Registration

Note: If you need to perform alignment or registration, see
The following information is meant to explain the uses for the menu items.
Print registration makes sure the black printing is properly aligned on the page. This is one of the steps in
aligning a new printhead. It is also the first step in aligning the duplex registration. See
on page 3-18.
The settings available are Top Margin, Bottom Margin, Left Margin, Right Margin, Skew, and Quick Test.
Skew
One printhead houses the four color planes. The black plane is aligned to the printer, and then the color planes
are internally aligned to black. Adjust the skew mechanically by moving the printhead with a printhead
adjustment screw. See
alignment. Electronic alignment fine tunes the alignment of the color planes to the black plane once the
printhead is installed. Skew adjustment must be performed before color alignment is attempted. The following
illustration shows proper alignment versus skewed alignment.
