Test
25
—
Lift

main
plate.
•
VAC
—
Press
V
to
toggle
the
vacuum
generator
on
and
off.
When
the
vacuum
generator
is
on,
place
your
finger
over
the
end
of
the
chuck
to
seal
the
opening
and
the
VAC
value
should
be
greater
than
or
equal
to
140.
You
may
need
to
adjust
the
ADC
optic
if
you
have
trouble
with
label
calibration,
label
position,
or
location
of
printed
text,
especially
if
you
have
just
changed
labels.
To
adjust
the
ADC
value,
select
OPTIC
TEST
from
the
DIAGNOSTIC
MENU
and
load
labels.
Locate
the
ADC
optic
(see
Figure
5-13)
and
ensure
that
a
label
is
blocking
the
optic's
beam
to
ensure
the
maximum
ADC
optic
value.
The
2500
should
display:
If
a
label
is
not
blocking
the
ADC
optic,
slowly
turn
the
label
advance
knob
counterclockwise
to
advance
the
liner.
The
value
on
the
display
fluctuates
until
the
label
blocks
the
optic
and
the
highest
value
appears.
Do
not
begin
the
adjustment
procedure
until
you
are
certain
that
a
label
is
blocking
the
optic.
If
the
ADC
value
does
not
reach
200,
from
the
Optics
diagnostics
menu
press
LOWER
CASE
+
A,
and
then
press
or
until
the
displayed
value
reaches
200.
Turn
the
label
advance
knob
until
the
ADC
optic
reads
only
the
liner.
This
should
read
between
120
to
170
if
the
liner
is
translucent.
The
liner
reading
is
variable,
so
there
is
no
adjustment
for
it.
Return
to
the
Main
Menu
by
pressing
RESET.
Press
CAL
to
have
the
2500
run
a
label
calibration
to
adjust
to
the
new
setting.

During
Calibration
Adjusting
the
ADC
Optic
on
the
Thermal
Printer
The
ADC
optic
detects
the
leading
edge
of
the
label
on
the
liner.
When
using
Auto
ADC),
the
software
calculates
an
ADC
value
and
no
manual
adjustment
is
required
for
variations
in
batches
of
labels.
Auto
ADC
turns
on
the
ADC
optic
and
reads
the
amount
of
light
passing
through
the
label
and
liner
to
establish
a
reference
level
of
light.
When
the
ADC
optic
detects
a
light
level
above
that
reference
value,
the
2500
assumes
that
it
is
detecting
a
gap
between
labels
where
only
the
liner
is
blocking
the
optic's
light
beam.
You
can
manually
check
and
adjust
the
ADC
value
using
the
2500's
Diagnostic
tests.
You
may
need
to
manually
adjust
the
ADC
optic
if
you
have
trouble
with
label
calibration,
label
position
on
the
device,
or
location
of
printed
text
on
the
label.
