Explanation of Symbols The following symbols are used throughout this Service Manual.

Symbols Explanation Symbols Explanation

Check. Remove the claw.

Check visually. Insert the claw.

Check the noise. Use the bundled part.

Disconnect the connector. Push the part.

Connect the connector. Plug the power cable.

Remove the cable/wire from the cable guide or wire saddle.

Turn on the power.

The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specic functions and the

relationship between electrical and mechanical systems with reference to the timing of

operation.

In the diagrams, represents the path of mechanical drive; where a signal name

accompanies the symbol, the arrow indicates the direction of the electric signal.

The expression "turn on the power" means ipping on the power switch, closing the front

door, and closing the delivery unit door, which results in supplying 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, however, 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 eld. Therefore, the operations of the microprocessors used 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 the DC 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 communicated 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 be able to identify and isolate

faults in the machine.

Set the cable/wire to the cable guide or wire saddle.

Remove the screw.

Overview of the Electrical Circuitry

The nisher’s sequence of operation is controlled by the nisher controller PCB. The nisher

controller PCB is a 16-bit microprocessor (CPU), and is used for communication with the host

machine (serial) in addition to controlling the nisher’s sequence of operations.

The nisher 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 nisher’s various states (information on sensors and

switches) to the host machine through a serial communications circuit.

F-2-3

Overview of the Electrical Circuitry (Saddle Stitcher Unit)

The sequence of operations used for the saddle stitcher is controlled by the saddle stitcher

controller PCB. The saddle stitcher controller PCB has a microprocessor.

This microprocessor is used to control the sequence of operations and to handle serial

communications with the nisher controller PCB, driving solenoids and motors

in response to the various commands from the nisher controller PCB.

The saddle stitcher controller PCB is also used to communicate the state of various sensors

and switches to the nisher controller PCB in serial.

■Booklet Finisher

This product consists of the Finisher unit and the Saddle Stitcher unit.

The Finisher unit simply stacks sheets delivered from a host machine, offsets a stack job, or

staples and delivers the sheets to the trays according to commands delivered from a host

machine.

The Saddle Stitcher unit carries in, aligns, and stitches sheets delivered from the host

machine, and then feeds the resulting stack.

After these operations, it folds a stack of sheets and delivers it to the delivery trays of the

Saddle Stitcher unit.

There are four delivery methods.

The copy sent from the host machine is delivered to the ejection tray or processing tray

according to the ejection type.

Job offset or stapling is performed, according to the instruction from the host machine, for

copy delivered to the staple tray.

When ejecting from the processing tray, rear end assist guide is used in addition to the stack

ejection roller to eject the stack.

The inlet motor (M101), stack ejection motor (M102), and rear end assist motor (M39) are

step motors.

These motors are rotated forward or backward by the microcomputer (CPU) in the nisher

controller PCB.

The following two sensors are provided in the copy delivery path to detect the arrival or

passing of copies.

-Inlet sensor (PI103)

-Delivery path sensor (PI104)

Also, each ejection tray has sensors to detect the presence of copy on the tray.

-First tray paper sensor (PI111)

-Second tray paper sensor (PI112)

If the copy does not reaches or passes each sensor within prescribed time, the nisher

controller PCB determines that the jam has occurred and stops the operation.

Then it noties the host machine that a jam has occurred.

When all of the doors are closed after xing the jam, the nisher checks whether copy is

detected by any of the above two sensors (inlet sensor, delivery path sensor).

If any of the sensors detects a copy, the nisher determines that the jam is not xed and

sends jam processing signal to the host machine once more.

Paper Delivery Path

There are three ejection paths to tray 1 and 2 depending on the ejection processing.

Furthermore, Booklet Finisher has ejection paths for Saddle Stitcher Unit.

■Straight Ejection

When the equipment is set to non-sort, all copies are ejected through the following path.

■Processing Tray Path

This is the copy ejection path when the equipment is set to sort for paper size other than A4,

B5, or LTR or when set to staple sort.

Copies are delivered to the processing tray for aligning and stapling. Then they are ejected

using the rear end assist.

