Analyzing the Image Quality Print
Test Pattern 1: Primary Colors
The purpose of the particular part of the image Quality
Print is to test the overall quality of the document with
regards to dense colors.
The colored stripes are in the same order as they
appear on the printer as if you are facing it, that is, Light
Cyan first and Black last.
Each pair of colors is printed by only one printhead. So
it’s easy to find the root cause of the image quality
problem.
This array of colored stripes is designed to check for
certain defects with the printer. It should not be used to
check for color consistency or accuracy.
If your printer is functioning correctly this part
of the print will have no problems. There is no
banding in any of the colors.

image quality is not acceptable, you will need to
perform some corrective actions.

within the printed image. They can appear as light or
dark bands.
