Welcome to the HP Support Community!

• Are you able to bypass this error message and go to the home screen of the printer?

I'm afraid this could be a possible hardware failure with the printer. Let us try these steps that may resolve this issue:

Step 1: Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.

2. Wait at least 60 seconds.

3. Reconnect the power cord to the rear of the printer.

4. Turn ON the printer, if it does not automatically turn on.

5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Step 2: Update the printer firmware if possible

Step 3: Check for any paper jam/carriage jam inside the printer

Check if the print carriage moves freely. Refer to this document for steps.

Let me know how this goes.

I still can not get by the error code. So the printer shows off line and I can not install the new drivers.
