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.

Abstract: The present invention is directed toward a flexible plastic platen used as a document support surface in a copying/printing machine. The platen, in a preferred embodiment, is an optically clear polycarbonate sheet, inexpensive and easy to handle. The platen is mounted in a machine frame so as to be slightly flexed upward along a width area corresponding to the area to be scan-illuminated to ensure accurate focusing of the document image through an underlying linear lens array. The platen is easily replaced by releasing the tension and lifting the platen out of a seated position.
