I have just replaced my printer ink cartridges on my HP 6978 and I keep getting error message that says there is a Carrige Jam. I have checked and there is no jam of any sort. I have tried doing a hard reset of unplugging the printer, removing the power supply and hitting the power button for 30 seconds and I am still getting an error message. I am also getting an error message everytime I turn on the printer saying that the printer was not properly shut down even though I used the power button to turn off the printer and wait for it to power down before unplugging. Additonally I have tried doing a factory reset and that is not working as my settings and wifi are still present.
