Adjustment Procedures
Printhead Assembly
This adjustment must be performed whenever the printhead is
removed, replaced or the printhead mounting screws are loosened.
An incorrectly adjusted printhead produces horizontally skewed
images down the page.
To perform the printhead 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 Print Test, Tray 1 and Single from the menu. The test
page should only be printed on letter or A4 paper from Tray 1.
The Print Test page consists of horizontal lines that can be used
for skew adjustment, page count setting, printer serial number
code levels and print registration settings.
5. Check the Print Test page for any sign of skew by folding the
paper in half (left edge to right edge). Check the horizontal lines
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,
perform the following:
a. Remove the top cover.
b. Loosen the three printhead mounting screws.
c. Adjust the position of the printhead.
d. Replace the top cover.
e. Print a Print Test page and check for skew again.
This procedure may take two or three attempts before you get
satisfactory results.
6. When you have the correct printhead adjustment, gently tighten
the three printhead mounting screws being careful not to move
the printhead assembly.
