The scanning beam does not
come on. 1. Make sure the power/data cable is plugged
into the validator and the controller board on
the printer. See “Installation and Removal”
on page 17.
2. Make sure the validator has not been
disabled in the VALIDATOR menu. See
“Enabling and Disabling the Validator” on
page 53.
3. Print a bar code validation demo page
(page 44).
4. Press the RESET button to turn the
scanning beam on (page 48).
5. Call your service representative if the
problem persists.
The scanning beam does not
cover the entire width of the
labels being printed. 1. Use Beam Shift to move the beam
horizontally to cover the entire width of the
labels. See “Shifting the Scanning Beam” on
page 41.
2. Use Beam Width to adjust the width of the
scanning beam. See “Beam Width” on
page 82.
The printer pauses after scanning
each label. If you have an RFID encoder but are not
encoding RFID tags, make sure RFID Reader is
set to Disable (in the RFID CONTROL menu).
