to
check
that
there
are
24
printed
dots.
If
you
suspect
that
one
of
the
wires
is
not
firing,
you
may
check
the
control
circuit
on
the
handler
controller
board
that
drives
each
wire.
Each
circuit
includes
an
LED
that
turns
on
when
the
labeler
wire
is
enabled
by
its
control
circuit.
Refer
to
Figure
5-20
for
the
location
of
these
LEDs.
Each
LED
number
has
a
CR
prefix.
Check
the
LEDs
while
you
are
running
the
print
test
to
confirm
that
all
the
LEDs
are
turned
on.
Disconnect
the
two
print
head
cables
to
determine
whether
that
problem
is
on
the
handler
controller
board,
the
cable,
or
the
print
head.
