Describe your Officejet Pro L7680 All-In-One Printer Problem I get the error message that my black ink cartridge is empty. I replaced it with a new one and still had the error msg. I went through the process of cleaning the print heads. Same error msg. So I ordered and received a new black/yellow print head and installed it. I still have the same msg that the cartridge is empty. What else could be the problem?

Hi rainbow1785,

To correct this issue, please follow the steps below. With the new cartridge inserted, reset the unit to its factory setting.

1. Unplug the power cord from the HP All-in-One.
2. Wait for 20 seconds.
3. Press and hold # and 3 while plugging in the power cord to the HP All-in-One.
4. Release the buttons after the HP All-in-One starts up.
5. The HP All-in-One will now be reset to factory defaults.

Hope it helps.

Thank you for using FixYa.
