Adjustments
Printhead assembly adjustment
The printhead needs to be correctly positioned after it has been
removed. Align it to the frame or use the same position as the
removed printhead.
Skew is caused by a sheet being fed through the printer while
misaligned. The entire image is rotated relative to the print media
edges. However, a misaligned printhead causes the horizontal lines
to appear skewed while the vertical lines remain parallel to the
vertical edges.
To align the printhead:
1.
Enter the Diagnostic Menu. See
“Entering Diagnostic Mode”
on page 3-2
and print the Quick Test. To print the test:
a. Select
Print Tests
from the Diagnostic Menu.
b. Select
Tray 1
.
c. Select
Single
. The Quick Test prints.
