Printhead Assembly Adjustment
Do the printhead assembly adjustment whenever you remove or
replace the printhead assembly or loosen the mounting screws.
Install the new printhead with the three mounting screws centered in
the slots in the printhead frame assembly. Leave the screws loose
enough to allow the printhead assembly to move from side to side
within the slots. It is necessary to perform a registration adjustment
before locking down the three printhead mounting screws.
To perform the registration adjustment:
1. Turn the printer off.
2. Press and hold Return and Go.
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 skew
adjustment, page count setting, printer serial number code
levels and print registration settings.
6. Check the Quick Test Page for any sign of skew 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 any adjustment is
necessary, adjust the left or right printhead mounting screws
and check the skew again by running another Quick Test Page.
This procedure may take two or three attempts before you get
satisfactory results.
7. When you have the correct adjustment, gently tighten the
printhead mounting screws being careful not to move the
printhead assembly.
