How to Correct Skew and Parallelogram/Trapezoid Distortion on a Small Test Page
Skew Correction
If the test page is so small that <j> is not
on the page, add an arbitrary mark <j'>
anywhere on the red line <h>� Then, enter
the distance from <j'> to the left edge of
the paper in [j]� Enter the distance from <i>
to <j'> in [h]�

Trapezoid Distortion Correction
If the test page is so small that the distances
b and h cannot be measured, add <c'>,
<b'> and <h'> as shown in the illustration
on the right� Enter these distances in [c], [b]
and [h] respectively�

Parallelogram Distortion Correction
If the test page is so small that <a> is not on
the page, add an arbitrary mark <a'> on the
red line <c>� Enter the distance from <a'>
to the leading edge of the paper in [a]� Enter
