2 Outline of the Sevice Manual

This Service Manual contains basic information needed to service the FINISHER - L1 in the field, conducted for the purpose of maintaining its product quality and a specific level of performance.

This Service Manual consists of the following chapters:

Chapter 1 General Description, shows the features and specifications of the machine,

as well as the names of parts and how to operate it.

Chapter 2 Operations and Timing, explains the mechanical and electrical systems of

the machine by function in relation to the principles of operation and timing at which they are driven.

Chapter 3 Mechanical Systems, shows how to disassemble/assemble the machine

and make adjustments.

Chapter 4 Maintenance and Inspection, provides tables of periodically replaced

parts and consumables/durables and a scheduled servicing chart.

Chapter 5 Troubleshooting, contains troubleshooting tables and diagrams of electrical

parts, lists of VRs, LEDs, and check pins by PCB, and an outline of selfdiagnosis. In addition, an appendix is added to offer a general timing chart, list of signals/abbreviations, general circuit diagrams, and PCB diagrams.

The machine comes with an Installation Procedure. Refer to the instructions in the booklet when installing the machine.

2001 CANON INC. 2000 2000 2000 2000 CANON FINISHER-L1 REV .0 SEPT. 2001

The following rules apply throughout this document: As a rule, the descriptions in this documentation are based on the following:

1. As needed, the work of each function and its relationship with electrical and mechanical parts are explained; where applicable, the timing at which associated parts are driven are also outlined. In a diagram, the symbol

indicates a path of mechanical drive; the symbol

accompanied by a notation indicates the flow of an electrical signal. The expression “power-on” means turning on the power switch, closing the front door, and closing the delivery door so that the parts of the machine are supplied with power.

2. In a digital circuit, the state of a signal is indicated by ‘1’ if its voltage level is high and by ‘0’ if low . The level of voltage, however, differs from circuit to circuit. The machine uses a CPU; however, since the internal functions of a CPU is outside the scope of a service person, detailed explanations are omitted from descriptions. In this document, a circuit diagram may cover from sensors to inputs of a controller PCB or from outputs of a controller PCB to loads, or it may be a functional diagram.

The descriptions of the machine are subject to change for product improvement, and major

changes will be communicated in the form of Service Information bulletins.

All service persons are expected to be fully familiar with the contents of this Service Manual and Service Information bulletins to develop a good understanding of the machine, equipping themselves with the ability and skill to identify faults and to maintain the machine in good order.

CHAPTER 2 OPERATIONS AND TIMING

1.2 Outline of the Electrical Circuitry

The finisher’s sequence of operation is controlled by the finisher controller PCB. It is a

32-bit CPU, and is designed to communicate with its host.

The CPU on the finisher controller PCB contains a flash ROM used to store the operating

sequence program.

The finisher controller PCB uses the serial communication line to receive various commands from its host to drive the motors. It also uses serial communications to send information on the sensors and switches to its host.
