Have a Fault Error 072-210 and drawer 2 is not operational (doesn't seem to be clicking in, won't register that it has been pulled out and put back in). I can still print from my Windows 10 computer - if I designated Tray (won't print if I leave it at default). Any ideas?
It is physical damage to the tray in my experience.
If you have 3-4 trays, swap tray 2 and 3 in the printer.
If the fault changes to the other tray, take them both back out and compare the parts/sensors etc. One (the one in slot 3) is broken.
If the fault doesn't follow the tray, something in the rails/sensors for tray 2 inside the machine is the fault.
