Color Calibration of Printer

Printhead Adjustment - X, Y, and Theta
Test Print Pages
Printing the color calibration pages allows a service person to align
the Cyan, Magenta, and Yellow planes with the Black plane. The
planes must be adjusted in three different directions, the X direction,
the Y direction and the Theta direction. These values must be
adjusted for each plane. View the page in the portrait position when
you check these adjustments.
The X, Y, and Theta adjustment must be checked with the radar test
page found in the X Adjustment menu, (Test Print) sub menu.
Printhead Adjustment

moves the plane up the page. A negative offset moves plane down
the page.

entire plane to move up/down on the page.
Y Position Adjustment (Vertical)
Modification of this setting allows the users to adjust the color offset
of a color image for the page direction (Y).
Changing this parameter by 1 unit moves the image 1 dot unit. The X
position can be set from -128 to 127. A positive offset moves the
plane to the right of the page. A negative offset moves the plane to
the left the page.
Note: Modification of the y position adjustment setting causes the
