I would advise you to first unplug the printer instead of turning it Off, when it is On to begin with.
Then with it unplugged from the power, open it up and examine the entirety of the paper path, the path paper travels through the printer.
Blow out any dust or paper fluff that might be lingering there. (But not violently nor with 'canned air' - you might blow dust up into the printhead and the inking system, not affecting it very well and possibly leading to errors from a clogged printhead.)
Make sure there is no debris inside the printer, no paper scraps, no loose parts littering the paper path, etc.
Check the rear paper path area, or the 'duplex' if there is one, also. The rear hatch at least, that is, needs opening and inspecting for anything like dust, fluff, or paper or scraps.
Then after 10 minutes or longer subsequent to unplugging the printer to turn it Off, plug it in again, and turn it On if it doesn't turn On by itself.
See if that clears the error - if not, Reply To Expert and tell me, and mention how old the printer is, and whether the printer is plugged into a surge protector.
