and

onto

the

bearing

plate

(see

Figure

Two

parameters

control

the

position

of

text

and

graphics

on

the

label.

By

changing

the

value

of

each

parameter,

the

location

of

the

text

or

graphics

printed

on

the

label

can

be

adjusted.

•

The

of

the

printed

image,

moving

the

position

of

characters

or

graphics

from

the

top

to

bottom

of

the

(Y

axis).

See

Figure

The

value

defines

how

far

a

label

is

extended

above

the

application

plate

just

before

it

is

applied

to

a

(see

Figure

by

pressing

LOWER

CASE

W.

Increasing

the

numeric

advances

the

label

farther

above

the

application

plate.

When

the

thermal

printer

is

operating

correctly,

the

label

and

ribbon

material

advance

smoothly

and

without

any

binding

or

excess

slack.

If

any

of

the

clutches

that

are

attached

to

the

rollers

begin

to

bind,

they

can

cause

the

feeding

and

advancing

of

both

label

and

ribbon

material

to

go

out

of

adjustment.

To

adjust

the

thermal

printer,

follow

these

steps

(see

Figure

5-9):

1.

Starting

with

the

ribbon

(supply)

roll

hub,

check

that

it

has

only

slight

friction.

Remove

the

ribbon

hub

and

spring

washer.

2.

Hold

the

spring

washer

in

your

hand

and,

using

small

needlenose

pliers,

bend

the

three

fingers

so

they

produce

less

(or

more,

if

required)

friction

on

the

hub.

3.

Reinstall

the

spring

washer

and

hub

on

the

printer.

Check

that

there

is

now

only

slight

friction.

4.

Print

a

label

and

observe

the

amount

of

slack

in

the

ribbon

when

the

printer

head

pivots

up

to

print.

The

ribbon

should

droop

down

about

3/4”

when

the

print

head

pivots

up.

If

it

does

not,

loosen

the

lock

nut

on

the

damper

at

the

top

of

the

air

cylinder

using

small

needlenose

pliers,

and

adjust

it

counterclockwise

with

a

small

flat-

blade

screwdriver

until

the

head

pivots

up

fast

enough

to

create

the

droop.

Then

tighten

the

lock

nut

with

the

small

needlenose

pliers.

If

necessary,

remove

the

two

screws

that

hold

the

guard

in

place.

Loosen

the

collar

and

remove

the

ribbon

drive

roller

assembly

from

the

printer.

Hold

the

roller

with

one

hand

and

turn

it

with

the

other.

If

more

than

a

small

amount

of

friction

is

felt,

adjust

the

collar

counterclockwise

until

only

a

slight

amount

of

friction

is

felt.

Note:

If

the

ribbon

drive

roller

assembly

has

a

Belleville

washer

rather

than

a

finger

spring

washer

(Part

Number

265-4485-901),

让

should

be

replaced

with

the

finger

spring

washer,

fingers

out,

fb〃owed

by

the

washer,

and

finally

the

collar,

which

allows

for

a

greater

range

of

adjustment.

6.

Install

the

adjusted

ribbon

drive

roller

assembly

by

sliding

the

complete

assembly

onto

the

shaft.

Hold

the

assembly

in

place

with

your

index

finger

on

the

center

of

the

drive

pulley

and

thumb

on

the

ribbon

drive

roller,

and

tighten

the

collar

with

the

assembly

held

in.

You

might

have

to

hold

the

back

side

of

the

clutch

so

the

shaft

does

not

slide

back.

Note:

The

collar

tightens

most

easily

and

securely

when

the

slots

on

the

collar

are

aligned

with

the

slots

on

the

ribbon

drive

roller.

7.

Install

the

guard

and

check

to

make

sure

the

ribbon

drive

roller

is

not

dragging

against

the

guard.

If

the

roller

contacts

the

guard,

shim

the

guard

out

slightly

using

one

or

more

flat

washers.

8.

Check

the

take-up

roller.

It

should

have

only

slight

friction.

Then

adjust

the

clutch

on

the

shaft

on

the

inside

of

the

printer,

if

needed.

9.

To

check

the

adjustment,

run

PRINT

ONLY

mode

and

make

sure

all

of

the

following

are

true:

•

Print

quality

is

good

(crisp,

clear,

legible,

and

properly

aligned).

•

Ribbon

does

not

get

caught

in

the

application

area.

•

Ribbon

takes

up

properly.

•

Ribbon

does

not

move

during

calibration.
