6 In the Registration menu, select the right margin setting.
7 To determine the margin setting, choose the value that is closest to the darkest bar on the center graph of
the margin page. Add that value to the current right margin setting printed on the left hand side of the margin
page. (The right margin setting will also appear on the operator panel display.) For example, if the right
margin setting on the page is -2, and the number that is closest to the darkest line on the graph is 3 (-2+3),
then the right margin setting will be equal to +1.
