Warning—Potential Damage: In some cases the adjustment process may take several tightening and loosening
cycles of the printhead mounting screws. Care should be taken to avoid stripping the mounting screw bosses.
Use only a manual hex head screwdriver, for this reason.
6 When you have the correct adjustment, ensure that the printhead mounting screws are properly tightened, and
print a final Quick Test Page for verification.
7 Check the top edge skew and perform the media aligner roller adjustment, if required. See “Media aligner roller
adjustment” on page 393.
