PRECAUTIONS BEFORE SERVICING

•

The

printer

mechanism

fixed

the

chassis

with

four

screws

keep

from

being

damaged

vibration,

etc.

during

transport.

Remove

these

screws

when

using, main-

taining

repairing

the

printer.

Fix

the

mechanism

again

with

these

screws

when

transporting

the

printer.

• Do

not

apply

head,

such

touching

when

operating.

•

The

head

becomes

very

hot

not

touch

with

your

hand

until

cools

down

sufficiently.

• Do

not

when

the

ink

ribbon

loose.

• When servicing

and

checking

printer

that

has

been

used

for

a long

time,

remove

dirt,

fuzz

and

dust

from

th~

inside,

and

oil

the

•

There

are

two

types

oil,

and

Use

the

proper

oil

for

each

oil

point.

(Refer

page

63,

for

oil

points.)

•

There

are

screws

and

nuts

which

are

fixed

and

then

locked

with

paint

for

vibration-

proof

etc.

during

transport.

Paint

the

Logics

and Drivers

1. Block diagram

The

printer

employs

two

microprocessors,

8085

and 8039. The

former

primarily

used

for

data process and

head

control,

and the

latter

for

stepping

motor

control

and

control

switch

input

process. Employed external

ROM's

are

2732

and 2716. The

former

stores processing programs and condensed characters

for

the micro-

processor 8085, and the

latter

processing programs

for

8039.
