Skew
One printhead houses the four color planes. The black plane is aligned to the printer, and the other color planes
are internally aligned to black. Electronic alignment fine tunes the alignment of the color planes to the black
plane once the printhead is installed. See
“Alignment Menu” on page 3-11
for instructions on setting printhead
alignment. This must be performed before color skew adjustment is attempted. The following illustration shows
proper alignment versus skewed alignment.
