    摘要: An additive fabrication apparatus with an efficient reversal mechanism to reverse the orientation of foil guiding rollers is contemplated. To this end, according to an aspect, a foil guiding system comprising: a flexible foil guiding roller; and a bearing system arranged to bear said guiding roller, said bearing system comprised of end locking elements axially locking to the roller; a bearing arrangement defining a bearing position having the roller curved in bearing engagement. The bearing arrangement engages with an outer face of said roller in a manner so as to thereby flex the roller between at least two bearing positions in conformity with a rolling direction. The flexible roller in connection with the outside bearings replaces a fixed shaft arrangement of the prior art, which is easily tunable to the foil movement direction.

    摘要: A scanner and a method of scanning an image on an original includes an optical sensor having sensor elements for each of three basic colors that is used to generate pixel values of the scanned image. Each pixel value represents an optical density of a pixel of the image and is generated mainly on the basis of a signal of only one of the sensor elements. Each of the sensor elements for each of the basic colors is used to generate pixel values representing substantially different parts of the image.
