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

REF.

Indicates an item of reference assisting the understanding of the topic in question.

Provides a description of a service mode.

Provides a description of the nature of an error indication.

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 fi eld. Ther efore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of fro m 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."

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 MF4300dn / i-SENSYS MF4350d / i-SENSYS MF4380dn / i-SENSYS MF4310/4318 / i-SENSYS MF4320d / i-SENSYS MF4330d / i-SENSYS MF4340d / i-SENSYS D450d / i-SENSYS MF4370dn

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.

When performing servicing work around the laser scanner unit of this machine, be sure not to insert a highly reflective tool such as a driver directly into the laser light path. Also be sure to take off a watch or ring, etc. during servicing work. (Otherwise, the reflected laser beam may enter the eye.) The color of the laser light for this machine is red. The labels [1] and [2] shown in the figure below are attached on the covers where the laser light may be reflected. Further, no adjustment can be made to the laser scanner unit of this machine in the field. The label [1] shown in the figure below is attached on the cover of the laser scanner assembly.

1.1.2.4 Safety of the Toner

i-SENSYS MF4300dn / i-SENSYS MF4350d / i-SENSYS MF4380dn / i-SENSYS MF4310/4318 / i-SENSYS MF4320d / i-SENSYS MF4330d / i-SENSYS MF4340d / i-SENSYS D450d / i-SENSYS MF4370dn

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

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

How to handle the toner adhered

1. When toner is adhered to the skin or clothing, wipe it off the skin or clothing by a dry tissue and wash the skin or clothing with water.

2. If you use hot water, toner is turned into gel and soaks into clothing. Under such a condition, toner cannot be removed.

3. Do not make toner come into contact with a vinyl material because they tend to react with each other.

1.1.2.5 Fire Attention

i-SENSYS MF4300dn / i-SENSYS MF4350d / i-SENSYS MF4380dn / i-SENSYS MF4310/4318 / i-SENSYS MF4320d / i-SENSYS MF4330d / i-SENSYS MF4340d / i-SENSYS D450d / i-SENSYS MF4370dn

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 MF4300dn / i-SENSYS MF4350d / i-SENSYS MF4380dn / i-SENSYS MF4310/4318 / i-SENSYS MF4320d / i-SENSYS MF4330d / i-SENSYS

The operations of this host machine are controlled by CPUs of the SCNT PCB within the Reader Controller System and the DCNT PCB within the Engine Control System. The table below shows the purpose of each interval and the outline of the operations of reader unit and the engine from turnon of the power supply to stop of each motor after printing.

T-2-1

interval name definition of interval purpose remarks

WAIT (wait) Interval between turnon of the

STBY (standby) Interval between the end of WAIT

INTR (initial rotation) Interval between the input of print

PRINT (print) Interval between the end of initial

LSTR (last rotation) Interval between turnoff of the

power supply and the end of the initial drive

or LSTR and input of print command from SCNT PCB, or interval between the end of LSTR and turnoff of power supply

command from SCNT PCB and turnon of the Cassette pickup solenoid

rotation and turnoff of the primary high-voltage output

primary high-voltage output and stop of the main motor

To clear the drum surface potential and to execute the cleaning of transfer charging roller

To make the host machine ready for printing

To stabilize the photosensitive drum as a preparation for printing Also to clean the transfer charging roller

To form an image onto the photosensitive drum based on the video signal input from the SCNT PCB and to transfer the toner image onto media

To fully deliver the final sheet printed Also to clean the transfer charging roller

Presence/absence of cartridge is detected during this interval.

On input of print command from the SCNT PCB, host machine enters INTR immediately after LSTR. However, depending on the conditions shown below, the host machine may not start INTR immediately.
