Printhead assembly electronic adjustment
A step-by-step process to align a new printhead.
Note:  Before aligning the printhead electronically, first align the printhead mechanically, if needed. See 
“Printhead assembly mechanical adjustment” on page 3-15
1.Enter the Diagnostics menu. See “Accessing service menus” on page 3-1.
2.Press   to enter the Registration menu.
3.Press   to print the Quick test page.
Quick Test page
(sample only; use actual sheet)
4.In the Registration menu, select the right margin setting. 
5.To determine the margin setting, choose the value that is closest to the darkest bar on the center graph of 
the margin page. Add that value to the current right margin setting printed on the left hand side of the 
margin page. (The right margin setting will also appear on the operator panel display.) For example, if the 
right margin setting on the page is -2, and the number that is closest to the darkest line on the graph is 3 
(-2+3), then the right margin setting will be equal to +1.
6.Press   or  , to the desired setting, and press  .
7.Print the Quick Test page again and check that the darkest line in the center graph is equal to zero. If it is, 
then check to see if the left, top, and bottom margins are detected. If it is not, then repeat step 5.
 
Note:  The alignment of the left margin positions the black plane to the right or left. The alignment of the right 
margin does not alter the margins and should only be used to adjust the printhead.

Printhead assembly mechanical adjustment
A printhead needs to be correctly positioned after it has been removed. Use a pencil to mark the screw locations 
of the old printhead on the metal frame. Align the new printhead relative to the location of the old printhead.
Note:  Skew is caused by a sheet being fed through the printer while misaligned. The entire image is rotated 
relative to the sheet edges. However, a mechanically misaligned printhead causes the horizontal lines to appear 
skewed while the vertical lines remain parallel to the vertical edges.There are no adjustments for skew. Check 
the pick roll (paper pick assembly) for wear, the paper path for obstructions, the fuser for proper setting, and the 
tray paper guides for fit to the media.
To adjust the printhead:
1.Enter the Diagnostics Menu. See “Accessing service menus” on page 3-1. 
2.Select PRINT TESTS.
3.Select Tray 1.
4.Select Single.
5.Fold the printed test page on the left side so that a few millimeters of grid lines wrap around the outside of 
the fold. See photo below.
6.Fold a second vertical fold near the center so that the left side top edge aligns with the right side top edge.

7.If the grid lines of the right flap align below the corresponding lines on the left flap, then adjust the printhead 
clockwise relative to the printer and recheck. (See the left side of the figure below.) If the grid lines of the 
left flap align below the corresponding lines of the right side, then adjust the printhead counterclockwise. 
(See the right side of the figure below.)
8.After obtaining a properly adjusted image on the paper, tighten all three screws.
Note:  The printhead must be aligned electronically. See “Printhead assembly electronic adjustment” on 
page 3-14.
