Vertical Line Straightness
If a Printer has Vertical Line Straightness problems, lines are not
straight. The pattern seen below is designed to highlight this kind of
problem.
A pair of vertical lines is printed in each direction, comparing line
straightness for each Printhead color compared to Magenta.
Check the lines on this test pattern, if they have any defects like the
ones described above perform the corrective action.
Solving Vertical Line Straightness
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.
