Abstract: The method or system for controlling a printing or copying system for processing single sheets, a first single sheet and at least a second single sheet immediately following the first single sheet is processed with aid of n processing units. A required minimum distance between the first and the second single sheet is determined for each processing unit. A delay distance is determined for the first and at least for each of the n?1 following processing units. A difference between the minimum distance of a processing unit and a sum of the delay distances of the preceding processing units is formed. A smallest possible distance with which the second single sheet is fed to the first processing unit after the first single sheet is determined by a highest value of the determined minimum distance of the first processing unit and the determined differences.

Further provided is a displacement preventing system that prevents a displacement of the continuous form paper in a feeding direction of the continuous form paper when the tension applying unit operates to apply the tension to the continuous form paper.

Abstract: A device and method for applying images to continuous media stock, such as rolls of paper, blank labels, etc., using a cut-sheet image forming device. While the continuous media stock moves along a media path in the cut-sheet image forming device, one or more sensors in the cut-sheet image forming device detect inter-sheet holes disposed along the continuous media stock. Based on the detected inter-sheet holes, the cut-sheet image forming device tracks the position of the continuous media stock. By tracking the position of the continuous media stock, the cut-sheet image forming device can identify specific sections of the continuous media stock as image areas appropriate for image transfer.

Abstract: When a roll paper unit 200 is incorporated into an image formation apparatus, a second outlet guide member 92 is turned around a pivot 92a in the direction of an arrow G, i.e., moved from a position of solid lines to a position of two-dot chain lines, a rear end portion 92b of this second outlet guide member 92 pressing down a front end portion 80c of a guide member 80 to cause the guide member 80 to be turned around a central shaft 80d in the direction of an arrow H, i.e., moved from a position of solid lines to a position of two-dot chain line. Consequently, a path extending in the direction of an arrow C is closed, while a path extending in the direction of an arrow F is opened, the roll paper 72 being transferred in the paper feed direction. When the roll paper unit 200 is drawn out, the second outlet guide member 92 and the guide member 80 are turned in the directions opposite to those mentioned above.

Abstract: In the case that recording paper of a roll (20) has run out during an image forming process, when the length of a piece of the remaining recording paper left last is longer than the first reference length possible to feed the paper in the inside and outside of a roll unit (RU), the paper is delivered, and when the length of the remaining piece is slightly shorter than the first reference length, the front end of the remaining piece is projected to the outside of the roll unit (RU), and when the length of the remaining piece is shorter than the second reference length impossible to feed the paper in the inside of the roll unit (RU), the remaining piece is dropped inside of the roll unit (RU) by a reverse feeding, thereby, a removal of the remaining piece is facilitated. Thus, the removal of the remaining piece may always be performed well.

Abstract: A continuous web substrate printing system which can utilize a single otherwise conventional or existing xerographic print engine (normally printing conventional cut sheet print substrates) having an endless photoreceptor belt with a belt seam requiring a section of that belt to be unimaged in each belt rotation, yet provide continuous directly abutting images on the printed web, to avoid paper scrap. A special simplex or duplex continuous web printing substrate supply module may be docked with the cut sheet print engine to form an integral web printing system. It has a web feeding and image transfer system for appropriately feeding the continuous web printing substrate uncut into the print engine for image transfers to one or both sides of the web from the imaging surface of the print engine.

Abstract: A terminal (1) for wirebound telecommunication according to the invention comprises a class D amplifier which is supplied with a rectified ringing voltage (V.sub.ring) coming from the line (2) in a ringing condition and, in an off-hook condition, is supplied with the line voltage (V.sub.ln) coming from the line (2). A class D amplifier (20) is advantageous in that it is suitable for use with supply voltages which may vary over a large range. As a result, both the rectified ringing voltage (V.sub.ring) and the line voltage (V.sub.ln) can plainly be used as a supply voltage for the amplifier (20) and no additional circuits are necessary for matching these voltages.

Abstract: An image forming apparatus capable of cutting a strip-shaped continuous sheet on which an image is formed to a desirable cutting length. A rolled-sheet is conveyed by registration rollers and the like. The rolled-sheet is further led to the vicinity of a photosensitive drum through pre-transfer rollers. The rolled-sheet to which a toner image has been transferred is subjected to toner fixing processing by a fixing device. When the leading end of the rolled-sheet reaches the pre-transfer rollers, the rotational speed of a sheet feeding motor is increased during a predetermined time. Consequently, the sheet conveying speed on the upstream side of the pre-transfer rollers in a direction of sheet conveyance is increased, thereby forming slack in a sheet portion between the registration rollers and the pre-transfer rollers. Consequently, tension exerted on a sheet portion between the fixing device and the pre-transfer rollers does not affect the conveyance of the sheet by the registration rollers.
