wait at the up position until the last sheet is output onto the stapling tray.
