HP L7680 Print Heads need real cleaning!

Yes it might be a problem with the print heads. You can try cleaning printheads under tools menu. After cleaning printheads click on Align Printer in Tools menu and that will solve your problem. If not then you might need to replace the printheads. If you these print heads are less than 2 years then HP will replace it for free.

This could be a number of different things , and not connected to each other.
1. Non HP Ink jet cartridges . 2. Refiled cartridges. Always had problems with them. 3. Re alignment of cartridges. 4 and finally, print heads need cleaning...
Hope this helps..

Try cleaning the print heads. Or replace the two colors it's asking for magenta and cyan.

The print heads on most modern printers are built into the cartridge. Most printers have a "cleaning" cycle if you are getting bad prints.
If there is another reason you need them let us know and I can re-visit the question

Try printing a Diagnostic page or clean cartridge. Looks like the printheads might be clogged due to low usage or general wear and tear, they may not be working as desired.

There is some problem with your print heads. Run a print diagnostic report and see if it helps. You also may want to trigger clean cartridges if triggering print diagnostic page does not help.
This issue may happen if the printer is not used for few days. Recommend to keep the printer powered on always, or then trigger print diagnostic page as it tries to unclog the blocked print heads to give you a clean print.
Hope this helps.

Place a soft clean tissue paper over the cartridge print head and leave for about eight minutes. You can secure it with the aid of a rubber band. It should be held firm ok. If the tissue paper is not dampened by ink then the cartridge would have gone bad or the ink dried. You also know that they have expiry date and could go bad while yet in the packaging b/c it has expired. Good luck

Sometimes the circuit strip that sits at the back of the printhead carriage is the problem due to moisture, ink soiling, etc...

To clean these you need some cotton buds (like you use to clean your ears) and gently clean the area at the back of the printhead carriage (where the printheads slot into).

This removes any ink, or moisture that could be causing a short circuit or similar.
