Description of problem
This kind of problem can show itself in several different ways:
1 A thick colored band.
2 Thinner colored bands.
3 Discontinued colored blocks.
4 Thin lines.
Corrective Action
1 Clean the electrical connections of the Printhead that seems to be
responsible for the problem (in this example, the Magenta Printhead is
responsible).
2 Recover the Printheads (Ink Menu/Printheads/Recover Printheads).
3 Reprint the image with the same settings as before.

problem. If you are not sure which Printhead is responsible, use the Image
