3.2.3 Encoding capacity
The capacity of the Data Matrix field depends on the size, as shown in Figure 30. If the
amount of encoded data is greater than the capacity, the printer displays an empty box
instead of the field. Increase the size of the field or decrease the amount of data.
NOTE: The Data Matrix format uses some capacity for error correction. Figure 30 shows
the maximum available capacity for numeric, alphanumeric, or binary data for each
symbol size. The printer sets the encoding mode automatically for the type of data
included in the symbol.
The Data Matrix field can use a number of standard methods to encode the source data. The
method that is used depends on the type of source data.
3.2.4 Remote fields
If the source data includes a remote field, the printer examines the format of the received
data. The data type is alphanumeric unless the field contains only numeric data. Make sure
that the received data contains the correct data type. If the data type is not correct, the
printer displays an empty box instead of the Data Matrix symbol.
