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.

Loading Labels in the

Thermal Printer

Threading labels on the thermal printer/labeler is similar to threading

labels on the dot matrix printer/labeler (see Figure 4-16). The major

differences on the thermal printer/labeler are:

• The ADC label optic is stationary.

• 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 the procedure below to load a new roll of labels into the thermal

printer.

WARNING:A hinged cover protects operators from injury while the

labeler is operating. Be sure that this cover is in place over

the labeler before you start a printing or labeling

operation.

1. Lower the labeler cover.

2. Push the label pinch roller and the platen pinch rollers into their

retracted positions away from the platen.

3. Remove the magnetic cover from the label roll.

4. 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 4-16).

5. Replace the magnetic cover over the label roll to hold the labels in

place.

6. Prepare the label path by raising the application plate and retracting

the platen pinch and label pinch rollers.

7. 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.

8. 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.

9. Thread the liner between the ADC optic and the platen, and then

between the print head and the platen.

10. Make certain that the label liner is flat against the underside of the

platen.

11. Feed the liner back over the top of the platen and through the gap

between the platen and the track.

12. Thread it between the label drive roller and the label pinch roller (see

Figure 4-16).

13. 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.

14. Lower the label application plate.

15. Lift the labeler cover back into its operating position.

This completes the installation procedure. Be sure to calibrate the labels

as described in the next section before attempting to label devices.

Calibrating Labels in the

Thermal Printer

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

labels after you have finished either one 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 Devices in

the Input Track

The orientation of devices in the input track is critical.

The 2500 uses the

location of pin 1 (as specified in the Task you are running) to determine

how to rotate the beam so that it correctly inserts the device in the

programming module’s block. Because the way you insert devices in the

input track is already defined as part of the Task, you must know your

company’s standards and be careful to insert each tube of devices to

match that standard.

In most cases, the default orientation defined by TaskLink is used. At the

start of a Task, TaskLink displays a drawing with the position that the

Task has defined for pin 1 (see Figure 4-21). Install devices upside-down

so that their leads point toward the ceiling (see Figure 4-17).

The default positions for pin 1 are:

• DIP and SOIC devices: Pin 1 is to the right, closest to the input tube.

• 32-pin PLCC devices: Pin 1 is to the right, closest to the input tube.

• Square PLCC devices: Pin 1 is pointing to the back of the 2500.

CAUTION: Insert all input tubes with the device leads pointing up

toward the ceiling. Insert square PLCC devices with pin 1

oriented toward the back of the 2500, away from you. Insert

rectangular PLCC (32-pin), DIP and SOIC devices so that

pin 1 is oriented to the right. Failure to insert devices so they

match the Task configuration may damage both the device

and the programming module.

To insert a tube according to these defaults, hold the tube so you can see

the top of the devices and the pin 1 indicator (see Figure 4-17). Turn the

tube upside-down (rotate it 180 degrees) and insert the tube in the input

tube holder.
