CHAPTER 1 GENERAL DESCRIPTION

I. FEATURES

1. Small in Size, Light in Weight

 The finisher is designed as a small, light delivery device.

2. Mono-Frame

 The finisher is cased in a mono-frame, which has enabled reduction of the number of covers.

3. Sorting and Stapling by Stack Offset

 The finisher puts together stacks of sheets on its intermediary processing tray for offset

sorting and stapling.

4. Stack Tray

 The finishers stack tray is capable of holding as many as 1,000 sheets of small-size paper or

15 sheets of large-size paper. Further, it can hold as many as 30 sets of stapled stacks (each consisting of up to 30 sheets).

CHAPTER 2 BASIC OPERATION

B. Outline of Electrical Circuitry

The finishers operation sequences are controlled by the finisher controller PCB, which is a 32-

bit CPU. The finisher controller PCB is also used to control communication (serial) with the copier.

The CPU on the finisher controller PCB is equipped with a built-in ROM used to store

operation sequence programs.

The finisher controller PCB drives motors in response to various commands coming from the

copier through serial communication lines. On the other hand, it communicates the state of each sensor and switch to the copier in serial mode of communication.

The ICs on the finisher controller PCB have the following functions:

n Q1 (CPU; w/ built-in flash ROM)

Controls sequence. Stores sequence programs.

n Q2 (communication IC)

Communicates with the copier (IPC II).

n Q8 (regulator IC)

Generates 5 V used to drive sensors and logic system.

CHAPTER 2 BASIC OPERATION

II. BASIC OPERATIONS

The finisher is designed to operate as follows:

1. Paper arrives from the copier.

Figure 2-201

2. Paper reaches the intermediary processing tray.

Figure 2-202

2-6

CHAPTER 2 BASIC OPERATION

3. Paper is moved until it butts against the stopper plate by the work of the returning roller.

Figure 2-203

4. The paper is put into order by the work of the front/rear jogging plate.

Figure 2-204

2-7

CHAPTER 2 BASIC OPERATION

5. Operations 1 through 4 are repeated until a specific number of sheets have been stacked on the intermediary processing tray.

6. The sheets are stapled. (If stapling is selected.)

Figure 2-205

7. The stack on the intermediary processing tray is moved to the stack tray.

Figure 2-206

CHAPTER 2 BASIC OPERATION

III. FEEDING DRIVE SYSTEM

A. Outline

Paper coming from the copier is sent to the intermediary processing tray, on which it is put into

order and offset/stapled for delivery to the stack tray.

The machine detects jams using the inlet sensor (S2). Figure 2-301 shows the construction of the feeding drive system.

B. Delivery

Paper coming from the copier is sent to the intermediary processing tray by the work of the

delivery motor (M1), and the movement of paper is monitored by the inlet sensor (S2).

The delivery slot of the machine is equipped with a feeding guide (A/B). The feeding guide A/ B holds down the trailing edge of paper using its own weight so as to help move paper as far as the returning roller.
