4. Carefully push the OMAS fully up into its mounting so
that the OMAS window protrudes slightly ABOVE the
Center Platen (approximately 0-2 mm). To ensure the
OMAS is correctly positions, slide a sheet of paper
over the Platen Ribs until it is stopped by the OMAS.
This ensures the OMAS is protruding slightly above
the platen.
5. Slide a sheet of paper over the OMAS window, if the
paper is not stopped by the OMAS, repeat step 4 to
ensure the OMAS is pushed fully up into its the
mounting.
6. FULLY tighten the T-20 vertical attachment screw.
CAUTION: Make sure the OMAS is pushed
completely up into its mounting or you will
encounter an error during the OMAS
calibration because it will not be able to focus
on the paper.
