Abstract: A versatile paper feeding device of an image forming apparatus includes a pick-up roller, a paper support tray under the pick-up roller to stack paper on, a paper support expansion tray to be able to freely slide toward or away from the paper support tray to support the trailing edge of the paper, a forward positioned paper alignment guide on the paper support tray to align a leading end portion of the paper, and a second paper alignment member formed on the paper support expansion tray to align a following end portion of the paper. When the versatile paper feeding device is used to print images on paper of various sizes, the paper can be properly positioned and straightly fed without skewing.
Abstract: A part of the insertion platform 3′ to send the sheets in which the image receiving sheet on which the image is formed, and the transfer sheet onto which the image is to be transferred, are superimposed, to the heat roller pair to heat and press the sheets, in the image transfer apparatus is structured by the member 2G having a function to transmit the light from the lower side. The light transmission function member is any one of a transparent portion, translucent portion, light diffusion portion, or opening portion, and the light source 2L is arranged on its lower side.
Abstract: A printer having a media transport mechanism defining a media path. The path extends from a media supply past a print engine. A media alignment element moves between an extended position intersecting the path between the supply and the engine, and a retracted position away from the path. The printer may include a pair of rollers between the supply and the alignment element and encompassing the path, so that the sheet may be gripped by the rollers at a position adjacent the alignment to preserve the alignment by the element. The rollers may retract the sheet from the alignment element, which may move aside from the media path, so that the media may be fed toward a print engine.
