Toner cartridge with heat shield shutter |
摘要 |
A toner cartridge (1) has a single molded element, molded of polystyrene, which is heat sensitive. The molded element forms front handles (3a, 3b) and a cleaner chamber (27) mounts a photoconductor drum (49). A toner hopper (61) is located generally under the handles. A developer roller (43) receives toner from the hopper and applies it to the photoconductor drum. A lower shutter (7) of polycarbonate, which is heat resistant, is mounted on actuating links (13a, 13b). When the cartridge is installed in the printer the actuating links are moved to rotate the shutter to a position covering the lower surface of the cleaner chamber, where it serves as an effective heat shield protecting the cleaner from fixing heat of the printer.
