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.
• 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” in “System Maintenance”.
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.
5. System Maintenance
