For

raplacement

parts,

use

the

genuine

parts

with

their

part

numbers

specified

in

the

parts

manual.

Use

of

a

wrong

part

could

cause

an

overload

or

dielectric

breakdown

resulting

in

an

electric

shock

or

fire.

®

Replace

a

blown

fuse

or

thermal

fuse

with

the

corresponding

genuine

part

with

its

partnumber

specified

in

the

parts

manual.

Use

of

a

fuse

with

a

different

rating

or

one

with

the

same

rating

but

of

a

different

type

can

result

in

a

fire.

Especially

when

a

thermal

fuse

blows

frequently,

the

thermal

control

system

is

probably

faulty.

Be

sure

to

take

necessary

action.

©

Before

attempting

to

disassemble

the

machine,

be

sure

to

unplug

Its

power

cord.

The

machine

contains

a

high

voltage

unit

and

a

circuit

with

a

large

current

capacity

that

may

cause

an

elactric

shock

or

burn

from

sparking.

The

machine

also

contains

quick

moving

parts,

which

could

injure

a

person.

If

the

machine

uses

a

laser,

a

person

can

lose

his/her

eyesight

by

a

laser

beam

leak.

©

Wherever

feasible,

keep

the

covers

and

parts

mounted

when

energizing

the

machine.

If

it

is

absolutely

necessary

to

energize

the

machine

with

its

cover

removed,

do

not

touch

an

exposed

part

that

is

being

charged

and

use

care

not

to

allow

your

clothing

to

be

caught

by

a

timing

belt,

gear,

or

other

moving

part.

©

Do

not

leave

the

machine

unattended

while

it

is

being

energized.

@

To

actuate

an

interlock

switch

with

a

cover

removed

or

opaned,

be

sure

to

use

the

interlock

switch

actu-

ating

Jig.

Use

of

folded

paper

can

damage

the

interlock

switch

mechanism.

@

A

high

voitage

is

being

applied

to

the

part

marked

with

the

symbol!

shown

on

the

right.

Touching

it

can

cause

an

electric

shock.

Be

sure

to

unplug

the

power

cord

when

servicing

this

part

or

other

parts

near

it.

®

When

the

machine

is

energized

with

any

of

its

covers

removed,

never

use

a

flammable

spray

near

it,

as

a

fire

can

result.

©

Make

sure

that

correct

screws

(diameter

and

length

of

the

screw,

binding/tapping

screws)

are

used

in

the

correct

places

when

assembling

parts.

If

a

wrong

screw

Is

used,

a

short

insulating

distance

could

result.

It

could

also

resultin

collapsed

threads,

which

provides

only

a

poor

connection,

result-

ing

In

and

spring

washer,

If

used

originally,

must

be

reinstalled.

If

they

are

left

out,

acontact

failure

results,

causing

an

electric

shock

or

fire.

Replace

a

lithium

cell

only

with

one

having

the

part

number

specified

In

the

parts

manual.

An

explosion

could

result

if

the

call

is

installed

with

wrong

polarity

or

a

wrong

cell

is

installed.

Dispose

of

a

used

lithium

cell

according

to

the

applicable

local

regulations.

Never

throw

it

away

or

aban-

don

it

on

the

user’s

premises.

@

Other

Precautions

@

While

the

machine

is

being

energized,

do

not

unplug

or

plug

in

a

connector

on

a

PWB

or

relay

harness.

®@

Since

the

Magnet

Roller

of

the

Imaging

Unit

generates

a

strong

magnetic

force,

do

not

bring

a

CRT,

watch,

floppy

disk,

or

magnetic

card

near

it.

°

Use

of

an

air

gun

or

vacuum

generates

static

electricity

which

can

cause

the

ATDC

Sensor

and

associated

-

parts

to

break

down.

Be

sure

therefore

to

use

a

blower

brush

or

cloth

to

clean

these

parts.

If

a

unit

is

to

be

cleaned,

be

sure

to

remove

the

sensors

in

advance,

®

MOS

ICs

are

susceptible

to

static

electricity.

When

handling

a

PWB

loaded

with

MOS

ICs,

follow

precau-

i

tions

given

in

“INSTRUCTIONS

FOR

HANDLING

THE

PWBs

WITH

MOS

ICs.”

°

The

PC

Drumis

highly

delicate.

When

handling

the

PC

Drum,

follow

the

precautions

given

in

“HANDLING

'

OF

THE

PC

DRUM.”

°

To

reassemble,

reverse

the

order

of

disassembly

unless

otherwise

specified.

®

Note

that

replacement

of

a

PWB

may

call

for

readjustments

or

The

following

precautions

must

be

observed

when

handling

Boards

with

MOS

(Metal

Oxide

Semiconductor)

ICs.

During

Transportation/Storage:

@

During

transportation

or

when

in

storage,

new

P.W.

Boards

must

not

be

indiscriminately

removed

from

their

protective

conductive

bags.

@

Do

not

store

or

place

P.W.

Boards

in

a

location

exposed

to

direct

sunlight.

@

When

it

becomes

absolutely

necessary

to

remove

a

Board

from

its

conductive

bag

or

case,

always

place

it

on

its

conductive

mat

in

an

area

as

free

as

possible

from

static

electricity.

@

Do

not

touch

the

pins

of

2.

Gently

wipe

the

residual

toner

off

the

surface

of

the

PC

Drum

with

a

dry,

Dust-Free

Cotton

Pad.

a)

Rotate
