Test Pattern 3: IMPORTANT Nozzle Print Test Use this test purely to confirm an error highlighted in Test Pattern 2:. Some of the printhead nozzle problems that you will see in this pattern do not mean you will not get perfect image quality results. The printer has internal corrections that will hide many nozzle defects. In this test all the 240 nozzles of each printhead are tested. For each of the four colors you will see the numbers 10 to 240 over the diagonally stepped lines in increments of 10. These numbers correspond to the nozzle number that prints each step. There are two printhead nozzle errors: n Nozzles not printing n Nozzles misdirected. 11-16

Test Pattern 3:
Nozzle Print Test
IMPORTANT
Use this test purely to confirm an error highlighted in
Test Pattern 2:
. Some of the
printhead nozzle problems that you will see in this pattern do not mean you will not
get perfect image quality results. The printer has internal corrections that will hide
many nozzle defects.
In this test all the 240 nozzles of each printhead are tested. For each of the four
colors you will see the numbers 10 to 240 over the diagonally stepped lines in
increments of 10. These numbers correspond to the nozzle number that prints each
step.
There are two printhead nozzle errors:
Nozzles not printing
Nozzles misdirected.
2
Different colors visible in the
spaces between some or all of
the columns (depending on
the color of the printhead that
is misaligned)
This is an indication of
vertical misalignment.
Example C
Refer to 11-20,
Color Alignment
Quality Test
and verify this problem.
See the recommended actions.
NOTE:
It is also possible that the banding was caused because you were using non-
HP media. The performance of your printer can only be guaranteed if you use
genuine HP media.
