Lexmark T652 - Alignment Assembly Adjustment

8 Press the down or up buttons to the desired setting, and press the Select button.
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 236.
Do the reference adjustment if you are sure the margins are set correctly.
1 Loosen the locknut on the inside rear of the alignment assembly.
2 Remove the two screws holding the alignment assembly to the left side frame.
3 Back the reference adjustment screw out far enough to allow the alignment assembly to be removed from
the printer. It is not necessary to completely remove the screw.
Allen wrench
4 Install the new alignment assembly. Turn the reference screw clockwise with a 7 mm M3 Allen wrench until
it touches the back of the reference plate, and tighten the nut with a 5.5 mm wrench.
The reference adjustment screw can be adjusted without loosening the nut. Turn the screw clockwise a few
turns and print a copy of the Quick Test Page as you check the diamonds on the left margin. Continue adjusting
the screw as you check the results of each adjustment on a new test page until you obtain the results you want.
