Existing support for edge sensitive paper

In addition to the requirements for side sensitive paper, many cut-sheet printers also require that edge sensitive paper be loaded differently for simplex and duplex. This is common for printers where the holes are on the leading or trailing edge as the paper moves through the printer. The paper is loaded with the holes either on the leading or trailing edge for simplex and rotated 180 degrees for duplex. This requires either:
  • Manual operator intervention to reload the bin between simplex and duplex jobs.
  • Two bins that are loaded, one for simplex and the other for duplex. The application is coded to select the proper bin.

More sophisticated cut-sheet printers have support for edge sensitive paper. The paper bins have a configuration setting for edge sensitive paper, and the output prints properly for both simplex and duplex. Also, the holes are stacked on the same side in the stacker. However, the output prints by using the duplex paper path for both simplex output and duplex output, which cuts simplex throughput in half.
