Polygon printhead mechanical registration adjustment
Do the printhead mechanically registration adjustment whenever you remove or replace the printhead or loosen
the mounting screws.
Install the new printhead with the mounting screws centered in the slots in the printhead frame assembly. Leave
the screws loose enough to allow the printhead to move from side to side within the slots. It is necessary to
perform a mechanical registration adjustment before locking down the three printhead mounting screws.
Note: In the case of paperfeed skew, go to “Alignment assembly adjustment” on page 4-3.
To perform the mechanical registration adjustment:
1. Turn the printer off.
2. Press and hold 3 and 6 to enter the diagnostic mode.
3. Turn the printer on, and release the buttons when Performing Self Test displays.
4. Select Registration from the menu.
5. Select Quick Test Page. The test page should only be printed on letter or A4 paper from Tray 1. The Quick
Test Page consists of alignment diamonds, horizontal lines that can be used for mechanical registration
adjustment. An example of the printhead alignment printout is shown below:Check the Quick Test Page for
any sign of misalignment by checking the diamonds at the top left and top right of the test page for equal
distance from the top of the page. If necessary, rotate the printhead to the left or right and tighten down the
mounting screws and check for proper alignment again by running another Quick Test Page. This
procedure may take two or three attempts before you get satisfactory results.
6. When you have the correct adjustment, ensure that the printhead mounting screws are properly tightened.
