Data Matrix

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.

{6} lists the number of Module Errors in the central Core Symbol, which con- sists of the finder bullseye, four orientation clusters at its corners, and the mode message along its perimeter. The grade is assigned as:

Aif there are 0 (zero) errors,

Bif there is 1 error,

Cif there are 2 errors,

Dif there are 3 errors

F if there are 4 or more errors.

In Screening modes, this parameter is reported as "Too many Code Symbol Errors (3)" when that is the case.

{7} lists the Data Safety Margin. In Aztec Code symbols, the recommended number of error correction words is a minimum that is generally exceeded because any excess codeword capacity is filled with extra check words.

Thus this parameter often exceeds 100%, but it also can be forced to much higher or lower levels by user options.

{8} and {9} list the Horizontal & Vertical Print Growths, respectively. When one direction's growth is substantially larger than the other, excessive bar dragging in the direction of label travel is indicated and should be fixed.

When both directions have excessive growth, then either (a) adjustment of the print process or (b) undercutting of the original bar code symbol graphic is recommended.
