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.

I have instructions on how to clean the printer cartridges and pinhead electrical contacts, but after messing with the machine for and hour, I am still unable to center the cartridges in order to extract them.  How is that done?

I understand you are receiving a "71.02.4A" error on the printer screen.

We can perform a factory defaults on the printer to resolve the issue

• The reset instructions are specific for your printer and performing those steps on a different printer may corrupt the device.
