If the printhead cleaning process completes, Diagnostic Print B is printed again and you are asked the same questions again. 11 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 image 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.
