Introduction
The following rules apply throughout this Service Manual:
1. Each chapter contains sectio ns explai ning the purpose of specific fu nctions a nd the rela tionshi p between el ectrical
and mechanical systems with reference to the timing of operation.
In the diagrams, represents the path of mechanical driv e; where a signal name accompanies the sy mbol,
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 mach ine 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 inte rnal mechanisms o f a microproce ssor cannot be ch ecked in the field. Therefore , the
operations of the micropr ocessors used in the machines are not discussed: they are explaine d 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 ch ange without notice for product improvement or oth er
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.

2.2 Basic Operation
2.2.1 Shift Movement
0003-8687
The machine moves the tray to the front an d the rear (shift of 55 mm) to sort stacks (offset). The tray is driven by a
DC motor, and the rotation of the motor is converted into liner movement by means of a rack and pinion gear
mechanism. The location of the tray (front, rear) is monitored by the HP sensor mounted to the front and the rear.

2.2.2 Placement of Paper
0003-8689
The machine's tray is held up by the work of a coil spring . Wh en paper is placed, the tray moves down under the
weight of the paper. The height of the stack in the tray is monitored by the tray full sensor (reflection ty pe photo
sensor), and the shift tray driver PCB sends the tray full si gnal to the h ost machine when the t op of the stack re aches
a specific height.

closer to the paper, and fix it in place where ‘ON’ is
indicated.

Memo: If ‘ON’ is not indicated after moving the
sensor closest to the paper, keep adding a sheet of
paper until ‘ON’ is indicated.
1. When moving the sensor (front, rear), be sure to do
so starting from where it is farthest from the paper.
This is important in respect of the characteristics of
the sensor.
2. Be sure that the grounding terminal of the sensor
(front, rear) is parallel to the sensor and, moreover, its
bend is in downward direction.
