Patent number: 7447730Abstract: An image forming apparatus such as a copier and an air conditioner communicate with one another in a network. The air conditioner provides information regarding ambient temperature and/or humidity to the image forming apparatus. Based upon this information, the image forming apparatus selectively activates systems within the apparatus that regulate its internal temperature and humidity levels, to thereby achieve power savings. The image forming apparatus provides information regarding its operation state to the air conditioner. The air conditioner uses this information to adjust its heating or cooling operations to compensate for the heat generated by the image forming apparatus when it is operating.Type: GrantFiled: December 6, 2002Date of Patent: November 4, 2008Assignee: Minolta Co., Ltd.Inventors: Yukinobu Iguchi, Fumio Maekawa
