Adjusting

Dot

Matrix

Print

Head

Gap

The

print

head

gap

is

set

at

the

factory

and

will

not

usually

need

to

be

changed.

If

there

are

substantial

changes

in

the

thickness

of

the

label

or

label

backing,

however,

you

may

need

to

make

an

adjustment.

If

the

gap

between

the

platen

and

the

print

head

is

too

wide,

it

may

result

in

slanted

or

fuzzy

printing.

If

the

gap

is

too

narrow,

the

print

ribbon

may

rub

against

the

labels,

smudging

them

and

making

the

background

gray.

CAUTION:

Dangerous

high

voltages

are

present.

Do

not

perform

this

procedure

while

power

is

on

to

the

2500.

This

procedure

should

be

performed

only

by

a

qualified

service

technician.

To

adjust

the

print

head

height,

follow

these

steps:

1.

Turn

off

and

unplug

the

2500.

2.

Remove

the

ribbon

cartridge

and

labels.

3.

Locate

the

two

corner

screws

on

the

main

plate

that

hold

the

plate

in

position.

Loosen

these

screws

so

the

plate

is

free.

4.

Lift

the

main

plate

so

you

can

see

inside

the

2500's

base.

5.

Locate

the

four

hex

screws

on

the

back

side

of

the

print

head

that

hold

it

in

position.

Loosen

the

screws,

but

do

not

remove

them.

6.

When

the

print

head

is

free

to

move,

move

it

as

far

to

the

right

as

possible,

then

adjust

the

gap

between

the

print

head

and

the

underside

of

the

platen

to

approximately

0.018

inches.

7.

Hold

the

print

head

in

this

position

and

tighten

the

four

hex

screws.
