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
5
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
CR
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.
