1.1Features

Large-volume paper ejection

Tray No.1 has a capacity large enough to hold approximately 600 pieces of paper (64g/m2), and anything up to 700 pieces of paper (64g/m2) can be loaded into trays No.2 and No.3.

Job offset

The printer is equipped with a job offset function. The first page only or whole set of pages (default) of each job is placed aside during ejection, and the paper loaded into the trays can be separated into groups.

Stapler function

A control signal transmitted from an external source enables staples to be set at two locations in the center of the paper, at one location at the left-hand corner or at one location at the right-hand corner depending on the size of the paper.

Installation

1.1Installation

Precautions during installation

All important adjustments were made to this equipment prior to it being packed and shipped from the factory, and it has also been subject to a thorough inspection. 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 understanding 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

Prepare a power supply that conforms to the following:

•Current (AC). Rated current ±10%

•Supply frequency. 50/60Hz ±2Hz

Operating environment

Ensure that the location of installation conforms to the following:

•A flat and horizontal surface

•Temperature and humidity ranges must be within the following:

•Surrounding temperature. 10 to 32.5 degrees Celsius

•Surrounding humidity. 20 to 80% RH (relative humidity) without condensation

•Areas which are well-ventilated and not subject to steam.

•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.

•Areas near magnets or where magnetic fields exist.

•Areas that are subject to vibrations.

•Areas in which dust collects.

•Near to open flames and moisture.

Installation space

Install the device at a suitable distance from walls and other obstructions, and secure enough space to enable easy operations.

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

1Remove the outer box in which the finisher is packed.

2Remove the accessories. Confirm that the accessories include the power supply cord, the manual, the guide rails, the trays, the earth adapter and the interface cable.

3Remove the upper pads (left and right) and lift the finisher out of the box.

4Remove the vinyl bag in which the finisher is packed and then peel off the tape that holds each part in place. Verify that the covers were not scratched, bent or otherwise damaged during transportation.

5Open the front cover and remove the two spacers.

6Attach the trays to the finisher with the screws.

General

2.1General

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 GND level. L and other signals names with slashes 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.

Basic operations

2.2Basic 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.

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.
