Power
Supplies
Four
power
supply
assemblies
are
located
in
the
body

Dot
Matrix
Label
Printer
The
dot
matrix
label
printer
(also
simply
referred
to
as
labeler)
uses
a
2
x
12-wire,
in-line
dot
matrix
print
head
to
print
labels.
The
labels
are
on
a
roll
of
label
liner
that
is
threaded
through
the
labeler
assembly
from
a
label
supply
reel.
The
labeler
can
print
a
maximum
of
three
lines
of
text
on
a
label.
The
label
drive
motor
is
the
second
motor
mounted
behind
the
labeler
assembly
plate.
It
provides
the
drive
to
turn
two
rollers
that
advance
the
liner
through
the
labeler
system.
The
black
pinch
roller
snaps
into
position
to
assist
the
label
advance
roller
to
get
a
firm
grip
on
the
label
liner.
The
timing
of
the
label
advance
roller
has
to
be
precise
so
it
can
accurately
place
the
label
on
the
device
and
ensure
even
spacing
between
the
printed
characters
on
the
label.
The
2500
lets
you
choose
the
position
of
the
label
on
the
device.
In
order
to
accomplish
this,
the
labeler
must
know
the
location
of
the
labels
on
the
liner
and
must
be
able
to
advance
the
label
so
it
contacts
the
device
at
the
correct
time.
On
the
front
of
the
labeler
assembly
plate,
the
ADC
optic
roller
assembly
detects
the
leading
edge
of
the
label.
The
highly
sensitive
ADC
optic
emitter/collector
pair
reads
the
level
of
light
that
passes
through
the
combined
label
and
liner
during
label
calibration.
This
light
reading,
called
the
ADC
optic
value,
is
the
reference
used
to
compare
to
the
higher
level
of
light
detected
when
only
the
liner
passes
through
the
optic.
This
reading
allows
the
labeler
to
synchronize
to
the
leading
edge
of
the
labels.
Character
Sizes
The
labeler
can
produce
six
font
sizes,
measured
in
characters
per
inch
(CPI).
The
six
font
sizes
are
listed
below.
•
Normal
Fonts:
18,
20,
and
26
CPI
•
Short
Font:
26

•
