8. Thread the label liner across the platen and lower the application

plate to hold it in position.

9. Route the liner to the left side of roller

and to the right of roller

Allow the remaining liner to drape to the left of knob

10. Move roller

to the right until it snaps into position.

Note: To ensure correct label printing and application, make sure both pinch

rollers (

and

) are fully engaged.

Calibrating Labels

At certain times, you must calibrate the labels so that the 2500 can

correctly print and apply them to devices. During the label calibration

process, the ADC (label detection) optic reads and assigns a value to the

amount of light passing through the label when it is blocking the optic.

You can view and adjust this ADC optic value from the 2500’s optics

diagnostics menu (refer to page 5-34).

You must calibrate labels whenever you:

• Change the labels

• Change the ribbon

• Advance the labels by running the label drive motor test, turning the

label advance knob, or pulling the labels forward by hand

• Adjust the ADC optic value

To calibrate labels, do the following:

1. Place your finger next to the press bearings to “catch” the two or

three labels that are advanced during the calibration process.

2. Press

CAL

on the 2500’s keyboard.

3. When the labels stop advancing, calibration is complete.

Installing the Dot Matrix

Printer Ribbon Cassette

Install the labeler ribbon cassette in the dot matrix printer by following

this procedure (see Figure 2-10):

1. Rotate the knob on the new cassette in the direction indicated by the

arrow (counter-clockwise) to pull the ribbon taut.

2. Guide the new cassette so the ribbon fits between the print head and

the platen.

3. With the ribbon now partially in place over the print head, slowly

turn the cassette knob while applying gentle pressure on the cassette

until it drops into place on the ribbon spline drive. The spline drive is

located on the labeler directly behind the ribbon advance knob.

Note: You will have to turn the ribbon advance knob slightly until the slot on

the back of the cassette aligns with the spline drive.

4. Ensure that the ribbon is in place by lightly pulling on it. It should not

come off the clips.

5. Calibrate the labels (see page 2-10).

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.
