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” on page 3-7 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.
Quick Test
The Quick Test contains the following information:
• Print registration settings
• Alignment diamonds at the left, right, top, and bottom
• Horizontal lines to check for skew
Skew -100 to +100
Each increment corresponds to
1/1200 of an inch.
The default is 0.
A positive value causes the left end of the scan
line to move down the page. A negative value
causes the left end of the scan line to move up
the page. The right end stays fixed. There is no
compression or expansion of the image.