■Buffer/Processing Tray Path

This is the copy ejection path when the equipment is set to sort for A4, B5, or LTR paper size.

Feed two sheets of paper to buffer (two or three sheets if 2-point stapling).

Then they are aligned and stapled in the processing tray and ejected.

Even while stapling or offset is being performed, simultaneous stack ejection, which

simultaneously ejects copies delivered to the buffer and post processed stack in the

processing tray, is performed because copies are received continuously from the host

machine.

The stack delivered from the buffer is ejected to the processing tray and the stack processed

in the processing tray is ejected to the tray.

Simultaneous stack ejection operation is described below for two A4 copies between stacks

when the equipment is set to sort.

1) When the 1st paper reaches the switchback point, it is sent to the buffer unit and the rear

end of the paper is held by the buffer guide.

3) The rst delivery roller descends and works together with the stack delivery roller to deliver

the 1st and 2nd paper toward the processing tray.

At the same time,the stack in the processing tray is delivered toward the delivery tray by the

return roller and rear end assist guide.

4) When the stack in the processing tray is delivered to the delivery tray and the rear end of

the 1st and 2nd paper exits the 1st delivery roller, the 1st and 2nd paper are delivered toward

the processing tray by the stack delivery roller and return roller.

■Paper Delivery Path (Saddle Stitcher Unit)

A copy arriving in the nisher from the host machine is routed to the saddle stitcher by the

saddle stitcher apper.

The saddle stitcher executes stitching and saddling operations on the copy and then delivers

it to the saddle stitcher tray.

Stack Tray Unit

Tray Operation

This equipment has two delivery trays.

The upper tray is called tray 1 and the lower tray is called tray 2. The upper and lower tray

can move up and down independently.

The trays are moved up and down by the tray 1 shift motor (M107) and tray 2 shift

motor(M38).

Tray 1 paper sensor (PI111) and tray 2 paper sensor (PI112) are provided to detect the

presence of the paper stacked on the tray.

The home position of tray 1 is detected by the paper surface sensor (PI114) and the home

position of tray 2 is detected by the tray 2 paper surface sensor (PI115).

The home position is the top surface of the paper if papers are already stacked on the tray, or

the position where the edge of the tray is detected if no paper is stacked.

When the power is turned on, the nisher controller PCB drives the tray 1 shift motor (M107)

and tray 2 shift motor (M108) to return the tray to home position.

If the tray is already at home position, it is moved out of the home position once and then

returned to the home position once more.

If both tray 1 and tray 2 are at home position, this is performed for tray 1 and then for tray 2.

If the tray specied by the host machine is tray 2, the nisher controller PCB shifts the tray so

that

Tray 2 is at delivery port.

When paper is stacked on the tray, a prescribed number of pulses drive tray 1 shift motor

(M107) or tray 2 shift motor (M108) and the tray is lowered.

Then the tray returns to home position to prepare for the next stack.

The upper and lower limits of the tray are detected by three area sensors on tray 1 and tray 2

shift area sensor PCB.

The nisher controller PCB stops driving the tray 1 shift motor (M107) and tray 2 shift motor

(M108) when it detects the upper or lower limit of the tray.

Also, the ON/OFF combinations of the area sensors are used to detect over-stacking

according to the stack height for large size and mixed stacking.

The following gure shows the items detected with the ON/OFF combinations of the area

sensors.

The nisher controller PCB stops supplying +24V to the tray 1 shift motor (M37) and stops

the nisher operation when tray 1 switch (MSW103) turns ON.

Shutter Operation

When tray 1 passes the delivery section with paper already stacked, the stacked paper may

get caught by the delivery section.

A shutter is provided at the delivery section to prevent this.

The shutter closes when tray 1 passes the delivery section.

This is performed even when no paper is stacked.

When the shutter clutch (CL101) and stack ejection lower roller clutch (CL102) are ON, the

shutter moves up (close) when the stack ejection motor (M102) turns forward and moves

down (open, delivery enabled) when the motor turns backward.

The open/close of the shutter is detected by the shutter home position sensor (PI113).
