Abstract
A reproduction scanning system having intermediate storage between input and output scanning stations wherein an input document is scanned in first and second directions, the first direction being orthogonal to said second direction, and the electrical signals representative of information on said scanned document being stored on an intermediate storage member for storage, signal processing or data manipulation. The information stored in the storage member may be read out and reproduced on a reproducing medium. Other system features include input scan reversal for alternate bound pages during bound volume scanning, synchronization of the system by a clock associated with the storage member, input/output interleaving with a print interrupt feature, image centering and edge fadeout for image reduction, and independent magnification demagnification by separately variable raster spacing.
