I. FEATURES

1. Uninterrupted copying work. The two bin modules are operated independently of each other, enabling uninter-rupted copying work.

2. Shorter stapling time. The bins are divided into two groups (upper/lower), shortening the processing time

through simultaneous sorting and stapling.

3. Three modes of auto stapling. In staple sort mode, the copies delivered to the bins may automatically be stapled

either at the front (single), rear (single), or both front and rear (double)as many as100 sheets may be stapled (98 sheets of 80 g/m2 + 2 sheets of 200 g/m2).

4. Easier jam removal. A jam may be removed from the front without having to separate the machine from

the copier. The bins may be moved up or down by a press on a switch, making removal of a jam

between a bin and the feeding assembly very easy. The finishers display shows instructions on how to remove jams.

5. Better paper feeding. Paper as thick as 200 g/m2 may be fed.

6. Easier access to copies.

The stacker may be drawn to the front, providing easy access to the deliveredcopies.

7. Folding function (accessory). Installation of the Paper Folding Unit-A1 (accessory) will enable folding copies of A3,

A4, or 279.4 431.8 mm (11" 17") in Zs. (Paper must be of 64 to 80 g/m2).

9. Paper Jam at the Rear of the Sort

BinAt times, paper gets trapped at the

rear of the bin (finisher) and cannot beeasily removed. If such is the case,perform the following steps to remove thepaper jam.

1) Press [NEXT STEP] key on the dis-play.


3) Find out the interval of the bins andthe position of the bin in question. If the jam is farther up than the closeinterval bins,

Press the key so that the bin inquestion will lower to the wide

interval bins.

Be sure to close the bin cover.Otherwise, you cannot move thebins.

Caution:

Jammed paper

CHAPTER 2

OPERATIONS AND TIMING

In outline diagrams, represents mechanical drive paths, and indicates electrical sig-

nal paths.

Signals in digital circuits are identified as 1 for High and 0 for Low. The voltage of signals, how-ever, depends on the circuit.

Nearly all operations of the product are controlled by a microprocessor; the internal workings of the

processor are not relevant to the servicemans work and, therefore, are left out of the discussions. By

the same token, no repairs are prescribed for the PCBs at the users premises; for this reason, PCBs

are discussed by means of block diagrams rather than circuit diagrams.

For the purpose of explanation, discussions are divided into the following: from sensors to DC con-

troller PCB input ports; from DC controller output ports to loads; and minor control circuits and functions.

I. BASIC CONSTRUCTION

A. Functional Construction

The finisher may be broadly divided into nine functional blocks: control panel,common feeding drive system, upper feeding drive system, lower feeding drive system,stack processing drive system, stacker drive system, upper bin module drive system,lower bin module drive system, and control system.

B. Outline of the Electrical Circuitry

The finishers electrical mechanisms are controlled by the finisher controller PCB.

The major functions of the IC on the finisher controller PCB are as shown in Table 2-101.The finisher is equipped with two CPUs (IC1, IC8) used to control operating sequences,each with its own areas of control, and both ICs use a communication IC to controlvarious operations.

E. Communication between Copier and Finisher

1. Outline

The finisher exchanges status signals with the copier in IPC communication mode(using communication ICs).

The status signals are first written in RAM on the finisher controller PCB, and are sentout in response to control signals from the IPU (IC1).

When an error occurs in IPC communication, the copiers self diagnosis function turnson to indicate E500 or E713 on the copiers control panel. (E501 represents acommunication error within the finisher.)

The finishers IPC communication may be either IPC communication or IPCcommunication 2, which provides a faster means of communication than the former.

II. BASIC OPERATION

A. Outline

The finisher sorts, staples, or stacks the delivered copies according to the modeselected on the copiers control panel, operating in either of the following three majormodes:

1. Non-sort mode2. Sort mode3. Staple sort mode

1. Non-Sort Mode

The copies are delivered to the non-sort tray, and are not sorted.

3. Circulating the Original

The finisher is equipped with two modules, each consisting of six bins. Each bin

module is capable of operating independently of each other so that six groups of copiesmay be handled for each set.

When as many as six groups of copies must be processed, the finisher at times wouldcontinue to operate after the copier finishes operation. To limit the period of such a typeof operation, the originals are circulated for specific numbers of times as noted in Table2-201, so that the last original is circulated for, whenever possible, fewer than two setsof copies.
