Abstract: For the reproduction of originals, images are generated on an image carrier, for example by printing. The imaging device that generates the image is usually not capable to cover at once the complete image area on the carrier. If the device is capable to cover the full width of the image area, the image may be generated line by line. Devices not having this capability will generate a first portion of an image line on the carrier. An adjacent second portion of the image line is then generated by another imaging device or after a period of time by the imaging device that generated the first portion. The region where the first and second portion meet on the carrier may cause visual artefacts on the final reproduction due to spatial misregistration of the adjacent line portions. This problem is solved by dividing the image in adjacent sub-images having an overlap zone on the carrier.

Abstract: A guide method and apparatus is provided for use in an imaging system in which media is moved through the system in a first direction. The guide apparatus includes a roller unit for contacting a surface of the media and maintains contact with the surface of the media as the media moves in the first direction, and a retraction unit for separating the roller unit from the media. In an embodiment, the guide apparatus includes a carriage that moves radially toward and away from an internal drum so that the leading portion of media may be held against the internal drum. In other embodiments the guide apparatus includes a carriage that moves along the inner surface of an internal drum together with the leading portion of media. The method guides media in an imaging system in which media having a curled leading edge is moved through the system in a first direction along an inner surface of a cylindrical drum.
