Hi @SJL0916,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

If your HP OfficeJet Pro 6978 printer is displaying a question mark (?) on the screen, it typically indicates that there is an issue or error that needs attention. To resolve this, follow these steps.

• Check for Error Messages: Look for any accompanying error messages or codes on the screen. These messages often provide clues about the specific problem. Note down any error codes you see.
• Restart the Printer: Sometimes, a simple restart can resolve minor issues. Turn off the printer, unplug it from the power source, wait for about 30 seconds, and then plug it back in. Power it on again and see if the question mark disappears.
• Update Firmware/Software: Ensure your printer has the latest firmware and software updates. You can usually find this information on the HP website. Updating can often fix bugs or compatibility issues.
• Check for Paper Jams: Make sure there are no paper jams inside the printer. If there is any stuck paper, carefully remove it. Refer to your printer's user manual for guidance on how to do this properly.
• Check Ink or Toner Levels: If you're getting a question mark along with a message about ink or toner, check the levels of your cartridges. Replace any empty or low cartridges as needed.
• Inspect for Hardware Issues: Look for any physical issues with the printer, such as loose cables or damaged parts. 
• Reset the Printer: If the problem persists, you can try resetting the printer to its factory settings. Keep in mind that this will erase any custom settings, so make note of them before proceeding. Refer to your printer's manual for instructions on how to perform a factory reset.

I hope this helps. 
 

Take care and have a good day.
