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.

Calibrating Labels

The label optic must be calibrated to detect and synchronize with the

labels after you have finished any of the following operations:

• Installing a new roll of labels

• Changing the ribbon

• Adjusting the ADC reference value

• Manually moving the labels

Perform the following steps to calibrate the labels.

1. Put your finger near the label application point (the right edge of the

application plate).

2. Press

CAL

on the front panel of the 2500.

3. Use your finger to catch the three or four labels ejected while the

labels are being calibrated.

Installing a New Ribbon

Each new ribbon roll has a long leader to thread through the labeler.

Follow the procedure below to install the new ribbon (refer to Figure

2-12).

1. Prepare the ribbon threading path by pushing the ribbon pinch roller

to the right.

2. Install the ribbon take-up core (one empty core is supplied with the

printer) on the ribbon take-up hub. After threading the ribbon, you

will tape the ribbon’s leader to this cardboard core.

3. Thread the ribbon leader over ribbon alignment roller 1, over the

print head, and over ribbon alignment roller 2.

4. Thread the ribbon leader under the ribbon drive roller, over the

ribbon pinch roller, and down to the ribbon take-up roll (see Figure

2-12).
