Hi @dadokat,

Welcome to the HP Support Community.

I understand that you are facing issues with cartridge errors. I'd like to help!

Follow the steps to resolve the issue-

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 electrical contacts

Remove any debris or buildup from the contacts on the cartridges.

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

Push in on the cartridge indicated in the error message to release it from the carriage.

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

Slide the cartridge into its color-coded slot until it clicks into place.

Repeat these steps for any other cart access area.

Hi @JDJNR,

Welcome to the HP Support Community.

I understand that you are facing issues with cartridge errors. I'd like to help!

To provide you with an accurate solution, I'll need a few more details:

Have you signed up for HP instant ink program?

Do you get any specific error messages on the printer screen or on the computer screen?

Have you tried to clean the ink cartridge contacts?

Have you tried to use a single cartridge and check for a defective one?

Have you tried to use old cartridges and check if that helps?

In the meantime, let's try these steps here: 

Perform a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector.

Remove all the ink cartridges and then try to perform a hard reset on the printer.

With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.

Remove the USB cable, if present.

Wait for 2-3 minutes, and press and hold the power button on your printer for about 30 seconds to remove any additional charge.

Now plug back the power cable straight into a wall outlet without any surge protector or an extension cord and then plug back the power cord to the printer.

Turn on the printer and wait till the warm-up period finishes and the printer is idle.

Now insert the ink cartridges and then try to print a test page and check if it works.
