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.
