Something to do with the hardware of your printer.
Make sure the printer is connected directly to the walljack without a surge protector and then try to scan and if this does not work.
pull out the power cable without shutting the printer down.
then pull out the printer power cable from the wall socket.
Wait for a minute and then connect the printer power cable to the wall jack and then connect it to your printer and this should resolve your issue
