OMR Marks
OMR marks are horizontal or vertical black solid lines that are found on printed mailing
sheets. The mail processing machines check for these lines on every page that is fed into
them. The tracking of these marks triggers mechanical processes, such as the folding of all
pages that should be inserted together in an envelope.
The Bar Code Printing function can generate OMR marks that are used by insertion, folding,
or sealing systems found in mailrooms.
There is no standard for OMR marks. Specifications vary from machine to machine and per
OMR scanning software. However, the Bar Code Printing function can be configured to work
with any specification.
The OMR mark's width, spacing, and length can be defined by using the b, s, and v
parameters.
NOTE
• Some mail processing machines use thicker marks to indicate start and stop positions, while others
only use one type of mark for all processes.
• Marks in the data are defined from top to bottom.
Usage: Only three characters can be used as data for OMR marks: '0', '1', and '2'.
0: The mark is skipped.
1: Regular mark. (Thickness is defined by the first b parameter.)
2: Heavy mark. (Thickness is defined by the second b parameter.)
