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."

1.1.1 Selecting the Site of Installation 0002-6395
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
Be sure that the site of installation satisfies the following requirements; if possible, visit the user's before delivery of
the machine:
- There must be a properly grounded power outlet that is rated as indicated (+/-10%) and that may be used exclusively
by the machine.
- The temperature of the site must be between 15 and 30 deg C and humidity, between 25% and 80%. The machine
may not be installed near a water faucet, water boiler, humidifier, or refrigerator.
- The site must not be near a source of fire or in an area subject to dust or ammonium gas. If the area is exposed to
the direct rays of the sun, the windows must be furnished with curtains.
- The site must be well ventilated. However, the machine must not be installed near the air vent of the room. The
ozone generated by the machine while in operation is not of a level that can harm the health of the individuals around
the machine. Nevertheless, some may find it to be unpleasant, and the room must be ventilated often.
- The machine must be placed on a level floor so that all its feet remain in contact with the floor and the machine will
remain level.
- There must be enough space around the machine. The following diagram shows the minimum dimensions;
whenever possible, be sure there will be more space than indicated:
- Copier [1]

- The machine will be placed on the side of the slope plate having a pin hole [1]. Be sure that the space will be on
this side (left side).
The side of the slope plate having a pin hole (left) is where the delivery side of the machine will be, with the front of
the machine facing the side indicated by the arrow.

1.2 Unpacking and
Installation
1.2.1 Before Starting the
Work 0002-6409
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
Keep the following in mind when installing the
machine:
1. When a machine is moved from a cold to warm
location, condensation can occur in its pickup/feeding
assembly, ultimately causing image faults. As
necessary, leave the machine alone for at least 1 hour
without unpacking, and start the work when it has
fully become used to the room temperature.
(The term "condensation" refers to a symptom in
which droplets of water occur on the surface of a
metal object brought in from a cold to warm location
as the result of rapidly cooling vapor around it.)
2. The machine weighs about 230 kg. Be sure to work
in a group of 4 persons when lifting it.
3. Be sure to turn the 2 adjusters (front) found on the
bottom of the machine clockwise to release them.
These adjusters can slip off the machine when the
machine is moved. Take care not to lose them.
1.2.2 Unpacking the
Machine 0002-6411
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
1) Open the shipping box, and remove the plastic
covers.
2) Fit the 2 included grips [2] into the grip slots [1]
found on the pickup side of the machine.
F-1-6
3) While holding the grips on the pickup side (front,
rear), lift the machine slightly, and remove the pad [1]
in the direction of the arrow.
(weight of the machine: about 230 kg)
F-1-7
4) While holding the grips on the delivery side (front,
rear), lift the machine slightly, and remove the pad [1]
in the direction of the arrow.
At this time, do not lift the machine more than
necessary. Otherwise, you can lose the balance.

then, match the skid and the slope plate by their pin
holes, and fit the pin [2] (1 pc. each).
F-1-10
Check to make sure that the caster [1] has not rolled
off the skid [2]. Also, be sure that it has not ridden
over the edge [3] of the skid.
F-1-11
8) While holding the grips on the delivery side of the
machine, move the machine along the slope plates and
off the skid.
9) Remove the packing tape from the machine.
10) Remove the 2 grips from the pickup side.

Assembly 0002-6414
iR C6800C / iR C6800CN / iR 5800C / iR 5800CN
1) Detach the 3 shipping tags [1] from the right rear
lower cover.
F-1-19
2) Open the upper right cover [1] and the lower right
cover [2]; then, remove the 3 unlocking spacers [3]
from the pickup slot of the right deck and the
cassettes.
F-1-20
To detach the release spacer, be sure first to push its
lever [1] in the direction of A before pulling it in the
direction of B. Pulling the lever [1] of the release
spacer horizontally by mistake can damage the pickup
assembly. Take full care.
F-1-21
3) Close the upper right cover and the lower right
cover.
4) Push the release button, and slide out the left deck.
The left deck is not supported by its locking plate, and
the deck assembly may not slide out in response to a
press on the release button. If so, slide out the deck
assembly by hand.
5) Open the front cover.
6) Match the included left deck locking plate [1]
against the 2 holes in the left deck rear side plate; then,
secure it in place using a screw (RS tightening; M4x8)
