The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation.

In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal.

The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power.

2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low". (The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.

In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine.

Pickup delay jam 2In case of pickup from the option cassette 1: When the leading edge of paper is not detected within the specified period of time by the PF Feed Sensor 1 after pickup starts, it is judged as a pickup delay jam 2.In case of pickup from the option cassette 2: When the leading edge of paper is not detected by the PF Feed Sensor 1 of the option cassette 1 after the PF Feed Sensor 2 detects the leading edge of paper, it is judged as a pickup delay jam 2

Pickup delay jam 3When the leading edge of paper is not detected within the specified period of time by the PF Feed Sensor 2 after pickup starts from the option cassette 2, it is judged as a pickup delay jam 3.

INTRODUCTION:

Points to Note During Disassembly and AssemblyBe sure to pay attention to the below points in performing disassembly and assembly.1. In performing disassembly and assembly, for safety precaution be sure to disconnect the

power plug.2. If there is no special instruction, perform the assembling work in the reverse way of

disassembling procedure.3. In the places where screws, etc. are used, be sure not to install them wrongly (length/

diameter).4. To ensure electric conduction, binding screw with washer is used for the mounting screws,

e.g. for earth wire or varistor, etc. Be sure to use this screw in performing assembling-installing.

5. It is a basic rule that machine is not to be operated when parts is in the removed condition. 6. In disassembling, do not remove the paint-locked screw.
