Lexmark E352DN Service Manual

Printhead assembly mechanical adjustment
A printhead needs to be correctly positioned after it has been removed. Align it to the frame or use the same
position as the removed printhead. An indicator is located at the front right-hand screw for reference.
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 roll (paper pick assembly) 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. Enter the Diagnostics Menu. See “Entering Diagnostics Mode” on page 3-5.
2. Select PRINT TESTS.
3. Select Tray 1.
4. Select Single.
5. Fold the printed test page on the left side so that a few millimeters of grid lines wrap around the outside of
the fold. See photo below.
6. Fold a second vertical fold near the center so that the left side top edge aligns with the right side top edge.
