Abstract
A raster input scanner, and a reproduction system that uses that input scanner, having multiple depths of focus. The raster input scanner includes a light source for emitting light toward an image bearing member and at least two lens arrays, with the ability to selectably position any one lens array in optical conjugate relationship between the image bearing member on a transparent platen and a photosensor array. One of the lens arrays has a first depth of focus, while the other lens array has a second depth of focus that is different than the first depth of focus. Beneficially, the input scanner responds to an operator selection of which depth of focus is to be used to image a given image bearing member.
