Printer Fault Messages (continued)
Description
The Scanner could
not successfully
pass a bar code.
Note: This is a
normal condition
when a bar code is
not readable.
The printer has
shutdown to allow
the printhead
temperature to
cool.
Possible Solution(s)
Press the FEED Key to clear.
If the bar code is free from
anomalies (e.g., voids,
insufficient quiet zones, etc.)
yet the fault continues, try the
following:
1) Ensure that the bar code is
capable of being read by
the scanner; see the list in
Appendix B.
2) Increase the Heat value.
3) Enable only those bar
codes to be decoded.
4) Decrease the Print Speed
or increase the height of
the bar code.
5) Decrease the Verification
Level.
6) Ensure the ribbon used
contains carbon-based
inks.
7) Ensure that the label stock
has a matte finish.
If the fault does not clear,
and the bar code is readable
on other scanners, possible
misalignment; consult the
Linear Scanner Operation
Instructions, or call for
service.
Turn 'Off' the printer until
cool to prevent permanent
damage due to an excessive
printhead temperature.
