摘要： A roll-fusing assembly for printing upon continuous length print stock of substantially different widths and thicknesses includes structure for compensating for differences in thermal expansion across the pressure roller when engaging differing print stock widths. In a preferred embodiment this includes stepped pressure roller sections of reduced diameters and a contacting heat transfer roller for normalizing surface temperatures across the width of the pressure roller. The disclosed method involves normalizing surface temperatures across the pressure roller to compensate for the differences in thermal expansion that will occur about the pressure roller exterior directly exposed to the heated fusing roller when handling relatively narrow continuous length print stock or stock of differing thicknesses.

摘要： An electrophotographic printer 10 is described having a print justification control for controlling the justification of the print should the linear speed of the print media 12 passing through the printer 10 be out of synchronization with the rotation of the photo conductive drum 40. The printer has a scan sensor 82 for scanning each scan line. A processor 90 compares the number of actual scan lines to a desired number of scan lines for each print media segment. A print moving sensor is provided to generate a signal for each movement of a print segment of the media. A comparison is made by the processor 90 to determine the number of actual image information scan lines placed in each media segment and for duplicating scan lines should the number of actual scan lines exceed a preset number. If the linear speed of the print media is greater than the circumferential speed of the electro conductive drum, then a processor 90 deletes scan lines.The printer 10 includes a print control system 86 that has an all-white scan line sensor circuit 112 that senses the presence of an all-white image information scan line. This information is provided to the processor 90 to duplicate such an all-white scan line if an out-of-phase condition occurs. If an all-white scan line cannot be found, then the processor 90 selects a particular scan line location for duplication or for deletion or proceeds through a random selection algorithm for selecting such lines for duplication or deletion.
