Identify the printhead transitions that need manual printhead alignment
(horizontal)
When to do
When you observe thin white or dark(er) lines along the length of the printed output, at positions
that correspond with the printhead boundaries, and the automatic printhead alignment procedure
does not completely solve the problem, you must identify the printhead transitions that need
additional manual printhead alignment. You can use this information to perform an additional,
horizontal manual printhead alignment on page
Before you begin
To identify the printhead transitions that need additional manual printhead alignment you need
the following.
• The printed output that shows the problem and that you printed after you performed the
automatic printhead alignment procedure.
• The automatic printhead alignment test print as a reference to identify the printhead
transitions.
The printhead transitions B and C are closest to the middle of the printed output,
approximately 10.8 centimeters from the middle. The printhead transitions A and D are located
approximately 32.8 centimeters from the middle.
Procedure
1. Place the automatic alignment test print on top of your printed output and mind the leading
edges and the trailing edges.
2. Align the middle of the test print with the middle of your printed output and mark, according to
the test print, the transitions A, B, C en D on your printed output.
