In the Registration menu, select the right margin setting.
5.
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.

Press or to the desired setting, and press .
7.
Print the Quick Test page again and check that the darkest line in the center graph is equal to zero. If it is,
then check to see if the left, top, and bottom margins are detected. If it is not, then repeat step 5.
Note: The alignment of the left margin positions the black plane to the right or left. The alignment of the right
margin does not alter the margins and should only be used to adjust the printhead.
