1.1 Installation
Precautions during installation
All important adjustments were made to this equipment prior to it being packed
and shipped from the fa ctor y, and it has als o bee n su bj ect to a thoroug h i nsp ect ion.
The installation procedure is extremely important to ensure that the equipment
performs mechanically in accordance with the ratings acquired during the inspection process after it has been unpacked by the customer.
The service engineers must therefore have a full understa nding of the mechanical
capabilities of this equipment, and it must be installed in a favorable environment
in accordance with correct procedures.
Location of installation
Ensure that the location of installation satisfies the following conditions. It is recommended that an area that meets these conditions is determined prior to the unit
being delivered to the customer.
Power supply
FEATURES
Installation
Prepare a power supply that conforms to the following:
•
Current (AC)
•
Supply frequency
Operating environment
Ensure that the location of installation conforms to the following:

• Avoid installation in the following locations.
Areas where the device will be subject to direct sunlight.
•
If this is unavoidable and the device must be installed in an area where it is subject
to direct sunlight, ensure that a thick curtain or other form of protection is used to
deflect the sunlight.

Procedures for unpacking and installation
There are cases where water droplets will form on the surface of metal fittings
when brought into warm places from cold places. This is known as condensation,
and using equipment on which condensation has formed may result in faults arising with the feeder assembly. To avoid this, do not unpack the device for at least
one hour after it has been brought in from a cold place to allow it to become accustomed to room temperature.
Unpacking the finisher
Remove the outer box in which the finisher is packed.
1
Remove the accessories. Confirm that the accessories include the power sup-
2
ply cord, the manual, the guide rails, the trays, the earth adapter and the
interface cable.
Remove the upper pads (left and right) and lift the finisher out of the box.
3
Remove the vinyl bag in which the finisher is packed and then peel off the
4
tape that holds each part in place. Verify that the covers were not scratched,
bent or otherwise damaged during transportation.
Open the front cover and remove the two spacers.
5
Attach the trays to the finisher with the screws.

OPERATION THEORY
General
2.1 General
This chapter provides explanations on the purpose, role and mechanical system of
each function, as well as providing an outline of the operational timing of each part
by function.
The descriptions of the digital circuits for this device include signals names without slashes (“/”) for H and PSNS electrical signal levels, and signal names with
slashes, such as L and /SCNON.
H and other signal names without slashes (“/”) are true (indicating that the signal
has been output) at the supply voltage level and false (indicating that the signal
has not been output) at the G ND leve l. L and other s ignal s name s wit h sla she s are
true at the ND level and false at the supply voltage level.
This device uses a microcomputer. However, as it is impossible to run an internal
operation check on a microcomputer, the explanation for the microcomputer operations has been omitted.
Also, as it is a pre-requisite for the internal printed circuit board to be untampered
with by the customer, simple summaries with the use of block diagrams have been
used in this manual to cover the descriptions of these printed circuit boards. Owing
to this, the explanations for circuits only cover the two areas from the sensors to
the input areas of the main substrates and from the output area of the main substrates to the load, and block diagrams are used to explain each function.

2.2 Basic operations
Outline
The finisher performs the face-down ejection and face-up ejection of paper fed
through from the printer. The job offset and stapling functions are available with
face-down ejection.
These operations are controlled by the finisher driver’s circuit board.
OPERATION THEORY
Basic operations
Figure 2.1
Outline of the finisher
Outline of electrical circuits
The finisher’s operational sequence is controlled by the finisher driver’s circuit
board. A 16-bit microcomputer (CPU) is used in the finisher driver’s circuit board,
and this performed serial communications with the sequential control.
The finisher driver operates the solenoids and motors, etc., in accordance with the
various commands that are transmitted from the option controller via the serial
communications line. The finisher driver also notifies the option controller of sensor and switch information via the serial communications line.
The major roles of the ICs mounted in the finisher driver are as follows.
Q1 (CPU). Sequential control.
•
Q2 (EP-ROM). Sequential programs built in.
•
Q3 (RAM). Used for backing up the initial data.
•
Q4 (IPC). Used for communications control.
•
The diagram below shows the signal flow between the finisher and the printer.
