Introduction

The following rules apply throughout this Service Manual:1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer-

ence to the timing of operation.In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates thedirection of the electric signal.The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results insupplying the machine with power.

2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, how-ever, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessorsused in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of theDC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be com-municated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and beable to identify and isolate faults in the machine."

2.1 Basic Construction

2.1.1 Functional Construction0023-7074

The puncher unit is optionally installed in the delivery path between the host machine and the finisher.When the paper delivered from the host machine reaches the puncher unit, it is fed by the punch feed roller. Then when the trailing edge of the paper is detected,the paper is tempo-rarily stopped and the punch axis rotates to punch holes in the trailing edge of the paper. These operations are controlled by the finisher controllerPCB and the punch controller PCB drives each puncher component.

F-2-1

2.2 Feed Drive System

2.2.1 Overview0023-7075

The puncher unit is located on the feed path between the host machine and the finisher, and successively punches holes when the paper stops temporarily.The paper delivered from the host machine is fed by the punch feed roller. The punch feed roller is driven by the punch feed motor. When the trailing edge of thepaper reaches the puncher unit, the inlet roller of the finisher unit temporarily stops the paper and holes are punched on the trailing edge of the paper.The following shows the names and functions of the motors and sensors used in punching operation:

T-2-1

T-2-2

2.2.2 Constraction of the Control System0023-7076

The puncher unit consists of a die and hole puncher (punch blade).The hole puncher is driven by the punch motor (M61). The hole puncher is attached to theeccentric cam of the punch shaft, and rotary action of the punch shaft is converted to reciprocal motion to perform punching.Punch motor (M61) is a DC motor. The home position of the punch shaft is detected by punch home position sensor (PI63). To stop the DC punch motor accuratelyat its home po-sition, the punch motor clock sensor (PI62) counts a predetermined number of clock pulses to stop the punch motor. A single punch operation isperformed by rotating the punch shaft 180° from its home position.Five light sensors (photosensor PCB) are located at the upper side of the inlet paper feed path of the puncher unit and a set of five LEDs (LED PCB) are located atthe lower side. These sensors and LEDs function as five sensors. The frontmost sensor (LED5, PTR5) are the trailing edge sensor and are used for detecting thetrailing edge of the paper. The remaining sensors (LED1 to LED4, PTR1 to PTR4) are horizontal registration sensors, and are used for detecting the inner position

of the paper for determining the hole punching position.The punch motor, puncher unit and above sensors comprise the punch slide unit. This unit moves backwards and forwards according to the size of the paper. Back-ward and forward movement is driven by the horizontal registration motor (M62). The home position of the punch slide unit is detected by the horizontal registrationhome position sensor (PI61). The horizontal registration motor (M62) is a 2-phase stepping motor.The punch motor and horizontal registration motor is driven by the punch controller PCBaccording to control signals from the finisher controller PCB.Punch scraps caused by punching are stored in the punched scrap container. Scrap full detection is performed by a reflective sensor (LED6 and PTR6 on the scrapfull detector PCB unit).

F-2-2

2.2.3 Punch Operation0023-7077

The hole puncher is driven by the punch motor (M61), and its position is monitored by the punch home position sensor (PI63).The hole puncher makes a single round-trip movement (punching) as the punch shaft rotates 180°Å@from home position.In the case of a 2-or-3 hole type, the half sector of the punch shaft is used when punching 2 holes while the half sector on the opposite side is used when punching3 holes as instructed by the host machine.

<2-/4-hole Type>At the home position, the punch home position sensor is ON. Punching of the first sheet ends when the punch shaft has rotated in the forward direction 180°, andthe state of the punch home position sensor has changed from OFF to ON. Punching of the second sheet ends when the punch shaft has rotated in the reverse direction180° , and the state of the punch home position sensor has changed from OFF to ON.The following illustrates punching when two sheets are punched.

1) A hole is punched in the trailing edge of the first sheet.

<2-/3-hole Dual Use Type>At the home position, the punch home position sensor is ON. To punch two holes, punching of the first sheet ends when the punch shaft half peripheral area hasrotated in the forward direction 180°, and the state of the punch home position sensor has changed from OFF to ON. At this time, the 3-hole puncher is movedreciprocally in the escape direction (hole puncher rise direction) on the remaining half peripheral area on the punch shaft. Punching of the second sheet ends whenthe punch shaft half peripheral area has rotated in the reverse direction 180°, and the state of the punch home position sensor has changed from OFF to ON. Alsoat this time, the 3-hole puncher is moved reciprocally in the escape direction (hole puncher rise direction) on the remaining half peripheral area on the punch shaft.To punch three holes, the 2-hole puncher is moved reciprocally in the escape direction (hole puncher rise direction).The following illustrates punching when two sheets are punched with two holes.

2.2.4 Horizontal Registration Operation0023-7078

Horizontal registration drive of the punch slide unit is performed by the horizontal registration motor (M62). The home position of the punch slide unit is detectedby the horizontal registration home position sensor (PI61). The punch slide unit detects the trailing edge of the paper by the trailing edge sensor (LED5, PTR5) andhorizontal registration sensors (LED1 to 4, SREG1 to 4) and is moved to the trailing edge position matched to the paper size.The following shows horizontal registration operation.

1) When the leading edge of the paper from the host machine is detected by the trailing edge sensor (LED5, PTR5) on the puncher unit, the horizontal registrationmotor (M62) starts to move the punch slide unit towards the front.

2) After the horizontal registration sensors (LED1 to 4, PTR1 to 4) detect the edge of the paper at its inner side in keeping with the paper size signals arriving fromthe host ma-chine, the horizontal registration motor (M62) drives the punch slide unit to a predetermined position further towards the front, and stops the unit atthis position.

F-2-10

3) When the trailing edge sensor (LED5, PTR5) detects the trailing edge of the paper, drive of the punch feed motor (M63) is stopped to stop paper feed. Next, thepunch motor (M161) is driven to punch holes in the paper.

F-2-11

4) When punching ends, drive of the punch feed motor (M63) is started, the horizontal registration motor (M62) is operated in the reverse direction, and the punchslide unit is returned to its home position where it comes to a stop.

5) Even if paper to be punched continues to arrive, the punch slide unit returns to its home position for each arriving sheet, and steps 1 to 4 are repeated.
