Introduction

Symbols Used

This documentation uses the following symbols to indicate special information:

Symbol Description

Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.

Indicates an item requiring care to avoid electric shocks.

Indicates an item requiring care to avoid combustion (fire).

Indicates an item prohibiting disassembly to avoid electric shocks or problems.

Indicates an item requiring disconnection of the power plug from the electric outlet.

Indicates an item intended to provide notes assisting the understanding of the topic in question.

Memo

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, 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."

1.1.2 Safety

1.1.2.1 Safety of the Host Machine's Laser Mechanism i-SENSYS MF4150 / i-SENSYS MF4140 / i-SENSYS MF4120 /

Laser radiation can prove to be harmful to the human body. The host machine's laser scanning system is completely sealed by means of a protective housing and external covers so that its light will not leak outside the host machine as long as the host machine is used normally.

1.1.2.2 CDRH Regulations

i-SENSYS MF4150 / i-SENSYS MF4140 / i-SENSYS MF4120 /

The Center for Devices and Radiological Health (CDRH) of the US Food and Drug Administrator put into forth regulations that relate to laser products on August 2nd, 1976.

These regulations apply to laser products produced on and after August 1st, 1976, and prohibit the sale of laser products without certification. The following labels certify compliance with the CDRH regulations, and must be attached to all laser products that are sold in the US.

1.1.2.3 Handling of the Laser Assembly

i-SENSYS MF4150 / i-SENSYS MF4140 / i-SENSYS MF4120 /

Invisible laser beam is radiated within the laser scanner unit. Laser beam radiation may pose damage to eyes. Be sure not to disassemble the laser scanner unit. The host machine's laser scanner unit cannot be adjusted in the field. The label [1] shown in the figure below is attached onto the cover of the laser scanner unit.

1.1.2.4 Safety of the Toner

i-SENSYS MF4150 / i-SENSYS MF4140 / i-SENSYS MF4120 /

Toner in General

Toner is a non-toxic material made up of plastic, iron, and small amounts of dye.

Do not throw toner into fire. Doing so can lead to explosion.

Contact with Toner

1.Toner on the skin or clothes must be removed by washing with water immediately.

2.The use of warm water must be avoided, doing so will cause the toner to turn gel-like and to permanently fuse with the fibers of the clothes.

3.Contact with vinyl must also be avoided, as toner can readily react.

1.1.2.5 Fire Attention

i-SENSYS MF4150 / i-SENSYS MF4140 / i-SENSYS MF4120 /

It is dangerous to throw the parts that include combustible materials such as lithium battery and toner cartridge etc., into fire. Any used battery must always be disposed according to the appropriate local regulations.

1.1.2.6 Points no Note when Replacing / Disposing the Lithium Battery i-SENSYS MF4150 / i-SENSYS MF4140 / i-SENSYS MF4120 /

Replacing to wrong type of battery may cause explosion.

Dispose used battery according to the instruction manual.
