The Printer contains internal Diagnostic Prints to help you diagnose the possible source of some print quality defects. The Diagnostic Print is divided into five numbered parts:

1. Primary colors specifically designed to diagnose banding problems.

2. Color to color alignment.

3. Bidirectional alignment to check alignment when printing bidirectionally.

4. Vertical line straightness.

5. Nozzle print test to check each Printhead nozzle in a Printhead.
