If both the top and bottom margins are skewed (or mostly the bottom margin), then do the following:
• Adjust the aligner roller to make the leading edge parallel with the trailing edge. See “Aligner roller
adjustment” on page 403.
• Adjust the printhead to align both margins. See “Polygon printhead mechanical registration
adjustment” on page 405.
• The aligner roller may need adjustment again after the bottom skew is aligned.
Aligner roller adjustment
Perform the aligner roller adjustment after replacing the aligner roller. Always print a copy of the Quick Test
Page before making any adjustments to the aligner roller.
Note: When replacing the aligner roller, unscrew the reference adjustment screw just far enough to remove
the old aligner roller and install the new one. It is not necessary to completely remove the screw.
• If you have just replaced the aligner roller, see Step A.
• If you are only correcting the top margin skew, see Step B.
• If you are correcting the bottom margin skew or both top and bottom margin skews, see Step C.
Step A
Set the initial position of the aligner roller plate using a 3‑mm hex wrench at the aligner roller reference
adjustment screw (A).
