Abstract

In electrophotographic printing machines, it is frequently a difficult and messy chore to remove developer material from the developer housing. As shown in Figure 1(A), a cartridge 10 may be positioned in the bottom of developer housing 14. Door 12 pivots in an upwardly direction permitting cartridge 10 to be removed from developer housing 14. Cartridge 10 is shown in more detail in Figure l(B). As depicted thereat, cartridge 10 includes a metal frame 16 having a gasket 18 for securing a plastic or paper bag thereto. A pull tab 20 secured to frame 16 to facilitate removal of cartridge 10 from developer housing 14. In order to initiate dumping, pull tab 22 as seen in Figure 1(C) is pulled in a downwardly direction permitting bag support 24 to flex about notches 26. Bag 28 drops down enabling the material in deverloper housing 14 to be dumped therein. As shown in Figure 1(D), bag 28 is in the open position arranged to receive the developer material within developer housing 14. After the developer material has been dumped into bag 28, cartridge 10 is removed from developer housing 14 permitting a ready disposal of bag 28 with the unwanted developer material contained therein.
