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. 8. Press or to the desired setting, and press . 9. 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. Alignment assembly adjustment Do the alignment assembly adjustment whenever you replace the alignment assembly. Always print a copy of the Quick Test Page before making any adjustments to the alignment assembly reference adjustment screw. When replacing the alignment assembly, it is necessary to back the reference adjustment screw out far enough to remove the old assembly and install the new one. • If you are replacing the alignment assembly, go to step A. • If you are only adjusting the reference adjustment screw, go to step B. Step A Print a copy of the Quick Test Page and check the margin adjustments printed on the test page. These settings should be within the range specified in "Registration" on page 3-67. Do the reference adjustment if you are sure the margins are set correctly. 4-4 Service Manual
