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 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 flipping 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 field. 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."

2.2 Basic Operation
2.2.1 Overview
The side paper deck (hereafter, "deck") is capable of accommodating as many as 3500 sheets of paper at a time (A4/
LTR/B5; 80 g/m2), ready to pick up and feed paper in response to control signals from its host machine' s DC
controller.
The lifter of the deck is driven by the deck lifter motor (M102), and the pickup operation is executed using the drive
from the deck main motor (M101).
2.2.2 Pickup Operation
The paper placed in the deck is held up by the lifter at a specific point of paper pickup.
When the Start key is pressed and the deck pickup clutch (CL102) goes on, the pickup roller starts to rotate by the
drive of the deck main motor (M101), thus picking up paper. At this time, the pickup/feed roller ad the separation
roller make sure that no more that a single sheet of paper is moved ahead. Thereafter, when the deck pickup sensor
(PS101) detects the paper, the deck pickup roller release solenoid (SL101) goes on so that the pickup roller leaves
the surface of the stack of paper.
0003-2610
0003-2616
2-4
Page 17
Chapter 2
The deck feed roller starts to rotate when the deck feed clutch (CL101) goes on. The paper is then moved to the host
machine' s registration roller, where it is arched to remove any skew.
The registration roller serves to control the paper so that its leading edge will match the image on the photosensitive drum.

2.2.3 Controlling the Deck Main Motor (M1D)
0003-2623
1. Controlling the Deck Main Motor (M101)
The deck main motor is controlled by the host machine' s DC controller. The following diagram shows the circuit
used to drive the deck main motor, and the circuit has the following functions:
1 turns on/off the deck main motor
2 changes the speed of rotation of the deck main motor
a. Turning On/Off the Motor
When the deck main motor drive signal (DMON) from the host machine goes '1', the motor drive circuit goes on so
that the motor starts to rotate at a specific speed. When the deck main motor drive signal (DMON) goes '0' , on the
other hand, the motor drive circuit goes off to stop the motor.
The host machine' s DC controller monitors the rotation of the deck main motor with reference to the deck main
motor PULL lock signal (DMPLK); if the PULL lock signal remains '1' for 900 msec or more white DMON is '1', it
will indicate 'E043' on the host machine' s control panel.

b. Changing the Speed of Rotation of the Motor
The deck is designed to automatically change the speed of pickup so as to support future host machines. The pickup
speed is changed in response to external clock signals (MOTOR CLK) that are sent by the host machine' s DC
controller to the side deck drive PCB in keeping with the speed of motor rotation. The relationship between the speed
of motor rotation and the frequency of the external clock signals is as follows:
T-2-1
Drive speed Rotation of motor shaft External clock setting (Hz) Drive mode
Speed 12885.93 1443used when picking up plain paper
Speed 22308.80 1155used when picking up H/H color (PS)
Speed 31847.05 924used when picking up heavy paper (1/3 PS)
MEMO
When making color copies/prints, the drive speed is shifted to speed 2 or 3.

2.2.4 Controlling the Deck Lifter Motor (M2D)
2. Controlling the Deck Lifter Motor (M102)
The deck lifter motor control circuit is found as part of the side deck driver PCB. The following is a block diagram
of the circuit:
The combination circuit shown in the diagram consists of various logic circuits, and the deck lifter motor is rotated
in normal or reverse direction using combinations of the deck lifter drive signal (DLMON*) and the deck lifer ascent
signal (DLUP*) from the host machine' s DC controller and the output signals of various sensors.
If, for some reason, the deck lifter position sensor (PS104) does not detect the lifter within 60 sec after the deck lifter
ascent signal is generated, an error code (E041) will be indicated on the host machine' s control panel.
1 Conditions Used to Move Up the Lifter
the deck is joined with its host machine, i.e., the deck set signal (DSET) is '1'.
the deck (compartment) is closed, i.e., the deck open detection signal (DOPND*) is '1'.
the deck (compartment) is closed, i.e., the deck open detecting switch is 'on'.
the deck lifter upper limit signal (DLUL) is '0' and, in addition, the deck lifter position detecting signal (DLPD) is '0'.
the deck lifer motor drive signal (DLMON*) is '0'.
the deck lifter ascent signal (DLUP* is '0'.
In the presence of these conditions, the lifter starts to move up.

2. Changing the Deck Paper Size
To change the paper size of the deck, you must move the guide plate in the deck to suit the user' s needs and then
select the correct paper size in service mode: OPTION>ACC>DKP.
2.3.3 Detecting the Level of Paper
3. Detecting the Level of Paper in the Deck
The deck uses the deck paper supply position sensor (PS107), deck paper level sensor (PS108), and deck paper
sensor (PS102) to check the level of paper inside its compartment; the result of the check is indicated on the host
machine' s control panel. The following table shows how a check is made with reference to the states of the sensors:

