No kidding - where'd the ink go? I used my HP Photosmart D7560 three times in 18 month (hate to waste ink and paper, usually print to file), never got my cd's labeled and only managed to get less than 70 pages black. Then replaced all the cartridges again with the OEM product. For the color, the only time in the first year it was used was to align the printer and the cartridges were empty... HONEST!!! The second time (and is now the last) I replaced all the cartridges and had to align the printer - GUESS WHAT the ink is GONE again. I paid well over $100 for all 10 ink cartridges and shipping and got nothing but a few black text documents and NO COLOR documents at all but the alignment sheets.
I have NEVER been so screwed by anyone let alone HP and I swore by them. No more - I will probably never do business with them again. I sent a complaint and am waiting for a response - but NOT holding my breath.
I will NEVER recommend an HP to anyone after all this. Unfortunately, one of my dearest friends works for HP so I have to tolerate hearing some things about them but at least they will NEVER rip me off again.
