6. Within a few seconds the CALIBRATION and READ light will turn off. This indicates
a successful calibration.
NOTE: If the calibration light is still on or flashing, the calibration has failed. In this
case, refer to Table 2 on page 40 to repeat the calibration procedure or to
reset the validator settings back to the last good calibration settings.
7. Once you have a successful calibration, remove the calibration bar code card.
8. Power the printer off, wait a few seconds, then power the printer on.
If the calibration was successful, the scanning beam is on and the CALIBRATION
light is off. If the calibration was not successful, the scanning beam remains on and
the CALIBRATION light stays lit without flashing. Repeat the calibration procedure.
If repeated attempts fail, check the room for excessive ambient light, including direct
sunlight. You may need to move the printer to a darker area of the room.
NOTE: In some cases the validator can detect and indicate to the printer that
calibration is required. See "Calibration warning" in Table 6 on page 79.

Bar Code Validation Demo Page

The bar code validation demo page allows you to test or demonstrate the validator
operation without a host computer. This page contains some text and two good bar
code symbologies: one in Code 39, the other in Code 128. (Min. label size 2" W x 1" L)
NOTE: In the QUICK SETUP or MEDIA CONTROL menu, if Label Length is set
between 0.5 and 1.0 inches, only the Code 128 bar code will print.
