Poor scanning
Check media
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. 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
User’s Manual .)
Poor scanning
Inspect head
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. 1. Check that paper and
ribbon are clean,
unwrinkled, and
installed correctly.
2. Clean the printhead.
3. If message reappears,
replace the printhead.
