Scanner Diagnostic Plot
Alignment
Looking at patterns D, K, and L, you may find problems with the
printer’s printhead alignment, which can cause defects such as the
following.
Misalignment problems is visible in patterns D and G in the form of
color fringing (which is exaggerated below, on the right). That is,
the limits between two strong colors are not well defined or a third
color appears between them.
Finally, a special pattern for checking the printer’s printhead
alignment is located at the top left of the diagnostic sheet. This
pattern has no number as it is not used for scanner checking. It is
made of three colored crosses that may be used to identify the
problem in question. The correct pattern is shown on the left, an
example of misalignment on the right.
