HP officeJet Pro 6978 cartridge problem

[Tpa3]

Printer said “one or more cartridges are damaged” so I replaced all the cartridges with brand new cartridges but I am still getting the same issue. I have had the same issue with another HP printer.

Welcome to the HP support community.

I understand that you are getting a cartridge error, I am glad to assist you.

Reset the printer

Reset the printer to recover from printer errors or failures.

1. If your printer has a rechargeable battery, remove it.

2. With the printer turned on, disconnect the power cord from the printer.

3. Unplug the power cord from the power source.

4. Wait 60 seconds.

5. Reconnect the power cord to a wall outlet and to the printer.

   NOTE: 

   HP recommends plugging the printer directly into a wall outlet.

6. Turn on the printer to complete the reset.

Clean the ink cartridge and printhead electrical contacts

Remove any debris or buildup from the contacts on the cartridges and in the carriage.

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. Place the cartridge to the side with the contact facing upwards.

5. Wipe the contact inside the printhead with a lint-free cloth.

   

6. Reinsert the cartridge into its color-coded slot, and then press down on it until it snaps into place.

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

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