Description Value Direction of change
Top margin -50 to +50 
Each increment corresponds to 8 
scans at a 600 dpi scan rate (0.0133 
inches or 0.339 mm)
. 
The default is 0.A positive change moves the image down the 
page and increases the top margin. A negative 
change moves the image up and decreases 
the top margin. No compression or expansion 
occurs.
Bottom margin -25 to +25 
Each increment causes 
approximately 0.55 mm shift in the 
bottom margin.
The default is 0.A positive offset moves text down the page and 
narrows the bottom margin, while a negative 
offset moves text up the page and narrows the 
bottom margin. The image is compressed or 
expanded.
Left margin -50 to +50 
Each increment corresponds to 4 
pixels at 600 dpi (0.00666 in. or

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. Right margin -50 to +50 
Each increment corresponds to an 
approximate shift of 4 pixels at 600 
dpi.
The default is 0.A positive change moves the image to the left, 
and a negative change moves the image to the 
right.
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. Description Value Direction of change
