Reading Multi-Row OCR
The image scanner is capable of decoding multi-row OCR text.
Note: Reading rows longer than sixteen characters is not recommended.
Consider the following example. This example shows serial commands as they
would be entered using QuickView.
Example: You need to read multiple rows of OCR-A data as shown below:
12345678
ABCDEFGH
First, enable the OCR-A font. To read the first row of OCR data, you would
program the following template:
OCRTMP"dddddddd".
This template is the default OCR template. If you wanted to read the second
line of data, you would use the following template:
OCRTMP"llllllll".
To read both lines of OCR at one time, use the variable r to indicate the start
of a new row. All the other templating variables for the individual rows work
the same as previously described. For instance, in the above example, you
would use the following template to read both rows:
OCRTMP"ddddddddrllllllll".
To read the three rows below, you would use the template command
"OCRTMP"ddddddddrllllllllrlllldddd".

OCR Check Character
You may want to print and verify a check character in order to enhance the
security of your OCR application. The image scanner can be programmed for
almost any type of check character. A number of presets are provided for com-
mon check character uses (e.g., modulo 10 and modulo 36).
Scan the OCR Modulo 10 or OCR Modulo 36
Check Character
bar code to
specify the type of check character used in the OCR strings you’re scanning.
The image scanner will then only read OCR character strings with a valid check
