摘要： A transfer blade apparatus for ironing a sheet against the photoreceptor belt during transfer, and smoothing out deformities which cause deletions is disclosed. The transfer blades include a flexible tip to absorb the impact of the blade as it contacts paper, and a spring load to limit and control the force applied to the sheet. Sensors are also utilized to monitor and adjust the timing of the blades.

摘要： An apparatus which advances a sheet through a transfer zone and into registration with information developed on a moving member. The sheet is advanced to a position wherein a leading portion thereof is immediately ahead of the transfer zone relative to the forward direction of movement of the moving member and a trailing portion thereof is within the transfer zone. The leading portion of the sheet forms a presentation angle of 7-10 degrees with the horizontal. The trailing portion of the sheet is advanced through the transfer zone at a first velocity and the leading edge of the sheet is advanced in a region immediately ahead of the transfer zone at a second velocity, which is less than the first velocity, so as to create a buckle in the leading portion of the sheet positioned immediately ahead of the transfer zone relative to the forward direction of movement of the moving member. The buckle functions to eliminate relative velocity between the photoconductive belt and any portion of sheet within the transfer zone so as to substantially eliminate slip between the sheet and the photoconductive belt.

摘要： A sheet feeding and corrugating system, especially for output of image substrate sheets of a reproduction apparatus, wherein the sheets are fed in a normal path through a sheet feeding nip comprising plural spaced sheet feeding rollers. Both feeding and variable corrugating of flimsy or stiff sheets is provided by spherical balls freely mounted in generally vertical ball retainers providing for vertical movement and dual axis rotation against the sheet feeding rollers to define the sheet feeding nip and by additional similar balls (in additional similar ball retainers) intermediately of the feed rollers, which additional balls are unsupported vertically except by bottom-of-travel retainers so that these additional intermediate balls roll gravity-loaded against a sheet being fed through the nip to provide sheet corrugation varying automatically with the stiffness of the sheet, and are freely liftable up to the level of the nip by stiff sheets resisting corrugation. These balls may be readily added to or removed to independently increase or decrease the sheet nip and/or corrugation forces at their respective locations transverse the nip. A sheet side shifting mechanism can laterally offset the sheets in the same nip to eject offset, by moving only the sheet feeding rollers, without resistance from the stationarily mounted balls, all of which roll freely laterally as well in the normal feeding direction.

摘要： A low-cost finisher that creates stapled books includes a tray that is tilted at an acute angle backward and away from the direction of incoming copy sheets. Copy sheets are fed into and slide down the copy sheet support surface of the tray and against a rear registration wall of the tray under the influence of tampers. Another tamper forces the copy sheets against a side registration guide of the tray to align them in the head of a stapler. Stapled books are transported out of the tray to a catch tray.

The stalled sheet folding and flattening apparatus includes a fixed component of the sheet handling system connected to a frame of the machine and having a first section of a sheet path; a withdrawable component of the sheet handling system mounted to the frame, and having a sheet flattening side defining a relatively narrow gap between a fixed surface within the machine and the withdrawable component, and including a second section of the sheet path adjoining the first section of the sheet path; and a sheet folding device mounted to the fixed component. The sheet folding device includes a generally U-shaped portion defining a slot and having a sheet contact surface forming a part, of an edge of the first section of the sheet path, for contacting and deflecting into a first fold, an edge of a sheet stalled across an interface between the first and the second sections of the sheet path, when the withdrawable component is being pulled out of the machine. The sheet contact surface of the U-shaped portion has a first radius of curvature defining a first concave surface for deflecting and folding the stalled sheet, and a second radius of curvature defining a second surface for guiding the folded sheet out of the slot.

摘要： A method and apparatus for manipulating the velocity of a copy sheet in a color reprographic system creates a buckle in the copy sheet to decouple accelerations of the leading edge of the copy sheet from the portion that is in contact with the photoreceptor belt and reduces the buckle on long copy sheets for which the buckle can become large enough that the toner image on the body of the copy sheet can become disrupted by contact with stationary portions of the system. The method and apparatus also accelerates the leading edge of the copy sheet as the trailing edge disengages from the photoreceptor belt to prevent the uncontrolled trailing edge of lightweight copy sheets from contacting stationary portions of the system.

摘要： A method and apparatus for detecting and discriminating a copy sheet in an electronic reprographic printing system has a diffuse reflective sensor disposed adjacent a portion of the path over which the copy sheet moves. The sensor is disposed so that its optical axis intersects the copy sheet where the angle of intersection between the copy sheet and the optical axis remains within a specified range of angles for the maximum length of the copy sheet. A diffuse reflective sensor is also disposed adjacent inlet baffles with its optical axis aligned so that a transparent copy sheet is not detected while an opaque copy sheet is.
