HP sent a signal to my 8610 to "break" it. It was a model that allowed recycled cartridges. I put new (recycled) ones in it and cleaned the print head. Colors came out fine. I left, when I got home it said the cartridges were damaged. I've spent over 8 hours trying to fix something simple just to find out that it was purposely done by HP. I loved it, now not so much.
