The example below illustrates a set containing eight sheet.

Gate 1, Gate 2

The Gate 1 and Gate 2 act as start - reading - marks. Each mark
sequense must always include the two Gate marks. If not, the sheet
will be detected as blank.

Sequence 1 - 2

The “Seq1” & “Seq2” marks are needed for the OMR reader to detect
that the sheets in a set are fed in the right order. The sequence is: No
marks, S1 mark, S2 mark, S1 and S2 mark, no mark and so on. Each
new group shall start with the sequence number 0 (no marks), see
examples below.

End Of Set (E.O.S)

To indicate the last sheet in a set, an ”End Of Set” mark is required.

Parity

There must allways be an even number of marks on each sheet. When
needed, add the parity mark.
