Introduction

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, theoperations of the microprocessors used in the machines are not discussed: they are explained in terms of fromsensors 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 otherpurposes, 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 relevantService Information bulletins and be able to identify and isolate faults in the machine."

2.2 Pick-Up/Feed Systm

2.2.1 Overview 0001-9309

The paper inside the cassette is held up by the work of the lifer plate. When pickup takes place, the pickup rollermoves down to come into contact with the stack of paper. The pickup roller starts to move down when the pickupsolenoid goes on. The feed roller and the separation roller make sure that no more than a single sheet of paper ismoved forward to the paper path. The vertical path roller serves to move paper as far as the registration roller.The pickup path roller, pickup roller, feed roller, and separation roller are driven by the pickup motor.

2.2.3 Identifying the Paper Size 0001-9314

The size of paper inside the cassette is detected by the cassette size dial, and is communicated to the cassette sizedetection PCB.As may as 15 positions may be detected with reference to the combinations of on and off states of the array of 4actuators mounted to the cassette size detection PCB on the printer side and operating in conjunction with the cassettesize dial.In the absence of a cassette, all 4 actuators are off, causing the machine to assume there is no cassette.AB/Inch SwitchThe cassette size dial is equipped with a switch operated to change between AB and Inch configurations; the cassettesize detecting switch will detect the configuration as soon as a cassette is fitted in the machine.

2.2.4 Paper Level Sensors 0001-9316

The following sensors are used to check the level of paper found inside the cassette:

SW4 is used to detect the state of the AB/Inch-configuration switch.The machine will assume the absence of a cassette if it detects a combination not found in the table. At this time, it does not move up the cassette lifter.Since the paper size is not identified, there will be no indication of a paper size on the control panel; when the cassette in question is selected, the machine will indicate a message prompting the supply of paper.

Points to Note 1 When Replacing the Feed/Separation Roller

The collar (roller core) of the machines feed/separation roller is black. Do not mount a feed/separation roller designed (mint green) for adifferent model; otherwise, ingredients of the rollercan start to build up on the intermediate transferbelt, causing transfer faults.


The collar (roller core) of the machine's separation/feed roller available as a service part is black.

At times, however, you may find that a separation/feed roller with a gray collar (roller core) used inthe machine; if so, be sure to use a roller with ablack collar (roller core) when you must replace itwith a service part.
