Loading Labels

The 2500 labeler prints using either a 24-wire in-line dot matrix printer or

a thermal printer. Labels usually need to be changed each time a new

device package type or different pin count is required by the Task you are

going to run. Labels are positioned on a non-adhesive liner material so

they will peel easily as they advance around the label platen’s point. The

label part number and date code are written on a label attached to the

inside of the label roll.

Note: The label part number is marked on the inner cardboard reel. You can

identify a roll of ProMaster 2500 labels by the “QF” prefix in the part

number. Labels for other Data I/O products will look the same but cannot

be used on the 2500.

The 2500 allows you to adjust where the label is applied on the device.

This parameter, called label placement, will usually be changed by the

system administrator. To place the label, the 2500’s labeler must know

where the labels are on the liner and must be able to advance the liner so

the label contacts the device at the correct time. The label detection optic

assembly (known as the ADC optic) detects the leading edge of the label

so the label drive motor can position it for correct application to the

device.

If you are switching between Kapton™ and polyester labels, check the

ADC optic value (see page 5-34) and adjust it as required so that it reads

200

when reading the label on the liner. The ADC value changes slightly

for these two label material types.

Follow the instructions in the following sections for threading the new

label stock through the appropriate printer type’s assembly.

Loading Labels in the Dot

Matrix Printer

Rollers and other components of the labeler are referred to by letters in

this section to make the threading instructions easier to follow.

Refer to Figure 4-15 andthefollowingproceduretoinstallarolloflabels.

1. Raise the application plate and slide rollers

and

in the direction

shown by the arrows in Figure 4-15. This prepares the path of the

labels to be threaded through the labeler.

2. On a standard reel, the label release knob is attached to a core pin that

holds the label roll in place. Loosen the label release knob just enough

to move it toward the center of the reel (so that the core pin no longer

protrudes), and lock the knob in this retracted position.

For a magnetic supply reel, remove the plate.

3. If labels are already installed, unthread the liner, and remove the old

label roll by putting your thumbs in the cut-outs in the supply reel

and rocking the roll back and forth as you pull it off.

4. Install the labels on the supply reel so that the label liner passes to the

left of optic

(see Figure 4-15).

5. If the 2500 uses a standard reel, loosen the release knob and push the

pin into the cardboard core of the label roll. Tighten the knob to hold

the pin in place against the roll’s cardboard roll.

If the 2500 uses a magnetic supply reel, reinstall the plate.

6. Unroll approximately two feet of liner. Thread it around the left of

roller

, between

and

, and between the platen and press

bearings.

7. Move roller

to the left so it pinches the label liner and holds it in

position. Ensure that the labels are fully aligned between the

underside of the platen and above

and

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

Drape the remaining liner to the left of the label advance 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 in the

Dot Matrix Printer

The ADC (label detection) optic must be calibrated at certain times so that

labels can be correctly applied to the devices. You must calibrate this

optic whenever you:

• Change labels or the ribbon.

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

label advance knob, or pulling the labels forward by hand.

• Change the ADC optic value (described on page 5-34).

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.
