Try disconnecting the keypad, if it's a dodgy key then that should at least let you use the printer via usb while you get a replacement keypad.

If that doesn't work - check all the power connections to the motherboard. one could have worked looses. But sounds more like stuck keypad key to me.
I tried unplugging the screen, but that didn't fix the problem. I tried plugging the printer into my computer via USB, but the following showed up: "Unknown USB Device (Device Descriptor Request Failed) Driver Failure"
I attempted to "find a new driver", but my computer said the best driver is already installed.
