2-14 9845B/C Environmental, Installation, and Preventive Maintenance Requirements
The average
life
of the internal thermal printhead
is
about 50,000 feet of paper, or about
250
rolls.
Note
If
you
want
to
use
Metric
paper
in
the thermal printer, the
Metric
Paper Spacer (PIN 5040-8145)
must
be
installed
in
the
paper
hol-
der,
on
the right-hand
side.
Two keys are used to control the printer paper. The PAPER
ADVANCE
key advances the paper
until the key
is
released. The TOP OF
FORM
key advances the paper past perforations to the
top margin (approximately 1.25 cm, or
1f2
inch, below the perforations). If the paper
is
not
perforated,
it
is
advanced
30.5
cm (12 inches).
Printer
paper
is
loaded using the following procedure.
• Make sure the computer
is
switched
ON.
•
Lift
or
remove the access cover on the top of the printer by pushing down on the raised
surface at the rear of the door. The door can be removed by lifting up
and
pulling
it
toward
you.
• Remove
and
discard the paper core of any previous
roll.
If the remaining
roll
of
paper
is
small
and
a new roll
is
to be installed, remove the old
roll.
To do this, first unroll
and
lift
the
old roll upward. Then tear the paper off using the paper guide.
• If any
paper
remains
in
the printer mechanism, remove
it
by pressing the PAPER
AD-
VANCE key until the paper
is
completely out.
• Remove the first layer of paper from the new
roll.
Be sure the paper has a cleanly torn
or
cut edge. Fold the corners
in
to form a point.
• Insert the new roll such that the free
end
is
positioned as shown. Press the PAPER
ADVANCE
key until the paper appears at the front of the printer. Then reinstall the access
door by placing
it
on
the hinge pins
and
pushing until
it
snaps into place.
