I have an HP Photosmart Plus Printer. It uses theHP 564 Ink. My black ink cartridge was all out of ink and I changed my ink cartridge like I normally do. It registared that I had an new one in place. However, when I print the page is blank. It shows now error what so ever. I have done the clean print head option 3 times. I have done printer quality and status report. No black whatsoever prints. I have even put in another new cartridge. I have cleanded the copper wires where the inkcartridge makes contact with the printer. I don't know what else to do. The other color print just fine. Please help if you can. I followed all the instructions I found on the an link from HP Consumer Support for ink Cartridge Problem.
