Abstract
In a toner cartridge, photoconductor drum (11) is driven by a gear (3) which is in the printer, toner adder roller (48) is driven independently by a face coupling (5) which is in the printer. On the opposite side, a gear train from toner adder roller (48) drives developer roller (42) and toner paddle (52). The two systems permit the cartridge to function in different printers requiring different ratios of speeds. Stiffness requirements of the cartridge are reduced. Movements are more consistent, and space utilization is enhanced.
