Formax 6606 Series - Manual (Page 113)

OMR basic license
For the OMR basic license the following functions are available:
• Start mark: indicates the start of the code.
• Insert/Accumulate: defines when a document set is complete and must be inserted
into an envelope.
• Parity check: by adding a parity mark the reading code can be checked. The sum of
the marks must be even.
• Safety Mark: is used as an extra security (only 1-track OMR). With skewed paper
the reading head can miss part of the reading code. In these situations the safety
mark is not read, and the system will give an error. The safety mark also indicates
the end of the reading code. This mark must always be present on the document if
it is part of the code definition.
The minimum code is one mark in one line (insert). However for reliability it is advised to
use at least 2 marks. The first line is the start mark. A mark printed on the second line
means insert. No mark on the second line means accumulate.