2.4 Deck Lifter
Chapter 2
2.4.1 Detecting the Presence/Absence of Paper
The lifter of the deck is joined to a reel by means of a cable, and is driven by the deck lifter motor (M102); i.e., the
lifter moves up or down depending on the direction of rotation of the motor.
When the deck (compartment) is pushed inside the host machine, the deck open detecting switch (SW101) is pushed.
The lifter starts to move up as soon as the deck open sensor (PS109) detects the lightblocking plate; the lifter stops
to move up when the deck position sensor (PS104) detects the top of the stack of paper placed on the lifter
In the rare event that the lifter should fail to stop moving up after the sensor lever blocks the deck lifter position sensor
for some reason, the deck lifter upper limit sensor (PS103) will go on to stop the lifter, thereby preventing damage
to the deck.
The lifter, on the other hand, starts to move down when the deck open switch (SCREW100) is pushed, and will keep
moving down until the lifter moves past the sensor lever of the deck paper supply position sensor (PS107), i.e., falling
edge of the sensor output.
The addition of paper in this condition will push the lever of the deck paper supply position sensor, causing the lifter
to move farther down until the stack of paper moves past the sensor lever.
The lifter repeats its descent operation each time paper is added until the deck lifter lower limit detecting switch
(SW102) is pushed (maximum paper supply position).

Chapter 2
The host machine' s DC CPU monitors the timing at which sensors associated with deck lifter operation go on; and,
if the deck paper supply position sensor (PS107) is '0' when the deck lifter position sensor (PS104) and the deck level
sensor (PS108) are '1' (not a normal combination), it will indicate an error code (E041) on the host machine' s control
panel.

2.5 Opening /Closing the Compartment
Chapter 2
2.5.1 Opening/Closing the Compartment
0003-2823
1. Opening/Closing the Deck
When the deck open switch (SW100) is pushed, the deck open solenoid (SL102) goes on to free the lock on the deck
(compartment); as a result, the deck is pushed several centimeters to the front by the work of a spring. At the same
time, the deck lifter motor (M102) starts to rotate to move down the lifter inside the deck.
When the deck (compartment) is pushed into the host machine, the deck open sensor (PS109) detects the light
blocking plate, permitting the lifter to move up as far as the pickup position.
When the deck lifter motor rotates to open/close the deck, the deck open indicator (LED100) on the open switch PCB
goes on or flashes.

2.6 Detecting Jams
Chapter 2
2.6.1 Overview
0003-2825
The side paper deck is equipped with the following 2 sensors used to find out whether or not paper is moving
smoothly. The machine checks for the presence of a jam at such times as initiated its DC controller PCB and with
reference to the signals from these sensors. When the machine's DC controller PCB identifies a jam, it discharges
sheets ahead of the jam and stops the ongoing operation, after which it will indicate jam removal instructions on its
control panel.

The urethane sponge used on the deck separation
roller is pink in color immediately after foaming;
changing the color to orange and then to yellow
(accelerated if exposed to light).
This is a general characteristic of the urethane
sponge, and there is no difference in performance
because of discoloration. (The part does not come
in different types, as according to color.)

4.2.1.3 Adjusting the Height of
the Side Roll
Before Making the Adjustments
1. Detach the machine from its host machine, and then
attach it back again, thereby checking if the machine
becomes unstable in response to the impact.
If the machine becomes unstable, adjust the height of
the side roll as follows. Otherwise, these adjustments
are not needed.
Making Adjustments
1) Connect the machine to its host machine.
2) Remove all paper from inside the deck.
3) Remove the 3 screws [1], and detach the right cover
[2].

5) While keeping the side roll in contact with th floor,
tighten the fixing screw.At this time, refer to the index
so that the left and right screws are at the same index.
6) Detach the machine from its host machine, and then
attach it back on.If it can be attached and detached
without extra force, put back the machine's right cover
and the paper previously removed to end the
adjustment work.If attachment and detachment
requires extra force, on the other hand, go through the
following:

4.2.1.4 Stringing the lifter
Wires
1) Check to make sure that the lifter drive shaft [1] and
the lifter [2] are fixed in place using a hex wrench
[3] and 2 long screwdrivers [4], respectively.
2) Fix the 4 cable fixing plates [5] in place to the lifter
using 2 screws each.
3) Hook the lifer cable [6] on the 4 pulleys [7] above.
4) Hook the ball of the lifter cable on the 2 front/rear
pulleys [8] of the lifter drive shaft; then, wind it
about 1.5 times along the groove of the pulley.
At this time, be sure to keep the lifter cable taut so that
the long drivers used to keep the lifter are slightly
lifted by the cable.
5) Fix the 2 pulleys [5] in place to the lifter drive shaft
with a set screw [9] (1 pc. each).
6) Fit all removed pulleys to the lifter shaft; then,
measure the height A from the base plate of the
compartment to the top face of the lifter, thus
making sure that the lifter is level.

Replacement
4.2.2.1 Adjusting the Position
of the Deck Pickup Roller
Release Solenoid (SL101)
Before detaching the deck pickup roller release
solenoid [1] from the support plate, take note of the
position of the 2 fixing screws [2] with reference to
the index on the support plate (or, mark the position on
the support plate using a scriber).
When mounting the solenoid on its own, be sure that
it is mounted back to where the previous solenoid was
before removal.
