I have an HP 6400 all in one printer that I was trying to use to scan but it wasn't working. All of the lights were flashing in different colors and I thought it was stuck so tried to cancel the scan. When that didn't work, force quit the scan program on the computer but the lights on the printer kept flashing so I unplugged it. Plugging it back in led to the lights flashing again the same way. Then I tried to reset to factory settings and now the rainbow lights have stopped but I can't connect to wifi with the printer and it keeps flashing E and 0 over and over. I can't figure out if I was successful in restoring the factory settings and it needs to be reset or if I just messed something up.
