Table 6. Message List
Explanation
Overall data validation failure:
decodeability, percent
decode, defects, modulation,
EC Min, Rmin, and/or Symbol
Contrast.
Data validation failure:
decodeability. The difference
between wide and narrow
elements is too close for the
validator to reliably discern.
This usually indicates an
improperly set
heat/speed/pressure
combination or the loss of a
printhead element.
Data validation failure:
percent decode. The validator
detected gross
inconsistencies within the
height of the bar code. These
types of failures are likely
attributed to large blemishes
within the bar code, caused by
ribbon wrinkle or debris on
media.
Data validation failure:
hardware defect. The
validator detected unexpected
dark spots in spaces or light
spots in bars. This usually
indicates a poor ribbon/media
combination, a dirty printhead,
or a burned pixel.
Solution
1. Press PAUSE to clear the
message.
2. Adjust the parameter that
is causing the failure. To
see which parameter is
failing, run a Scan Report
(62).
3. Lower the Overall Grade
to a point where the worst
parameter grade will be
above the Overall Grade
threshold.
1. Adjust Print Intensity and
Print Speed in the QUICK
SETUP menu or via host
software.
2. Adjust the printhead
pressure. (Refer to the
Administrator's Manual.)
1. Check for a wrinkled
ribbon or debris on media.
Roll wrinkled area onto
take-up spindle.
2. Adjust the printhead
pressure blocks. (Refer to
the Administrator's
Manual.)
1. Check that paper and
ribbon are clean,
unwrinkled, and installed
correctly.
2. Clean the printhead.
3. If message reappears,
replace the printhead.
