ABSTRACT:
A reproducing machine has a rotatable toner supply cartridge which dispenses toner into a developer sump, the cartridge being inclined at an angle with respect to the horizontal axis so as to dispense toner assisted by gravity, in controlled amounts only from a dispense port at the end of the cartridge extending below the horizontal. The supply cartridge is modified by the addition of an end cap assembly which incorporates a scoop member which picks up and stores a quantity of toner during rotation. A cog wheel is mounted on the outside of the end cap assembly and is attached to a shaft extending through the end cap assembly. The cog wheel interacts with stepping pins to enable a dispense operation from the scoop member.
