ABSTRACT:
A dual mode raster input scanner to scan either or both sides of a moving document advancing along a paper path through a scanning station in a first mode, and to scan one side of a stationary document on a scanning platen in a second mode. A scanning station, for scanning in a first mode, includes two scanning elements supported closely adjacent each other and on either side of the document path for scanning substantially simultaneously both sides of a document. A scanning platen supports a document for scanning in a second mode. One of the scanning elements is supported in a scanning position closely adjacent the other scanning element during said first mode and for scanning movement past said scanning platen in said second mode. A single sheet document input is also provided for the supply of single sheets or computer fanfold webs.
