I installed HP Smart. All options are working. When I choose for Support pages printing quality to clean the printer heads, a window appears with the options Align and Clean (next to each other). If i click on one of these buttons, the edge lines become black but only a small windows appears with the text Solve this problem and select Again. I can choose then between Cancel and Again. If I click on Again, the same window appears. Now I cannot clean and align the printer heads, because I see no other option in the driver program. Sorry for the possible wrong translations from Dutch.
