Setting Up the
Thermal Printer
Before labels can be printed and applied to processed devices, the label
and ribbon material must first be loaded. The following sections cover
the correct procedures for loading and calibrating labels and loading a
new ribbon and repairing a torn ribbon.
Loading Labels
Threading labels on the thermal labeler is similar to threading labels on
the dot matrix labeler (see Figure 2-11). The major difference on the
thermal printer is that the retractable rollers (platen pinch and label pinch
rollers) snap back into position if you release them. On the dot matrix
labeler, the rollers remain in the open position.
Note: Do not tighten the label roll on its core. The roll is intentionally loose so
the combination of high temperature and humidity do not cause the labels
to peel incorrectly.
Follow this procedure to load a new roll of labels.
1. Push the label pinch roller and the platen pinch rollers into their
retracted positions away from the platen.
2. Remove the magnetic cover from the label roll.
3. Install the new label roll on the label supply hub so that the leader
comes off from the right side of the hub (see Figure 2-11).
4. Mount the magnetic cover over the label roll to hold the labels in
place.
5. Prepare the label path by raising the application plate and retracting
the platen pinch and label pinch rollers.
6. Thread about 2 feet (60 cm) of label liner around the left side of the
label alignment roller and through the gap between the application
plate and the output track. Lay the liner along the output track for the
time being.
7. Position the label liner on the underside of the platen and guide the
platen pinch roller back into its operating position against the platen
to hold the liner in place.
8. Thread the liner between the ADC optic and the platen, and then
between the print head and the platen.
9. Make sure that the label liner is flat against the underside of the
platen.
10. Feed the liner back over the top of the platen and through the gap
between the platen and the track.
11. Thread it between the label drive roller and the label pinch roller (see
Figure 2-11).
12. Thread the liner between it and the drive roller. Guide the spring-
loaded pinch roller back into its operating position against the drive
roller. Make certain that there is no slack in the liner.
13. Lower the label application plate.
This completes the installation procedure. Be sure to calibrate the labels
as described in the next section before attempting to label devices.
