There is a gear that breaks inside the sub hopper. Not a fun job to do. Easier to swap out the whole toner holder unit / hopper from a parts machine. If just buying parts to rebuild make sure parts are still available since this was deemed "end of life" a few yrs back.

If drum is OK let's say 50k and developer depleted you CAN just replace developer. :cool:
