Setting the OMR Scanning Area

Material is scanned as it feeds through the machine. This means that
the OMR Scanner reads a vertical strip or margin down the page,
defined by the OMR Specifications on pages 5-9 to 5-12.
The machine must now be told if the entire OMR margin (the strip
down the page that is scanned for OMR marks) is clear of any other
printing or punched holes, etc.
If the area IS clear, the machine can normally detect the OMR marks
with no further setup (this is dependent on the type of code being
used).
If the entire margin is NOT clear, or the machine cannot set itself
automatically, it will ask questions to ascertain where it needs to look
for OMR marks and where it should ignore other printed matter.
Depending on the type of OMR code being used, the machine will
ask you to define either the first mark position and code length
OR the Clear Zone as described on the following pages...
