If there are no defects, then the printer and ink system are working properly. If you still see print quality
problems in your output, double-check your software settings and paper as described in the previous
solutions.
Cause: Print quality problems can have many causes: software settings, a poor image file, or the printing
system itself. If you are unhappy with the quality of your prints, a Print Quality Diagnostic page can help you
determine if the printing system is working correctly.
