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
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.
