ABSTRACT:
A process cartridge (14) is comprised of a process housing (138) and a transfer housing (148). The process housing (138) contains a photoconductor drum (16) and an intermediate transfer belt (160). The transfer belt (160) is operable to receive multiple images from the photoconductor drum (16) until a composite image is formed on the transfer belt (160). Thereafter, the transfer housing (140) is titled into contact with a backup roller (162) in the process housing (138) through a transfer roller (208). The nip between the two rollers is then operable to feed a piece of paper therethrough and transfer the composite image from the transfer belt (160) to the paper. Alignment pins (114) and (116) on the upper end of the housing and lower alignment pins (118) and (120) on the lower end of the process housing (138) are provided to fit in the guide rails (110) and (112), which provide an alignment function. A driving gear (128) on the end of a motor shaft (132) is operable to drive the photoconductor drum (16) through a gear (126) and subsequently drive all of the processing elements therein.
