cleanliness, wrinkles, etc., or
an obstructed validator beam.
If there is no validator beam at
all, or if the LED is not flashing
as barcodes pass through the
validator beam, recycle
validator power. If the problem
persists, contact your service
representative.

number of missing
barcodes (on the form)
that caused the
warning/fault to be
declared.
Check that the validator signal
cable is securely connected to
the validator unit.
