Lexmark T650 Service Manual page 325

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.
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.
