Bidirectional Alignment
If a Printer has Bidirectional alignment problems, lines are not
straight. The pattern shown below is designed to highlight this kind
of problem.
A pair of vertical lines is printed with each Printhead color except
yellow. Each section of the vertical line is printed by a different
group of Printhead nozzles (one quarter), in one pass. Check the
lines on this test pattern, if they have any defects like the ones
described above, perform the corrective action.
Solving Bidirectional Alignment Problems
1 Using the same media with which you were experiencing problems,
perform Printhead Alignment from the Printer Setup menu by
selecting Utilities/Calibration/Printhead Alignment. Please wait as
the process of aligning the Printheads takes a few minutes.
