@jdfmorrison, Welcome to the HP Support Community!
I understand you are not able to print due to this error. Let us try these steps:
Reset the printer
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Wait at least 60 seconds.
- Reconnect the power cord to the rear of the printer.
- Turn ON the printer, if it does not automatically turn on.
- 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.
Check for any obstructions and close the cartridge access door firmly. You may refer to - Replacing the Ink Cartridges
Check for any paper jams inside the printer - 'E4' Error Displays (Paper Jam) Also, perform the steps mentioned in this document - An 'Out of Paper' error displays, printer does not pick paper
If the error persists, I'm afraid this is a hardware failure. Please reach out to the HP Technical Support team in your region regarding the service options for your printer.
You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.
