Explanation of Symbols

The following symbols are used throughout this Service Manual.

Symbols Explanation

Used to show permission.

Used to show prohibition.

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.

Characteristics

● High-Speed Color Printer

This machine is a high-speed color printer, realizing a speed of approximately 30 pages per minute in full-color printing with A4 vertical paper.

● Introducing Intermediate Transfer Method (ITB)

This machine introduced an intermediate transfer method, in which 4-color toner images are transferred into an intermediate transfer belt (ITB) and then simultaneously transferred into a printing sheet. This method enabled to realize stable color printing in various types of paper without receiving impact of paper at the time of primary transfer.

● Automatic Duplex Printing

This machine supports automatic duplex printing as standard function.

Safety Precautions

Laser Safety

Laser beam radiation sometimes causes a danger to human body. To prevent such a danger, the optical laser system used in this machine is hermetically closed by the protection housing and external cover so that a laser beam does not leak to outside. Therefore, a laser beam does not leak out of this machine as long as a user operates the machine in an ordinary manner.

CDRH Regulation

CDRH (Center for Devices and Radiological Health), which belongs to Food and Drug Administration in USA, put a regulation concerning laser products on August 2, 1976. This regulation is applied to laser products manufactured on and after August 1, 1976, and sales activities are prohibited in USA without receiving permission under the regulation.

The following figure shows the label indicating that permission has been received under the CDRH regulation, and it is obliged to attach it on all products sold in USA.

Toner Safety

■

Caution :

Be sure not to throw toner into the fire. Doing so may cause an explosion.

■ How to Handle Adhered Toner

•When toner adhered to skin or clothes, completely remove it with dried tissue and wash with water.

•If hot water is used, toner cannot be removed because it becomes gel and penetrates into clothes permanently.

•Do not make toner come into contact with vinyl because it easily reacts with a vinyl material.

How to Handle the Laser Scanner Unit

An invisible laser beam is irradiated in the laser scanner unit.

If the laser beam enters an eye, it may cause damage to the eye. So, be sure not to disassemble the laser scanner unit. No adjustment can be made to the laser scanner unit in

this machine in the field.

Points to Note when Replacing/Discarding a Lithium

Battery

Caution :

If the battery is replaced with an incorrect type of battery, it may cause an explosion.

Discard a used battery according to the instruction manual.

Points to Note when Performing Disassembly/Assembly

Be sure to follow the instruction shown below when performing disassembly/assembly.

1.Be sure to unplug the power plug for safety when performing disassembly/assembly.

2.If not otherwise specified, perform assembly in the procedure opposite to that of disassembly.

3.Perform assembly using correct types of screws, etc. (length/diameter) at correct positions.

4.A washer screw is used as a screw to fix a grounding wire and varistor, etc., to secure electrical conduction. Be sure to use this screw when performing assembly.

5.In principle, do not operate the machine in the condition where parts are removed.

6.Do not remove a paint-locked screw when performing disassembly.

Laser Exposure System

Overview

The laser exposure system forms a latent image on the photosensitive drum according to the video signal sent from the main controller.

The laser scanner unit consists of the laser unit and the scanner motor unit. Each unit is controlled by the signal entered from the DC controller.

Two laser scanner units are used in this machine. One is a unit for Y/M, and the other is for C/Bk, which are common units.

One laser scanner unit consists of the laser drive unit, which controls the laser unit, and the scanner motor unit, which controls the scanner motor. One scanner motor and scanner mirror reflect laser beams for two colors.

These parts are contained in the laser scanner unit and controlled by the DC controller. The DC controller irradiates each laser beam according to the video signal received from the main controller. The laser beam falls on the scanner mirror rotating at constant speed. The laser beam reflected from the scanner mirror is irradiated on the photosensitive drum.

Detecting a Failure in the Optical Assembly

When the laser scanner is placed in the following condition, the DC controller judges that a failure occurred in the laser scanner unit and reports it to the main controller.

•Laser failure

When the laser is turned on for a specified time at startup of the laser scanner unit, either of the two laser beams does not reach the specified laser intensity.

•Scanner motor startup failure

Even when a specified time elapses after startup of the laser scanner unit, the number of rotations of the scanner motor does not reach a specified number of times.

•Scanner motor rotation failure

When a specified BD interval cannot be detected during printing, it is judged that a BD error occurred. When the BD interval cannot recover from the fault even after a specified time elapsed after it was judged that a BD error occurred, it is considered that a scanner motor rotation failure occurred.

Safety

The laser scanner unit of this machine does not have a mechanical laser shutter.

To secure safety, two interlock switches for +5VC are mounted. When the front door or right door is opened, the interlock switch works and blocks power distribution to the laser scanner unit.
