SOURCE: HP L7680 Print Heads need real cleaning!
If the ink has dried up in the nozzles try putting a wet cloth in the microwave to get it hot enough to produce a little steam and set the cartridge, nozzles down on the damp cloth until ink starts to ooze from the cartridge. May require a couple of tries. Try using the cleaning program again.
Be careful not to touch the copper contacts on the cartridges.

You can get a download of the manual from HP:

The self-clean cycle of the cartridges can be accessed from the LCD or the software on your computer.
To manually cleaning the cartridges:
Remove the cartridge from the printer. Dip a cotton swab in distilled water and squeeze out any excess water. While holding the cartridge by its top, wipe off the face and edges of the cartridge. Do not wipe the nozzle plate (that could damage the cartridge). Replace the cartridge in the printer. Please note: if the cartridge is out of the printer for more than 30 minutes, the ink could start to dry out and not be usable.
The print heads are part of the cartridge.
I hope this helps.

By manual you mean that it needs windows to clean it right? (you cannot physically clean it yourself) Go to your printers, right click and in properties somewhere you should find "clean heads" somewhere. Try print test after. Should be good.
