摘要： A system for cooling a developer roll inside an image forming device. In one embodiment of the invention, the system for cooling the developer roll includes an air duct for carrying an airflow, the air duct having at least one opening to allow airflow to pass therethrough, and at least one toner cartridge in fluid communication with the air duct. The at least one toner cartridge includes the developer roll and at least one input port. The at least one input port is coupled to the at least one opening of the air duct to receive the airflow and to direct the received airflow towards end portions of the developer roll via a conduit and nozzles located within the toner cartridge. The system provides an effective way for introducing the airflow into the toner cartridge for cooling the developer roll.

摘要： Toner is conserved in an image forming apparatus, such as an electrophotographic printer (e.g., laser printer), by varying the interpage gap when approaching an exhaustion of the recording media supply (“paper out”). A supply level sensor is used to determine whether the supply of discrete recording media (e.g., paper sheets) is above or below a predetermined level. A smaller value interpage gap is used when the supply level is above the predetermined level. The interpage gap is automatically lengthened to a second larger value when the sensed media supply level drops below the predetermined level. The longer second interpage gap allows for “paper out condition” that may result from printing of sheet N−1 to be determined prior to image formation beginning for sheet N. The interpage gap may be reset to the smaller value when the supply has been refilled to above the pre-determined level.
