relationship between electrical and mechanical systems with reference to the timing of
operation.

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 eld. 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.

improvement or other purposes, and major changes will be communicated in the form of

Overview of Electrical Circuitry
The nisher's sequence of the operation is controlled by its nisher controller PCB.
The nisher controller PCB has the 16-bit CPU, and the controller also controls the
communication with the host machine in addition to controlling the nisher's operation
sequence.
The CPU on the nisher controller PCB contains a ash ROM used to store the operating
sequence program.
The nisher controller PCB uses the serial communication line to receive various commands
from its host to drive the motors. It also uses serial communications to send information on
the sensors and switches to its host.

Stacking Operation
The paper delivered from the delivery roller is stacked on the processing tray and the paper is
aligned in the feed direction.
How paper is delivered from the delivery roller and stacked on the processing tray is
described below.
(1) When two or more sheets with a length of 150 mm or more are stacked, the tray
auxiliary guide motor (M6) operates after lapse of the specied time since detection of
paper by the Buffer Sensor (S1), thus sliding out the tray auxiliary guides.

(2) After the specied time has lapsed since paper has passed through the Feed Path
Sensor (S2), the paddle motor (M3) operates to rotate the paddle once to stack the
paper on the processing tray.
The stacked paper is pressed against the stopper by the paper return paddle which is
driven by the delivery motor (M2), thus aligning the paper in the feed direction.

Tray Auxiliary Guide Operation
When two or more sheets with a length of 150 mm or more are stacked on the processing
tray, the tray auxiliary guides slide out to prevent misalignment of paper due to curl.
The tray auxiliary guides are driven by the tray auxiliary guide motor (M6). They slide out
when the inlet Buffer Sensor (S1) detects paper and they slide back when paper is delivered
by the gripper.
The home position of each tray auxiliary guide is detected by the Tray Auxiliary Guide HP
Sensor (S6).

The tray auxiliary guide slide-out amount varies depending on the operation mode and paper

Alignment / Shifting Operation
The paper stacked on the processing tray is aligned in the width direction by the front and
rear alignment plates. Then, the paper is shifted to the position where it is delivered to the
stack tray.
The front alignment plate is driven by the front alignment motor (M4) and the rear alignment
plate is driven by the rear alignment motor (M5). The home positions of the front and rear
alignment plates are detected by the Front Alignment Plate HP Sensor (S4) and Rear
Alignment Plate HP Sensor (S5).

• If the number of sheets stacked is 1 to 3: 2.0 mm
• If the number of sheets stacked is 4 or more: 4.0 mm

Staple Operation
When the staple mode is selected, paper is stapled by the stapler after it has been stacked
on the processing tray and aligned.
The stapler is provided at the front of the nisher. Paper is stapled at only one position at the
front.
A maximum of 30* sheets can be stapled.
NOTE:
When the following service mode value set 1, the stapling capacity becomes 50 sheets.
To set the maximum number of sheets to be stapled in the Finisher.

Stack Delivery Operation
The paper stacked on the processing tray is delivered to the stack tray by the gripper after
being shifted and stapled.
The gripper is driven by the gripper motor (M7) via the gripper drive belt.
The home position of the gripper is detected by the gripper HP sensor (S7).

Stack Tray Paper Retainer Operation
The paper delivered to the stack tray is retained by the stack tray paper retainer to prevent
wrong detection of paper height and misalignment caused by curl.
The tray paper retainer is released when the gripper presses portion A of the gear stopper
after it has delivered paper to the stack tray. Then, it is rotated by the driving force of the
gripper motor (M7).

Stack Tray Shift Operation
The paper delivered from the processing tray by the gripper is then stacked on the stack tray.
The stack tray is moved up and down by the stack tray shift motor (M8).
When the power is turned on or before start of printing, the stack tray shift motor (M8) is
driven to move the stack tray up/down to the position where the stack tray paper height
sensor (S9) detects the stack tray top surface.
After the paper has been delivered from the processing tray, the stack tray moves down by
the specied amount. Then, the stack tray moves up until the stack tray paper height sensor
(S9) detects the stack tray top surface (top surface of the stacked paper) with the stack tray
paper height sensor ag.

Stack Tray Paper Height Detection Control
The height of the paper stack on the stack tray is detected by the stack tray paper height
sensor (S9).
After paper has been delivered to the stack tray, the stack tray moves down by the specied
amount.
Next, the stack tray paper height sensor (S9) turns on (the top surface of the paper on the
stack tray is detected).
The above operations are repeated each time paper is delivered to the stack tray.
