  • Patent number: 7003244
    Abstract: A printer has a cover which includes a jam removal lever position checking portion, a toner container locking lever position checking portion, a shutter switch, and a side cover bracket. The jam removal lever position checking portion interferes with a jam removal lever installed in the main body to check whether the jam removal lever is properly positioned. The toner container locking lever position checking portion interferes with a toner container locking lever installed in the main body to check whether a toner container is properly fixed. The shutter switch opens and closes a shutter to control a flow of remaining toner collected by a developer roller after being developed, into the toner container. The side cover bracket interferes with a side cover bracket installed at the main body to control joining a side cover with the main body.

Since the cover includes members having several functions, parts added when the members are independently installed are not required.
