Hand Held Products IT4600, IT4X80, IT4800, IT4710, IT4410 manual MicroPDF417, is the Encoded Message

MicroPDF417

In rare instances where neither a valid Start nor Stop pattern is measurable, yet the symbol is somehow read, lines {8} and {9} are replaced by a message to that effect. The message is either:

"[F] < Start/Stop Decode Fails" in a Full Report or "Start/Stop Characters are Bad" in a Screening mode.

In Screening modes, it often occurs that none of the parameters are below the Minimum Acceptable grade. In this case, the final PQA line becomes:

"All Measurements within range".

MicroPDF417

The Full Report from a typical scan looks like the following (line numbers have been added in curly brackets):

{1} This is a typical Micro PDF417 symbol {2} >>> PQA from HHP <<<

{3} MICROPDF: 15 rows x 3 cols, 24 data & 21 chks {4} X roughly = 0.015"

{5} [A] < Row Height = 1.8 X

{6} [A] < Data Safety Margin = 100% (0 Erasures & 0 Errors)

{7} [A] < Edge Accuracy = 70%

{8} [A] < Print Growth = +4% of X

where:

{1} is the Encoded Message.

{2} is the Banner heading.

{3} identifies the Symbology, MICROPDF (or one of its derivatives: COMPOS- ITE-A, COMPOSITE-B, or TLC39), and lists other characteristics of this symbol: the height and width, and the numbers of data and check, or error correction characters.

{4} presents an approximate X-dimension.

Note: The reported X-dimension is approximate and based upon use of the IT4410LR at 4.7 in (12 cm) (see "Reading Techniques" on page 1-1). If you use different image engines, the X-dimension will vary. If you hold the reader closer than 4.7 in (12 cm), it will have the effect of reporting a larger than true X-dimension. Conversely, if you hold the reader farther away than 4.7 in (12 cm), it will have the effect of reporting a smaller than true X-dimension. Please contact HHP Application Support for additional information. Refer to Chapter 3 for contact information.

{5} lists the average Row Height, assigning the grades as:

1 - 8
