When setting the reference scale and adjustment pattern on the
scanner, observe the following instructions:
Position the top right corner of the reference scale at the
scanner origin and set the reference scale in such a position
that its right side is in close contact with the document table
glass end.
Place the adjustment pattern along the reference scale as
shown at right. In doing so, position the adjustment pattern so
that it is in parallel with the reference scale and there is no
clearance between them.
