ADJUSTING THE PRINT QUALITY

One

of

the

nice

features

of

the

SATO

“Se”

printers

are

their

high

print

quality.

They

are

equipped

with

two

different

methods

of

adjusting the

quality

of

the

print:

print

darkness

and

speed.

When

adjusting

for

optimum

print

quality,

a

bar

code

verifier

system

should

be

used.

The

human

eye

is

a

poor

judge

of

the

relative

widths

of

the

bars

in

a

symbol,

a

characteristic

that

is

extremely

important

for

good

)

This

adjustment

allows the

user

to

control

(within

a

specified

range)

the amount

of

power

that

is

used

to

activate

the

individual

print

head

heat

elements.

It

is

important

to

find

a

proper

print

darkness

level

based

on

your

particular

label

and

ribbon

combination.

The

printed

images

should

not

be

too

light

nor

should

the

ink

from

the

ribbon

“bleed.”

The

ed

g

es

of

each

ima

g

e

should

be

cris

p

and

well

defined.

The

Print

Darkness

can

be

set

using

the

front

panel

LCD

panel

or

by

downloading

the

setting

using

the

Print

Darkeness

software

command.

Once

the

range

has

beenselected,

the

PRINT

Potentiometer

on

the

front

panel

can

be

used

to

make

finer

j

ustments.
