Large document copying system

A system for copying large documents on a large document copier having a large document sheet feeder and a large copy sheet or web feeder with improved convenience and efficiency comprising the steps of:

• inserting the leading edge of said large document into said document feeder from the front of said large document copier,
• automatically initially feeding said large document away from the front of said large document copier with said large document feeder,
• pausing said feeding of said large document by said large document feeder in a position wherein a trailing portion of said large document is retained by said document feeder and a substantial portion of said large document is removed from the front of said large document copier so that the front of said large document copier is unobstructed by said large document,
• inserting a copy sheet or web into said large document copier from the front thereof for copying.
• activating said large document copier to copy said large document onto said copy sheet or web after said copy sheet or web has been inserted,
• and, in response to said copying activation, first automatically rapidly feeding said large document back in a reverse direction with said large document feeder with out copying, to a position wherein a leading portion of said large document is retained by said document feeder, and then, promptly thereafter, automatically again reversing the direction of feeding said large document with said large document feeder and moving said large document away from the front of said large document copier at a copying speed synchronized with movement of said copy sheet or web for copying said large document onto said copy sheet or web.
