Chuck Is Handling Devices
Incorrectly
The chuck does not work correctly with the devices you are using.
Ensure that you are using the correct chuck size for the devices you are
processing. Refer to the chuck selection chart on page 4-16.
Replace the rubber chuck tip.
Confirm that high and low air pressure gauges are set to the correct
levels.
Make sure there are no air leaks.
Continuity Failures
Try a device-related operation (program or verify) using a device from
another manufacturer to make sure the problem is associated with the
hardware rather than the device or device algorithm.
Carefully check the beam’s alignment to the device and the device’s
alignment to the programming module to verify that the chuck tip is
centered on the device (refer to the device alignment procedure,
beginning on page 4-27).
Run the PE’s self test.
Clean the contacts on the programming module.
CAUTION: This procedure should be performed only by a qualified
service technician.
The contacts may need to be replaced by a service technician.
Devices Are Not Being
Picked Up Correctly
Carefully check the beam’s alignment to the device and the device’s
alignment to the programming module to verify that the chuck tip is
centered on the device (refer to the device alignment procedure,
beginning on page 4-27).
2500 Is Not Operating and
Nothing Is Displayed
The fuse is blown, there is no power, or the power supply is bad.
Check the main fuse (see page 7-2), AC power, power cord connection,
and controller board LEDs. Contact Data I/O Support (phone numbers
listed in the Preface) for specific assistance.
Receiving Tube Overflows
The number of parts per tube is incorrect or the “Device at output tube”
optic is bad. Check optic diagnostic tests 12 and 14.
Tube was removed and reinstalled with devices in it. Insert only empty
tubes in output tube holders while a Task is running.
The number of parts-per-tube parameter on the TaskLink screen is
incorrect. Check the 2500’s display for the number of parts per tube. If it
is incorrect, press
STOP
and
LOWER CASE
+
T
on the 2500’s keyboard.
Change the part count on the keyboard if it is incorrect. Press
ENTER
and
then
START
to continue running the Task.

Adjusting Dot
Matrix Print Head
Gap
The print head gap is set at the factory and will not usually need to be
changed. If there are substantial changes in the thickness of the label or
label backing, however, you may need to make an adjustment. If the gap
between the platen and the print head is too wide, it may result in slanted
or fuzzy printing. If the gap is too narrow, the print ribbon may rub
against the labels, smudging them and making the background gray.
CAUTION: Dangerous high voltages are present. Do not perform this
procedure while power is on to the 2500. This procedure
should be performed only by a qualified service technician.
To adjust the print head height, follow these steps:
1. Turn off and unplug the 2500.
2. Remove the ribbon cartridge and labels.
3. Locate the two corner screws on the main plate that hold the plate in
position. Loosen these screws so the plate is free.
4. Lift the main plate so you can see inside the 2500’s base.
5. Locate the four hex screws on the back side of the print head that
hold it in position. Loosen the screws, but do not remove them.
6. When the print head is free to move, move it as far to the right as
possible, then adjust the gap between the print head and the
underside of the platen to approximately 0.018 inches.
7. Hold the print head in this position and tighten the four hex screws.

Adjusting Position
of Print on Label
(Dot Matrix Printer)
The left-to-right position of characters on the label is determined by label
calibration.
You can change the label calibration setting during a Task run by
pressing
STOP
and then
LOWER CASE
+
C
. The 2500 displays:
The
X
represents the current setting. The default setting places the first
column of print within 0.040 inches of the leading edge of the label.
Increasing the value one unit moves the print location approximately
0.005 inches to the right; decreasing the value moves it 0.005 inches to the
left. Enter a number from 0 to 255, and press
ENTER
.
If you change label calibration, press
CAL
to calibrate the label (see page
4-19).
Adjusting Position
of Label on Device
(Dot Matrix Printer)
The position of the label on the device is determined by the label
placement value. This is set in the system defaults to “Auto center,”
which instructs the 2500 to place the label on the true center of the device.
You can change label placement using a local mode command described
in Appendix F.
You can use the
Label Adjust
parameter to fine-tune label placement and
thereby adjust its centering while a Task is running. Press
STOP
and then
LOWER CASE
+
A
. The 2500 displays:
Enter a number from 0 to 255; each unit moves the label 0.01 inch closer to
the trailing edge. Press
ENTER
to accept the selection.
Note: This works only when “Auto center” is selected in the 2500 Setup/Labeler
menu.
