I changed ink cartridges and now am getting an error C9C70000 and printer will not work

[cherylP1961]

Error Message C9C70000 after changing approved ink cartridges and closing top.  First, I received an error 0199CE7 stating that my printer was improperly shut off and to restart.  It kept given the same error.  I tried unplugging for a time and restarting and now I am getting a blue screen with an image of a power button and error code C9C70000.  Any help would be appreciated.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help,

I appreciate your efforts to try and resolve the issue. I understand you are receiving a "C9C70000" error on the printer screen.

Try the below suggestions-

Reset the product (do not skip any troubleshooting steps even if you feel steps are repeating)

• With the printer turned on, disconnect the power cord from the rear of the printer.
• Unplug the power cord from the wall outlet.
• Wait at least 60 seconds.
• Plug the power cord back into the wall outlet.
• Reconnect the power cord to the printer.
• Turn the printer on. HP recommends plugging the printer directly into a wall outlet.

 Also, try updating the printer's firmware -HP Printers - Updating or Upgrading Printer Firmware  

Hope this helps! Keep me posted for further assistance.
