Hi @piggpenn 

Welcome to the HP Support Community!

Thanks for posting your query! We're here to help you get back up and running.

I understand you are getting Error code 11. Let's narrow this down so we can find the best fix.

• What’s the printer model? (Different HP models handle error codes differently.)
• Are you using Windows, Mac, or a mobile device?
• Is the printer connected via Wi-Fi, USB, or another method?
• Did this happen immediately after installing the toner, or was the printer working before?
• Are there any additional error messages on the display?

Once you share these details, I’ll provide steps to remove Error Code 11.

In the meantime, here are some general troubleshooting steps to resolve it:

Basic Fixes

Restart the Printer

• Turn off the printer and unplug it for 60 seconds.
• Plug it back in and turn it on.

Check the Toner Cartridge

• Remove the toner cartridge and reinstall it securely.
• Ensure it’s a genuine HP cartridge—some firmware updates block third-party toners.

Reset the Printer

• Press and hold the Power button for 30 seconds while unplugged.
• Plug it back in and restart.

Advanced Fixes

Update the firmware on an HP printer

• HP regularly releases new firmware versions for printer enhancements, app updates, or issue fixes. Update the firmware regularly to get the most out of your printer.
• Click on the link below for instructions on how to update the firmware of your printer.

Run HP Print and Scan Doctor (Windows Only)

• Download HP’s Print and Scan Doctor tool.
• Run it to diagnose and fix common printing issues.

Check Printer Configuration

• Ensure the printer is set up correctly in Control Panel > Devices and Printers.
• If using duplex mode, disable it when printing envelopes.

That is the issue the firewall is blocking the third party toner.   I don't know how to revert back a firewall.  The toner is a W1340a

Thanks for getting back to us.

I see that you have an issue using non-HP ink cartridges/toners on your printer.

Please refer to the below links for more information related to your issue.

If you are using generic or non-HP ink cartridges and the above links do not help. You will have to contact the generic ink cartridge manufacturer to assist you further with it, or you will have to use genuine HP ink cartridges to resume printing.
