Just set up a new printer. It is working fine but right now it isn’t in use and it is making a really annoying low humming sound. For most people it would probably be unnoticeable but I have very sensitive ears. It sounds as if an alarm were going off somewhere in the distance. There’s no error messages or any kind of paper jam or other issue that I can think of. 

printer is on quiet mode.
