Hi @Teresa0205,
Welcome to the HP Support Community.
I'd be happy to help you!
I understand that you are having issues with the error E.
1) Take out the cartridges.
2) Unplug the power cord from the printer & wall.
3) Wait for 30 seconds.
4) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not into a surge protector.
5) Insert the cartridges back into the printer.
Remove the cartridges > Unplug the power cord > Wait for 30 seconds > Plug the power cord back > Insert the cartridges
