HP L7680 Print Heads need real cleaning!

My l7680 print heads are simply not that old but they need to be cleaned.

The Cleaning programs in the HP software don't work. Isn't there some alternative method to really cleaning these Print heads

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.

There are gaps in my printing!!! The docs are missing lines...Is it the printheads or could it be an ink problem?


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.

How can print heads be accessed


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

HP L7680 won't print black, cartridge is new, says it is full, Self diagnostic page says printhead is good


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.

HP Officejet Pro L7680 When printing a power point presentation, lines are printing over the jpeg pictures on the slide


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.

HP all-in-one not printing cyan color


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

HP L7680 Print Head Problem


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.
