Question about HP Officejet Pro L7680 All-In-One Printer
1. Take a paper towel and fold it over so it is four layers thick
2. Then soak the paper towel in Windex.
3. Then take the printheads from the printer and set them each (jethead down) onto the saturated paper towel.
4. Then press the bottom of the Printhead into the towel.
5. Then add more Windex and periodically press the heads into the soggy towel.
6. Repeat this a few times and possibly let them sit on the towel overnight.
7. Finally clean them off with rubbing alcohol and put them in the printer.
Basically what often happens is the jets with have dried ink on them and Windex is able to clean them out better than anything else.
