Lexmark MS310 Series Service Manual

Printhead assembly mechanical adjustment
A printhead needs to be correctly positioned after it has been removed. Use a pencil to mark the screw locations of
the old printhead on the metal frame. Align the new printhead relative to the location of the old printhead.
Note: Skew is caused by a sheet being fed through the printer while misaligned. The entire image is rotated relative
to the sheet edges. However, a mechanically misaligned printhead causes the horizontal lines to appear skewed,
while the vertical lines remain parallel to the vertical edges. There are no adjustments for skew. Check the pick tires
for wear, the paper path for obstructions, the fuser for proper setting, and the tray paper guides for fit to the media.

To adjust the printhead:
1 POR into the Diagnostics menu, and print a Quick test page:
Diagnostics Menu > Cont Prt Simplex Tray 1
Note: Press
immediately after the paper picks to avoid printing more pages.
2 Fold the printed test page on the left side so that a few millimeters of grid lines wrap around the outside of the
fold.
3 Fold a second vertical fold near the center so that the left side top edge aligns with the right side top edge.
