Aligning the printhead
There is one printhead that houses the four color planes. The black plane is aligned to the printer, and the color
planes are aligned to black. After you install the printhead and adjust the course alignment with the alignment
screws, use the Diagnostic menu to fine tune the alignment.
Dual diode alignment
1.
From the Diagnostic menu, select DUAL DIODE ADJUST, set the values of the colors (Black, Cyan,
Magenta, and Yellow) to 0, and save.
2. From the Diagnostic menu, select Diode Alignment Page.
An alignment test page prints.
If the alignment is correct, the color bars on the page should look solid in the middle (between 1 and -1)
with white lines starting to form near the top and bottom of each bar.
3. If the solid color area of a bar is above 1 or below -1, then adjust the Dual Diode value for that color. Enter
the number nearest the center of the solid color area to adjust it.
Example: The solid color area on the following test page is closer to -4 than 0. Enter -4 for the value to
adjust the position of the solid color area back toward 0.
4. Reprint the alignment page and make adjustments as needed until you are satisfied with the alignment.
