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.

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 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 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.

Points to Note About Turning Off the Main Power Switch
This machine has two switches related to power supply, the Power switch and the breaker.
Turning on the Power switch powers this machine.
The breaker detects an excess current and electric leakage to protect you against an electric shock.
MEMO:
Explain to the customer that the breaker must be checked once or twice a month and the result
must be recorded.

Overview of Electrical Circuitry
The machine's sequence of operations is controlled by the DC controller PCB.
The DC controller PCB is a CPU used to interpret input signals from sensors and host machine and
generate signals to drive such loads as motors and clutches at such times as programmed in
advance.

Various Modes of Control
Outline of operations
When a paper feed signal is received from the host machine after paper is loaded in the tray,
the following three sequences of operations are performed:
1.Sequence of surface insert operation
2.Sequence of back insert operation
3.Sequence of inserter pickup tray switch operation
Sequence of surface insert operation
The following operations are performed when two papers are fed from the inserter paper feed unit.
(1) First paper feeding for separation
- The upper tray lift motor turns in the reverse direction at a speed of 533 pps to move the paper feed
tray upward.
- The upper tray pick sensor turns on to stop the upper tray lift motor.
- For plain paper, the tray paper feed motor turns in the reverse direction at a speed of 500 mm/s
to start separating the paper in the tray. For thick paper, the tray paper feed motor turns in the
reverse direction at a speed of 250 mm/s to start separating the paper in the tray.
- For the upper tray, the tray paper feed motor stops when the paper has been fed 14.7 [mm] since
the registration sensor turned on. For the lower tray, the tray paper feed motor stops when the
paper has been fed 19.1 mm since the registration sensor turned on.
- The upper tray lift motor turns in the normal direction at a speed of 533 pps to move the paper feed
tray 9 pls downward.
