There is an issue with tray 5 on printer 2-2. The lift motor is failing and the only way around it for now is to not load any paper into it (the printer will re-route and print from other trays if it is left empty). However, if paper is loaded, or even if someone loads paper in the other trays, it loses its mind. So if it is stuck on a screen with an error code, it will run properly on a reboot (it’s just the process it goes through after filling the paper throws the error code).
TL/DR: Leave tray 5 empty!
