Abstract: Printers are provided. In one aspect, a printer controller causes a sheet delivery system, the receiver delivery system and the receiver transport system to position a receiver and a sheet in a receiver transport path for travel through a printing area with a cross edge positioned on the sheet to separate a portion of the sheet that is masked from toner transfer from an unmasked portion of the sheet. The printer controller further causes the receiver and the sheet to be moved through the printing area so that the cross edge is moved through printing area during transfer of a toner of the print image. The unmasked portion of the sheet is positioned to receive any portion of the print image that is transferred when the receiver is not in the printing area.

Abstract: In methods for operating a printer a sheet is provided in a printing path leading to a printing area, a receiver is provided having a cross edge to which a printed image is to extend in the printing path for movement with the sheet. The receiver and the sheet are moved through the printing area so that the cross edge is moved through printing area during transfer of a toner to form the print image. The receiver and the sheet are further moved through the printing area with the cross edge of positioned on the sheet to separate a portion of the sheet that is masked from transfer of the print image from an unmasked portion of the sheet and the unmasked portion of the sheet is positioned to receive any portion of the print image that is transferred when the receiver is not in the printing area.

Abstract: A method for operating a printing module includes determining that a receiver is to be printed having an image that extends to a cross edge of a receiver that is positioned across a printing path along which the receiver is moved during printing, determining when the receiver is at a position relative to a printing area where a print image can be formed on the receiver; and, printing a toner image so that the print image is being printed when the cross edge of the receiver is positioned in the printing area. Prior to printing, the cross edge of the receiver is positioned on a sheet to divide the sheet into a receiver masked portion and an unmasked portion and wherein the toner image is printed so that printing of the toner image occurs only when one of the sheet and the receiver are positioned to receive the toner image.

Abstract: A duplex document handler feeds document sheets from a document sheet supply to a stationary exposure position through which the document sheets are moved for scanning by a linear CCD array. Duplex document sheets are fed from the exposure station into a loop, leading edge first, and returned, still leading edge first, to the exposure for exposure of the opposite side of the sheet. The document sheets are moved in opposite directions through the exposure station for exposure of the two sides. The loop is the size to receive either one large, for example, ledger sized document, or two smaller, for example, letter or legal sized document sheets, before receipt of further document sheets.

The supply hopper comprises a tray for supporting a stack of fanfold paper, the tray including a base member oriented at an angle in the range of between 25.degree.-45.degree. from the horizontal. A stop member is connected to the base member along the lower marginal edge thereof, the stop member and the base member forming an included angle of substantially 90.degree.. Further, a guide member is supported by the tray substantially above a fanfold paper stack supported on the tray at a height sufficient to lift the topmost individual panel of the stack at least partially off the stack when the fanfold paper is threaded over the guide member. A bail assembly is connected to the tray extending away from the base member of the tray on the opposite side of the stop member from the base member.
