I have a Xerox Colorqube 8570. I used it on Sunday and noticed yesterday it was in sleep mode but sounded like it was running. I did a restart and it will begin the restart process and then the message "Open Ink Loader Door C completely. Press?" is on the screen and seems to be frozen. Nothing happens when I press any button on the control panel. It also still still sounds like it's running. Help?! Thank you in advance!
