HP 510 - Manual (Page 73)

Diagnostic Print B interpretation
1. For each color in the pattern in Diagnostic Print B, you are asked about the
quality—look for missing lines. If you answer that a color is defective, the
printer tries to clean that printhead.
If the printhead cleaning process completes, Diagnostic Print B is printed
again and you are asked the same questions again.
2. Afterwards, if problems with images remain, use the Troubleshooting
procedure again.
If none of the patterns or blocks in the two Diagnostic Prints shows any problem, it could be that your print
quality problem is caused by a wrong setting in your software, or perhaps the job should have been printed with
the Print quality set to Best instead of Normal or Draft.
If the Troubleshooting routine didn’t indicate that printhead alignment was necessary, you can select Align
printheads in the Ink menu to try to solve any further print quality problems.
