Firstly check that the input voltage is correct for your area. Seems to cause a number of issues.

After checking the voltage, as suggested above, also go around and check each connector. Unplug them, make sure all pins are 100% straight; make sure the wires going into each connector are totally inserted. I’ve found that some connectors were not put together very well (poor quality control) so they could be squashed or otherwise not making contact.

If you do have the voltage set right and this freakout is still happening, then please try the above.

If you are comfortable with electronics, you might consider taking off the bottom cover, with the printer unplugged from the mains, of course, and checking all the connectors and wires in there.

I highly suspect something is disconnected.

Hope that helps.
