Abstract

An "S" shaped path for a recirculating document handler (RDH) for use in paper and related document handling systems, particularly in electrophotographic copiers and duplicators, is disclosed. This configuration overcomes some of the shortcomings of existing RDH configurations and relies on a sheet being turned over an odd number of times. It becomes inverted and the reverse side may be imaged.

"S" RDH(cont'd)

An "S" shaped path for a recirculating document handler (RDH) for use in paper and related document handling systems, particularly in electrophotographic copiers and duplicators, is disclosed. This configuration overcomes some of the shortcomings of existing RDH configurations and relies on a sheet being turned over an odd number of times. It becomes inverted and the reverse side may be imaged.

As shown in Figure 1, in a first step an original document 1 with side 1 face up (indicated with x's) is transported from a feed tray 7 to a platen 2 via the input path 4, for imaging. After imaging, the document reverses and returns past the gravity gate 5 to feeder tray along path 3 and undergoes two additional inversions. The document underwent one inversion while going onto the platen and two inversions while returning from the platen, and is inverted from its original orientation in the feeder tray.

In a second step, as shown in Figure 2, duplex mode may be continued when the original document is transported via path 4 back to the platen to image the second side (reverse side). The original can be returned to the stack via path 6 restacking side 1 face down, or via path 4 for restacking side 1 face...
