try this link : I followed the directions and fixed the problem. the instructions that came with the new printhead weren't really complete.
Here's essentially all I did for my fix - Opened the printer top, turned the printer off. Removed the "bad" printhead, cleaned the metal contacts on the printhead and printer with windex. Closed the printer. Turned it on. waited for it to reset. Opened the printer. Turned the printer off again. Installed the printhead. Closed the lid. Plugged the printer in again. When it was ready I accessed the HP toolbox and alligned the printheads and cleaned the printheads. It worked. Here's a link with photos.

You need to go to the hp download site and download the System Maintenance Utility Software. Its free, but you need it before you can clean the print heads. also, for some reason it works best when hooked to the network, not directly to Computer.

SOURCE: HP L7680 print head problem
When installing the print heads out of the box you MUST shake them for 30-60 seconds, same goes for ink tanks. If you do not then the lubricant that is added to them will seperate and it will draw thinned out ink causing damage to the print heads. Also, if your system sits for more than a couple weeks (and this goes for ALL printers) then run a test page ence every 2 weeks to keep the system from drying out.
I used to work at a couple office supply stores and this was almost always the issue with bad printheads on HP, Brother and Cannon printers.
