Alignment
Looking at patterns D, K, and L, you may nd problems with the printer’s printhead alignment, which can
cause defects such as the following.
Additionally, misalignment problems can be seen 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 dened or a third
color appears between them.
Finally, a special pattern for checking the printer’s printhead alignment can be found 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.
