1 Basic Operations

1.1 Specifications

The finisher serves to deliver sheets coming from its host machine. The mode of delivery may be non-sort stack, job offset*, or staple delivery.

The saddle unit built into the finisher is used to fold a stack of sheets coming from the finisher unit in half for delivery.

All these operations are controlled by various commands sent by the host machine in addition to the commands from the finisher controller PCB.

The puncher unit (option) is designed for installation to the pickup assembly of the finisher, and is used to punch holes in sheets coming from the host machine.

The above operations are controlled with various commands from the finisher controller PCB as well as the commands from the punch controller PCB.

CHAPTER 2 OUTLINE OF OPERATION

1.2 Outline of the Electrical Circuitry

The sequence of finisher operations is controlled by the finisher controller PCB. The finisher controller PCB is a 16-bit microprocessor (CPU), and is also used for combination with the host machine (serial).

The finisher controller PCB drive motors and other loads in response to the various commands from the host machine. It also communicates such data as on the states of various sensors and switches to the host machine by way of the serial communication line.

	The ICs mounted to the finisher controller PCB have the following functions:
•	IC13 (CPU)	•	IC11 (communication IC)
	Controls sequence of operations.		Communicates with the host machine.
•	IC12 (EEP-ROM)	•	IC1 (regulator IC)
	Backs up adjustment settings.		Generates 5 V.

•IC6 (EP-ROM)

Stores sequence programs.

2 Feed/Drive System

2.1 Outline

The machine performs the following in response to the commands coming from its host machine on the sheets arriving from the host machine for delivery: simple stacking, job offset, and stapling or folding (in two).

If a punch unit (option) is installed, the sheets are pouched and delivered to the delivery tray.

Sheets may be delivered in either of five ways (including one for the puncher unit):

b. Job Offset

The machine pulls the sheet once to the processing tray. It then moves the sheet to the front or the rear using the aligning plate. When it has deposited a specific number of sheets, it delivers them in the form of a aligning plane. When the number of sheets stacked on the processing tray reaches a specified value, the sheets are delivered in a form of a stack. Even if the specified value is not reached, stacked sheets are temporarily delivered when 10 sheets of large-size paper (300 mm or longer) or 30 sheets of small-size paper (299 mm or shorter) have been stacked. (5- and STMT-sizes: 10 sheets)

2.2 Feed/Delivery

2.2.1 Outline

The machine forwards the sheets coming from its host machine to the delivery tray, processing tray, or saddle unit according to the type of delivery used. The sheets forwarded to the processing tray or the saddle unit are offset, stapled, or folded.

F02-202-01 shows the motors that are associated with moving and aligning sheets. These motors are controlled (rotated clockwise or counterclockwise) by the microprocessor (CPU) on the finisher controller PCB.

The paper path is equipped with the sensors shown in T02-202-02 used to monitor the arrival or passage of sheets.

If a sheet fails to arrive at or move past a specific sensor within a specific period of time, the finisher controller will assume a jam, and stops the ongoing operation and, at the same time, communicates the presence of a jam to the host machine.

CHAPTER 2 OUTLINE OF OPERATION

2.3 Job Offset

2.3.1 Outline

"Job offset" refers to the operation by which the machine delivers a set of sheets with them pulled forward or backward for sorting.

Switching between the forward and backward directions is made using an aligning plate (front) and an aligning plate (rear).

The sheet coming between the delivery rollers is fed onto the processing tray and then fed toward the stopper by the paddle.

A swing guide is at the up position while a sheet is being pulled onto the processing tray or during alignment. It is at the down position during stack feeding, stack delivery, or stapling.

At power-on, the finisher controller PCB drives the aligning plate (front) motor (M4) and the aligning plate (rear) motor (M5) to return the two aligning plates to their home positions.
