to operate the sorter.

Chapter 2 “Operations and Timing” discusses the sorter’s mechanical and electrical systems by

function and various timing of operation.

Chapter 3 “Mechanical System” shows how to disassemble, assemble, and adjust the sorter. Chapter 4 “Maintenance and Inspection” gives lists of periodically replaced parts and consumables/

durables and a scheduled servicing chart.

Chapter 5 “Troubleshooting” shows how to troubleshoot possible faults and gives electrical parts

arrangement diagrams, VR/LED/check pin diagrams by PCB, and self diagnosis tables.

In addition to the above chapters, this Service Manual contains an Appendix consisting of a general timing chart, a signals/abbreviations list, communications signals list, a General circuit diagram controller circuit diagrams, special tools list, and solvent/oils list.

For installation, refer to the Installation Procedure that comes with the Sorter Mounting Kit.

1. GENERAL DESCRIPTION

I. FEATURES

1. Light-weight, compact design

In comparison with the existing 20-bin stapler sorters, the size, weight and number of components of this model have been remarkably reduced, while securing the loadability over equivalence to the former models. Reliability and serviceability have been also improved.

2. Applicable to multiple types of copiers

Straight path communication system of this model allows it to be adapted to multiple types of copiers.

(Communication can be switched between the new and former IPCs. Allowable speed range is 20 ~ 60 cpm.)

D. Communication between copier and sorter

1. Outline

The copier and sorter send status signals back and forth between them through the IPC (IC for

communication) communication.

The sorter is provided with both the new and former IPC communication functions, which can be switched over according to the copier to be installed. The functions are changed over by turning ON or OFF the No. 6 dip switch (SW1) on the sorter controller PCB.

These signals are first written into the RAM on the sorter controller PCB and then sent out in response to control signals from the CPU (Q1).

Though a service man cannot check if status signals are properly transferred or not, if signals are improperly transferred, the automatic diagnosis function of the copier is activated and an error code is displayed on the control panel of the copier.

II. BASIC OPERATIONS

A. Outline

The sorter sorts and staples copies delivered to it according to the modes selected on the copier. The delivered copies can be also stapled by operating the operation keys on the copier. Four operating modes as shown below are available.

1. Non sort mode

2. Sort mode

3. Group mode

4. Staple sort mode

1. Non sort mode

The sorter has a cascade stack function. When the number of copies is below 100, all of them are loaded into the first bin but, when exceeding 100, 30 or 25 copies are loaded into each bin depending on the paper size. When the 20th bin is loaded with copies, the sorter and copier stop operation. By removing all copies from the bins and turning ON the COPY START key, copying for the remaining paper is started.

( Whether the number of copies exceeding the maximum loading value of the sorter can be designated or not, number of copies stopping the operation, and the method of resuming the operation vary depending on the specifications of the copier.)

27

2. OPERATIONS AND TIMING

Figure 2-201

2. Sort/group/staple sort mode

The copies are delivered to the sort bins. At this time, the bin units move up and down to sort the copies. When the copies are stapled, copies delivered into bins are stapled.
