NOTE:

The hex values listed above reflect single failures.

Multiple failures will create additional hex values based on the binary
weighting shown.

For example, the hex value

0042

(or binary

0000 0000 0100 0010

)

represents both the Encodation and Decodeability failures.

RFID

This is the hex value assigned for an RFID failure.

0 = no RFID failure

1 = RFID failure

7. Failure Message

Bar Code

Failure data is grouped into different types of failure, each of which defines a
bar code problem.

Checksum:

This occurs when the bar code is not properly encoded with

checksum digits.

Decodeability:

This occurs when the difference between wide and

narrow elements is too close to reliably discern. This is generally an
indication of an improperly set heat, speed, or pressure combination, or
the loss of heating element.

Defects:

This is a measure of unexpected dark spots in spaces or light

spots in bars. It is generally an indication of a poor ribbon or media
combination, a burnt pixel, or the printhead needs cleaning.

Encodation:

This occurs when the bar code is not properly encoded. For

example, a checksum is incorrect, a required number of characters is not
met, or required terminator characters are missing. This is usually an
indication of poor form or host application design.

Internal Data Format Error:

The bar code data format is invalid.

PDF 417 Gap:

This occurs when there are large gap damages (such as

ribbon wrinkle, voids, spots, etc.) within the PDF 417 data body code.
