Hi @Tusher2806,

Welcome to HP Support Community. 
Thank you for posting your query, I will be glad to help you.

I see that you are facing cartridge issues with your HP OfficeJet Pro 6968 All-In-One Printer.

Please note that you need to replace all the cartridges for the printer to work as the ink levels of the color cartridges are empty.

If all the cartridges are replaced then please follow the steps listed below to clean the cartridge contacts.

1. Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.

2. Remove the cartridge indicated in the error message from the carriage.

3. Wipe the copper-colored contact on the cartridge with a lint-free cloth.

4. Reinstall the cartridge.

5. Repeat these steps for any other cartridges indicated in the error message.

6. Close the door or lid to the cartridge access area.

Let me know if this works.

Take care and have a good day.
