Sensor
Error
Error
The scanner has
an in-the-beam
sensor, which
provides timing
for the decod-
ing of barcodes.
The scanner
monitors this
signal, and
posts this error
if the signal is
sporadic or
missing.
- The scanner
stops reading
barcodes.
- Put the scan-
ner in the test
mode to test its
ability to read the
barcode (see sec-
tion “Diagnos-
tics | Read Test”
on page 176
) .
This is an internal
failure and is not
field serviceable.
