Hi @Mrbelsky,

Welcome to HP Support Community.  

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

If you're encountering a question mark and your printer is not printing after replacing the cartridges, there are several possible reasons and steps you can take to troubleshoot the issue.

Check Cartridge Installation:

• Ensure that the cartridges are properly installed. Make sure they are securely and correctly placed in their respective slots.
• Double-check that you removed any protective tapes or covers that may be on the new cartridges.

Printer Compatibility:

• Confirm that the replacement cartridges are compatible with your HP 7800 printer model. Check the printer manual or the official HP website for a list of compatible cartridges.

Restart the Printer:

• Turn off the printer, unplug it from the power source, and wait for about 30 seconds. Plug it back in and turn it on. This can sometimes resolve temporary glitches.

Update Printer Drivers:

• Ensure that you have the latest printer drivers installed on your computer. Outdated drivers can sometimes cause printing issues.

Check for Firmware Updates:

• Check if there are any firmware updates available for your printer. HP often release updates to improve performance and address issues.

Run Printer Diagnostics:

• Many printers have built-in diagnostic tools. Check your printer's manual for instructions on how to run diagnostics or nozzle checks to identify and resolve printing problems.

Inspect for Jammed Paper or Obstructions:

• Open the printer cover and check for any jammed paper or foreign objects that may be obstructing the printing process.

Printer Software Troubleshooting:

• Use the printer software on your computer to check for any error messages or alerts. This can provide additional information about the issue.

Reset the Printer:

• Consult your printer manual for instructions on how to perform a reset. This can sometimes clear up minor issues.

By systematically checking these aspects, you should be able to identify and resolve the problem with your HP 7800 printer.

I hope this helps. 
 

Take care and have a good day.
