Abstract: Processes from the scanning of a document in a preset scan mode to a process executed for the scanned image are set as scan jobs. When an icon associated with the scan job is selected, the scan job is executed. Thereby, the processes from the scanning of the document to the process executed for the scanned image can be automatically executed by selecting the associated icons, and the user operations are simplified and made easier.

Abstract: A paper feeding apparatus for use in a printer includes a sheet feeding path between a sheet feeding section and a developing section, a sheet ejecting path disposed such that a sheet on which an image is printed at the developing section is fed via a fixing section, an ejecting roller, and a reversing path to feed a sheet diverging from the ejecting path to the sheet feeding path again. The apparatus further includes a reversing tray disposed between the ejecting path and the reversing path to reverse the fed sheet, and a guide member rotatably mounted between the ejecting path and the reversing tray, to direct the sheet to the ejecting path or to the reversing tray.

Abstract: A double-sided image forming device comprises a double-side operation unit. The double-side operation unit includes a sheet reversing unit including a switchback conveying path for reversing a front side and a back side of a sheet conveyed from an image forming unit, and a reconveying path for reconveying the sheet to the image forming unit so as to form an image on the back side. The switchback conveying path has a length smaller than a length of a conveyable maximum-size sheet. The double-side operation unit can slide from/toward a body of the double-sided image forming device in a direction perpendicular to a direction of conveying the sheet. A rear end guide is further provided in the switchback conveying path so as to guide a rear end of a large-size sheet.

Abstract: A host device successively sends print data constituting a plurality of sets of copies of a document to be printed to a printer capable of printing on both sides of printing paper. If each set of copies to be printed consists of an odd number of pages, a blank page is inserted as the reverse side of the last page to make the total number of pages of the set of copies an even number. The print data thus created is sent to the printer as a single job. This makes it possible to prevent the last page of one set of copies and the first page of another set of copies from being printed on the same sheet of paper, thereby allowing each set of copies to be printed as a discrete set independent of other sets. Print job management is performed on the basis of a single print job.

Abstract: A device and method of printing data in multiple copies in a collated or uncollated copy mode. A number of print copies, desired, is set and the data is converted to a predetermined format suitable for printing. The converted data is stored in a storage unit when the copy mode is the collated copy mode or directly printed when the copy mode is the uncollated copy mode.

Abstract: An image forming apparatus has a double-sided image forming mode. In this mode, a paper sheet is fed to a printer section to form an image on its first side and reversed through a reversing path of a reversing mechanism. The reversed paper sheet is stacked temporarily in a temporary stacking section and fed again to the printer section by a pickup roller to form an image on its second side. The paper sheet is then ejected. If there are no sufficient paper sheets in the stacking section before the double-sided image forming mode is completed, it is determined that an accident has occurred and the double-sided image forming mode is executed again. If a paper sheet remains in the stacking section after the double-sided image forming mode is completed, it is also determined that an accident has occurred and the double-sided image forming mode is executed again.

Abstract: An image forming apparatus operable in a duplex image transfer mode of the present invention stores image data to be transferred and transfers the image data to a recording medium at an image forming section. In the duplex image transfer mode, a reversing section reverses a paper sheet or similar recording medium passed the image forming section and again delivers it to the image forming section. When image data does not have to be transferred to the rear side of the last paper sheet, the last paper sheet carrying an image on its front side is driven out of the apparatus from the halfway point of a reversal path via an outlet path without the intermediary of the image forming section. The apparatus successfully reduces the conveying time.

The simple gear linkage provides a fixed rotational relationship between the drive roller and a feed roller of the simplex handling apparatus. A media guide pivots about the drive roller's axle between a first position into which it is biased, and a second position into which it is deflected by a media sheet. From the first position, a media sheet retracting from a print zone can enter the duplex media handling system. From the second position, a media sheet can move from the input tray around the feed roller into the print zone, or move out of the duplex media handling system back into the input tray to await refeeding for second side printing.
