Printhead assembly adjustments
Printhead assembly mechanical adjustment
A printhead needs to be correctly positioned after it has been removed. Use a sharp pencil or a small, flat-blade
screwdriver to mark the location of the old printhead on the printer 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.
