I have new HP cartridges in my 6515. The black cartridge will not print. Alignment fails.Only blue ink will print on the alignment page. All other cartridges are working. I have a 564XL black cartridge and 564 color cartridges.
I am terribly sorry for the wrong link. I normally check them behind myself, but somehow missed this one.
Please click here for the correct print quality document. This document is for the Photosmart 6515 as you mentioned.
If the alignment is failing, then the printer is detecting the problem with the black printout. There is a document with steps to help troubleshoot alignment failed condition.
This document can be found here.
Let me know how it goes.
