3. Touch "Quick test" to print the Quick test page.
4. In the Registration menu, select the right margin setting.
5. To determine the margin setting, choose the value that is next 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.
