HP Photosmart 8250 black ink problem

My HP Photosmart 8250 has suddenly developed a printing problem and I think it may be to do with the black ink cartridge as black does not appear correctly on colour prints. When I print out the extended self test diagnostic report, the printing on pages 1 and 2 is very faint, apart from the headings. In the print quality pattern section, black appears as light green. The black cartridge is relatively new (installed July 2011) and appears to be about half full. Although not an HP cartridge it is a recognised replacement and has an expiry date of August 2013 (according to the last successful test report).
I have tried the usual things like print head cleaning, print head realignment and even resetting the printer (using the Instant share/Photo tray reset method).
I am not getting any error messages on the printer and the problem has suddenly appeared without warning.
