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."

1.3.1 Scheduled Servicing Basic Procedure

iR C3100 / / / iR C3100N / / / / iR C2570 / / iR C3170 / / iR C3170i / iR C2570i

- As a rule, provide scheduled servicing every 60,000 prints.

- Before setting out for a visit, check with the service book, and take parts for which replacement is expected.

- Disconnect the power plug on a periodical basis, and clean it and the area around it with a dry cloth. If left connected for a long time in an area subject to high

0000-9666

humidity or oily smoke, it can catch fire (the buildup of dust is likely to absorb moisture and cause insulation failure).

<Work Procedure>

1) Report to the person in charge, and check the general condition.

2) Record the counter readings, and check the faulty prints.

3) Make the following checks, and clean/adjust the components:

- COPIER > COUNTER > MISC > FX-UP-RL

- COPIER > COUNTER > MISC > DV-UNT-K

1-2

Any of the following indicates that the counter reading is incorrect:
a. the counter reading is lower than that recorded for the previous service visit.
b. the counter reading is excessively high in relation to the increase in the total counter reading recorded for the previous service visit.

If the counter reading is faulty, make the following computation, and enter the result:
A = current reading of 'total 2'.
B = reading of 'total 2' recorded for the previous service visit.
C = reading of 'FX-UP-RL' or 'DV-UNIT-K' recorded for the previous service visit.

Enter the result of the following for 'FX-UP-RL' or 'DV-UNIT-K':
(A - B) + C

4) Check the following item, and clean/adjust the parts as necessary.

Item to check

Test Copy image density standards

soiling of white background

clarity of characters

margin

fixing incorrect registration, soiling of back of paper

margin standards (singe-sided print) leading edge: 2.5 +/-1.5 mm

(double-sided print) leading edge: 2.5 +/- 2.0 mm

Laser Exposure System dust-blocking glass cleaning tool

Feeding System registration upper/lower roller

paper lint in front of registration assembly

5) Check the waste toner case.

If the case is half full, dispose of the waste toner in a plastic bag for collection. Or, replace it with a new one.

Cleaning the primary charging roller involves rotating the drum manu­ally. Be sure of the following during the work:

- Do not touch the imaging area of the drum surface. The presence of

finger prints or oils can cause cracking of the surface. Whenever
possible, try washing the hands before starting the work.

- Be sure to rotate the drum in the correct direction. Go over the

following, and make sure not to rotate it in the wrong direction.

Be sure to use paper under the drum unit to prevent adhesion of dust.

1) Insert paper through the gap under the primary charging roller cover [1],

all the way until it stops.

F-1-6

Do not touch the imaging area [A] (shown in moss green) of the
drum surface. The presence of fingerprints or oils will cause cracking
of the drum surface.

F-1-3

Be sure to perform step 1) without fail to protect the drum from

scratches and external light.

2) Free the 4 protrusions [1], and detach the primary charging roller cover
[2].

3) Dry wipe the primary charging roller [1] with lint-free paper. Be sure to

F-1-4

move the paper in axial direction and in one direction.

F-1-7

Be sure to pay attention to the direction of drum rotation. Do NOT
rotate it counterclockwise when viewing the drum unit from the
front. If you inadvertently started to turn it in the wrong direction,
stop immediately; then, put the drum unit back into the machine,
generate a halftone image, and check to see that the output is free of
image faults.

5) Repeat steps 3) and 4) to clean the entire surface of the primary charging
roller.

If subjected to light for a long time, the drum will deteriorate. Be sure to

work briskly (e.g., within 5 min or less).

When removing the primary charging roller cover, be sure also to keep
paper between the primary charging roller and the drum as you did when
removing the cover. Remove the paper after you have attached the cover.

4) Hold the end of the drum [A] (i.e., non-imaging area, shown in beige);
then, turn the drum in the direction of the arrow (clockwise direction

1) Draw a mark-off line at the attachment position of the primary transfer

roller holder. At this time, care should be taken to draw the line precisely
because the primary transfer roller holder is attached back based on the
line.

Note 3:
The arrow in the figure indicates the direction of paper movement.

Note 4:
The nip tends to increase as more and more paper is moved past. There is no
need, however,
for another session of adjustment each time 5000 sheets have been moved
past. If
adjustments are needed for some reason, try so that b and c are adjusted to
match the median
value of 9.25 mm.

6) If the nip width is not as indicated, perform the following:
6-1) Turn the front and rear adjusting screws to adjust the nip.

EX: if the median value of the nip measurements is closer to the lower limit,
tighten the screw of the side where the nip at the ends is smaller; a full turn

of the screw will

cause a change of about 0.5 mm.

EX: if the nip balance is correct, turn the screws of both sides.
