the front panel, indicate whether there are problems with them. The

sorts of problems to look for are:

 White streaks or bands in the solid blocks.

8 If you indicate that there are problems in the blocks of color, the

Printer will try and clean the Printheads that have the problem. A

Printhead can be cleaned up to 3 times in this way after which it will

need to be replaced (you will be informed via the front panel).

9 After cleaning the Printheads, the Printer reprints the Diagnostic

Print A, and you need to repeat the previous steps.

10 If you indicate that the blocks of color in Diagnostic Print A are

OK, the Printer will print Diagnostic Print B.

11 For each color in the pattern in Diagnostic Print B, you are asked

about the quality - look especially for missing lines. If you indicate

that a color is defective, the Printer tries to clean that printhead.

12 After cleaning the Printheads, the Printer reprints the Diagnostic

Print B, and you need to repeat the previous steps.

13 If none of the patterns or blocks in the 2 Diagnostic Prints show

any problems, it could be that the Print Quality problem is caused

by a wrong setting in the software, or maybe the print job should

have been printed with Print Quality set to Best instead of Normal

or Draft.
