@Bearsman, Welcome to the HP Support Community! I’m here to help.

I understand you are not able to use the printer due to this false error.

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.

Kindly perform the steps mentioned in this document - An 'E4' Error Displays (Paper Jam).
