Always calibrate the labels (refer to the procedure on page 5-25) after
performing either one of the following operations:
• Installing a new roll of labels
• Changing the ribbon
• Adjusting the ADC reference value
• Manually moving the labels
To check and manually adjust the ADC value, follow the steps below:
1. Put the 2500 in local mode.
2. Select OPTIC TEST from the DIAGNOSTIC MENU and load labels.
3. Locate the ADC optic and ensure that a label is blocking the optic’s
beam to obtain the highest ADC optic value. The 2500 should
display:
4. If a label is not blocking the ADC optic, slowly turn the label advance
knob in the counterclockwise direction to advance the liner. The
value on the display fluctuates until the label blocks the optic and the
highest value appears. Do not begin the adjustment procedure until
you are certain that a label is blocking the optic.
If the ADC value is not in the range of 190 to 200, press
LOWER CASE

while in the Optic diagnostics menu. Press

or

until the displayed value reaches 200.
5. Turn the label advance knob until the ADC optic is reading only the
liner (it should read between 120 and 170, if the liner is opaque). The
liner reading is not adjustable because the range is variable.
Return to the Main Menu by pressing
RESET
. Press
CAL
to have the 2500
run a label calibration to adjust to the new setting.
Note: Adjust the ADC reference value for the label material you are using. If
you are using both Kapton and thermal poly label material, adjust the
ADC reference value for Kapton. If you are using thermal poly label
material exclusively, you may need to make only minor adjustments.
