Abstract

A copying system 1 for both simplex and duplex copying of a document original, The system 1 employs conventional cleaning 2, charging 3, imaging 4, developing 5 and copy feed 6 stations, as well as a conventional photoreceptor belt 7. The path of copy sheet travel can be varied depending on whether simplex (one side) or single pass duplex (two side) copying of the document is desired.

A copying system 1 for both simplex and duplex copying of a document original, The system 1 employs conventional cleaning 2, charging 3, imaging 4, developing 5 and copy feed 6 stations, as well as a conventional photoreceptor belt 7. The path of copy sheet travel can be varied depending on whether simplex (one side) or single pass duplex (two side) copying of the document is desired.

In simplex copying, the document image is transferred at a first transfer station 8, then the copy is stripped from the belt 7 and carried by a simplex transport 9 directly to an image fuser 10. In duplex copying, the document is also stripped from the photoreceptor 7 after passing the first transfer station 8 but is then acquired and inverted by a separate vacuum transport/duplex inverter 11 rather than going to the simplex transport 9. Once the document is inverted, it is again transported to the photoreceptor 7 which carries it through a second transfer station 12 to the fuser 10. The simplex transport 9 avoids copy sheet recontact with the photoreceptor and bypasses the second transfer station 12.
