Use of this manual should be strictly supervised to avoid disclosure of confidential information.
Symbols Used
This documentation uses the following symbols to indicate special information:
Symbol Description
Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.
Indicates an item requiring care to avoid electric shocks.
Indicates an item requiring care to avoid combustion (fire).
Indicates an item prohibiting disassembly to avoid electric shocks or problems.
Introduction
Memo
REF.
Indicates an item requiring disconnection of the power plug from the electric outlet.
Indicates an item intended to provide notes assisting the understanding of the topic in question.
Indicates an item of reference assisting the understanding of the topic in question.
Provides a description of a service mode.
Provides a description of the nature of an error indication.
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."

1.3.2 Warning and Action to Take
If the original placement indicator starts to flash while an original is being moved, suspect a jam, and go through the
following:
1) Check all originals in the tray.
2) Open the feeder cover, and remove any jammed original.
3) Put the originals in order starting from 1st to last page, and place the stack back in the ADF.

2.1.1 Overview of the Electrical Circuitry
0002-7181
The machine is not equipped with a controller PCB, and its electrical mechanisms are controlled by the reader
controller PCB, which serves as a CPU (IC1). The CPU interprets signals from sensors and the host machine to
generate signals used to drive DC loads (e.g., motor, solenoid) with the help of the CPU (IC9) of the ADF driver PCB.

2.2.2 Overview of Operation Modes
MEMO
The machine executes the following 4 types of operation mode, executing individual modes according to the
instructions from the host machine for printing. The following table shows these operation modes, outlines of the
modes, and corresponding printing modes:

executes idle feed to find out
the size of the original; then,
executes idle feed so that the
reading may start with the

picks up, reverses, and
delivers it after it has been
read.

MEMO
The machine executes idle rotation for a mix of sheets of the same configuration only if it identifies the paper in the
tray at the beginning of the copy job as being LGL.
A sheet of paper is identified as follows in terms of size:
small-size: B6, A5, A4, B5, LTR, STMT
large-size: A4R, B5R, A3, B4, LTRR, LGL, 279.4X431.8 mm (11x17)

2. High-speed Duplex Mode
In addition to the conventional duplexing operation (face -> back -> idle rotation ->delivery), the machine is
equipped with a mechanism referred to as "high-speed duplexing, " in which 2 sheets of paper are reversed inside its
paper path.
The high-speed duplexing operation is exclusively for A4/LTR, and the machine handles the originals at a speed of
35 ipm (If in low-speed duplexing, 25 ipm).
The high-speed duplexing mechanism may be enabled or disabled in service mode:
DISPLAY>FEEDER>OPTION>SL-DBL (0: high-speed duplexing mode (default); 1: low-speed duplexing mode).
If the user tends to use originals not suited to high-speed duplexing mode, be sure to select low-speed duplexing mode
using the foregoing service mode item. The following shows the flow of originals in high-speed duplexing mode:
