Abstract: An image forming apparatus includes a circulating transfer path for transferring a sheet. The image forming apparatus is capable of forming images on both surfaces of the sheet by: transferring the sheet having an image formed on a first surface thereof along the circulating transfer path; and forming another image on a second surface of the sheet after the transfer. The circulating transfer path is utilized for securing time taken for the sheet having an image formed thereon to dry.

Abstract: System and methods providing a plurality of fusers, and one or more radius profiled media handling transports for transporting media in a radius, in an image forming device. The system includes one or more of a plurality of fusers, and radius profiled media handling transport devices arranged in a fashion allowing for improved throughput of media while reducing operating costs. The plurality of fusers allows for the use of individual low capacity fusers that are equal to or less than the overall capacity of the image forming device. Media transport devices transport media on stretch belts across a radius of rollers with a means for providing an adhering force for stabilizing the media to the belt. The rollers are arranged along one side of the frame, along which the media is transported, and a frame may contain an air plenum so as to allow for the drawing of a vacuum through the rollers. The media transport device allows for optimizing a configuration of the image forming device.

Abstract: A technique in an image forming apparatus in which the front and back sides of a sheet are reversed by using a reversal conveyance path is provided for causing the sheet to wait such that the sheet is not damaged when a unit for conveying the sheet to the reversal conveyance path is pulled out for the purpose of clearing a jam or the like.A roller for conveying the sheet is controlled such that the sheet to be turned back and directed into the reversal conveyance path is caused to wait until the sheet can be conveyed into the reversal conveyance path. As a standby position of the sheet while the sheet is caused to wait, a position is set such that an upstream end portion in the second conveying direction of the sheet to be directed into the reversal conveyance path does not extend for a predetermined length or longer into another conveyance unit adjacent to the intermediate conveyance unit upstream from the intermediate conveyance unit in the second conveying direction.

Abstract: A drive apparatus for driving media sheets in a printing device is disclosed. The drive apparatus includes a fuser drive train, a duplexer drive train, an exit roll gear and a bell crank. The bell crank is at least partially disposed in-between the fuser drive train and the duplexer drive train and is capable of swinging to assume one of a first position and a second position. The bell crank in the first position couples the fuser drive train to the exit roll gear driving the exit roll gear in the first direction for driving a media sheet into an output bin of the printing device. The bell crank in the second position couples the duplexer drive train with the exit roll gear driving the exit roll gear in the second direction for driving the media sheet along a redrive path into the printing device.
