Hi @Winnie_55- 

Welcome to the HP Support Community. 

I understand that you are facing issues with the Ink System Failure error and you have done a few troubleshooting steps.

I will be delighted to assist you here.

To assist you with accurate information I would require more information regarding this.

• Did you do any do any changes on the printer, like replacing the cartridges?

Meanwhile, perform a power reset

1. Turn on the printer, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Wait at least 30 seconds.
5. Plug back the power cable straight to a wall outlet without any surge protector and printer.
6. Turn on the printer.

Reseat the printhead up to three times

Slip your fingers into the slot on the left side of the printer, and then pull forward to open the cartridge access door. The carriage moves to the left side of the printer. Wait until the carriage is idle and silent before proceeding.

Unplug the power cord from the rear of the printer. Unplugging the printer prevents the carriage from moving.

   WARNING:

You must disconnect the power cord before reaching inside the printer to avoid risk of injuries or electric shock.
