Up to three lines of text with 25 characters per line are available, but the

number of lines and characters that will fit on a device is limited by the

size of the device, and type (font). See the charts on pages 5-15 and 5-17.

Three lines is the maximum number currently available. Enter the text

you want on the label. Existing text is overwritten.

To delete a character, move the cursor one space to the right of the

character you want to delete, and press

. To insert a space between

two characters, move the cursor to the right of the place you want to add

a space, and press

SHIFT

and

SPACE

Print Test

(Dot Matrix Printer)

This test activates the 24 print head wires (pins) to verify that they are all

operating. Check the labeler wires by performing the following steps:

1. Press

CAL

to calibrate the labels.

2. With the 2500 in local mode, go to the Diagnostics menu.

3. From the Diagnostics menu, press

to select

PRINT TEST

4. Press and release

START

quickly. The labeler continuously fires all

print head wires (pins) while

START

is pressed. Holding

START

too

long will result in a blurred image on the label and you will not be

able to see the printed points.

5. Press

RESET

to exit the Print Test and return to the Diagnostics

menu.

6. Press

CAL

to calibrate the labels. You should see two clear, parallel

lines printed on the label. Use an eye loupe to check that there are 24

printed dots.

If you suspect that one of the wires is not firing, you may check the

control circuit on the handler controller board that drives each wire. Each

circuit includes an LED that turns on when the labeler wire is enabled by

its control circuit. Refer to Figure 5-20 for the location of these LEDs. Each

LED number has a

prefix.

Check the LEDs while you are running the print test to confirm that all

the LEDs are turned on. Disconnect the two print head cables to

determine whether that problem is on the handler controller board, the

cable, or the print head.
