From your computer, click Start > All Programs > HP > HP Photosmart 5510 series > HP Photosmart 5510 series. HP OFFICEJET 5510 ALL IN ONE SCANNER DRIVER DOWNLOAD - The HP Officejet uses a two-cartridge system, one cartridge contains black ink, the second is a tri-color cartridge. I cannot get my HP Photosmart 5510 printer to print black, all other colours work fine, I have tried wiping the head with cloth and the cartridge, still not working.
Going through your post, it looks like a scanner failure issue with your printer.
