Solution/Explanation
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.
3. Modify Media > Image > Print Intensity or Media >
Speed > Print Speed.
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 paper and ribbon to make sure they are clean,
unwrinkled, and installed properly.
2. Clean printhead.
3. If message persists, replace the printhead.
This is a status message. The printer is in low-energy idle
