Abstract

A toner cartridge (1) contains a photoconductive drum (43) having a central shaft (47). The shaft extends outward from the sides of the cartridge so that it can be lowered on a V-shaped locator (301) in the printer. An assembly of a hopper (61), toner adder roller (45) and developer roller (43) is attached to an assembly carrying the photoconductive drum through springs (132a, 132b). The hopper assembly has center locating surfaces (29a, 29b) to receive a downward pressing member from the printer and flat ledges (161a, 133a) to contact rollers in the printer, which permits adjustment of the contact between the drum and the developer roller while positively locating the drum. The cover assembly also has flat locating surfaces (449, 451) near the hopper to rest on the printer frame.
