UNWIND BRAKE ADJUSTMENT
The
following
procedure
should
only
be
performed
by
a
Qualified
Service
Technician.
Place
the
machine
offline
before
you
perform
the
following
procedures
or
you
may
be
injured
by
the
moving
unwind
disk
or
dancer
arm.
Figure

Unwind
Brake
configuration
Figure
13
shows
the
standard
spring
and
strap
arrangement.
If
the
strap
is
too
loose,
the
brake
will
not
stop
the
unwind
mandrel.
If
the
strap
is
too
tight,
the
printer's
stepper
motor
must
pull
against
the
unwind
brake
especially
near
the
end
of
a
roll
of
labels.
Use
the
instructions
below
to
adjust
the
tension
of
the
strap.
The
dancer
arm
and
unwind
brake
are
of
little
use
if
the
label
core
spins
on
the
unwind
hubs.
If
the
label
core
slips
on
the
unwind
hubs,
apply
several
labels
to
the
inside
of
the
label
core
to
decrease
the
inside
diameter
of
the
label
core.
Apply
as
many
labels
to
the
inside
of
the
label
core
as
needed
to
provide
a
snug,
nonslip
ping
fit
onto
the
unwind
hubs.
