!IMPORTANT SAFETY NOTICES

PREVENTION OF PHYSICAL INJURY

1.Before disassembling or assembling parts of the copier and peripherals, make sure that the copier power cord is unplugged.

2.The wall outlet should be near the copier and easily accessible.

3.Note that some components of the copier and the paper tray unit are supplied with electrical voltage even if the main power switch is turned off.

4.If any adjustment or operation check has to be made with exterior covers off or open while the main switch is turned on, keep hands away from electrified or mechanically driven components.

5.If the Start key is pressed before the copier completes the warm-up period (the Start key starts blinking red and green alternatively), keep hands away from the mechanical and the electrical components as the copier starts making copies as soon as the warm-up period is completed.

6.The inside and the metal parts of the fusing unit become extremely hot while the copier is operating. Be careful to avoid touching those components with your bare hands.

HEALTH SAFETY CONDITIONS

1.Never operate the copier without the ozone filters installed.

2.Always replace the ozone filters with the specified ones at the specified intervals.

3.Toner and developer are non-toxic, but if you get either of them in your eyes by accident, it may cause temporary eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1.The copier and its peripherals must be installed and maintained by a customer service representative who has completed the training course on those models.

2.The NVRAM on the system control board has a lithium battery which can explode if replaced incorrectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance with local regulations.

1

1.SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an open flame.

2.Dispose of used toner, developer, and organic photoconductors in accordance with local regulations. (These are non-toxic supplies.)

3.Dispose of replaced parts in accordance with local regulations.

4.When keeping used lithium batteries in order to dispose of them later, do not put more than 100 batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical reactions and heat build-up.

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical units in the field. The optical housing unit can only be repaired in a factory or at a location with the requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore directed to return all chassis and laser subsystems to the factory or service depot when replacement of the optical subsystem is required.

!WARNING

Use of controls, or adjustment, or performance of procedures other than those specified in this manual may result in hazardous radiation exposure.

!WARNING

WARNING: Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser beams can seriously damage your eyes.

The CCD is changed to 4-channel type because

 

 

 

of a higher processing speed. (A229: 2 channels)

 

 

 

A reflector is added to 1st scanner.

 

 

 

The Scanner Motor has been changed to a DC

Overview

The LD unit and Polygon Motor have been

Cleaning Brush

The turning direction of the brush has been

changed to the counter direction to increase the

 

 

 

cleaning ability.

 

 

 

The brush has been changed from a rope type to

 

 

 

a straight type. A rope type scrapes off the drum

 

 

 

surface too much because of the change of the

Paper size setting

The paper size setting can be done at the front side

By-pass Tray

The By-pass Tray Switch has been deleted. The by-

Inverter Exit

The Inverter Exit Clutch has been added to stop a

BICU Board

Scanner control circuit has been independent

N/A

Compo-

 

from SBICU as MCU (Motor Control Unit) and

 

nents

 

Scanner Motor Drive Board is deleted.

 

 

 

The name of SBICU is changed to BICU.

 

 

 

This is because the Scanner Motor has been

 

 

 

changed from a stepper motor to a servomotor to

 

 

 

enable the copying speed in the ADF 1 to 1 mode

 

 

 

to be 70 cpm.

 

 

 

The exposure lamp, APS sensor and scanner HP

 

 

 

sensor are also connected to the MCU.

 

 

I/O Board

The RDS function has been independent from

N/A

 

 

the I/O board as RDS Board and has been

 

 

 

controlled by the BICU board because of the

 

 

 

following reasons:

 

 

 

1. The I/O board can completely turn off in the

 

 

 

weekly timer off mode.

 

 

 

2. It has been possible that only the RDS board is

 

 

 

replaced.

 

 

PSU

A 38V output has been added for the scanner motor

N/A

 

 

that is changed from a stepper motor to a servo-

 

 

 

motor.

 

 

CNB

This is a new name of the Interface Board

N/A

 

(Connector

by-pass motor and development motor are

Those functions are on the DRB (Driver Board) as a

 

 

 

new board.

 

 

 

This is to reduce the harnesses used.

 

 

12V Power

The DC/DC converter has been deleted and its

N/A

function has moved to the PSU.

 

 

DRB

This is an interface board for the signal lines of

The power line for each motor is connected to the

Copy Connect

The connection between the BICU and Copy

N/A
