Abstract

The present disclosure describes location of a dedicated purge sheet destination at the terminus of the paper path in a reprographic or printing machine. A dedicated purge sheet destination is defined to be a sheet delivery point (e.g., an output tray, a stacker) that is used only for purge sheets; this destination would not be one of the operator selectable job destinations. Placing the purge destination at the paper path terminus permits sheets at any point in the paper path to be sent to the purge destination. In other words, no sheet in the paper path is ever beyond the purge destination.

DEDICATED PRINTER PURGE Proposed Classification DESTINATION U.S. C1.355/314 Michael E. Farrell Int. Cl. G03g 21/00

The present disclosure describes location of a dedicated purge sheet destination at the terminus of the paper path in a reprographic or printing machine. A dedicated purge sheet destination is defined to be a sheet delivery point (e.g., an output tray, a stacker) that is used only for purge sheets; this destination would not be one of the operator selectable job destinations. Placing the purge destination at the paper path terminus permits sheets at any point in the paper path to be sent to the purge destination. In other words, no sheet in the paper path is ever beyond the purge destination.

A dedicated purge destination offers improved throughput by eliminating the need to cycle-down in order to prevent the mixing of purge sheets into a stack of good or usable sheets. When running a job to a shared purge destination, many existing products typically cycle-down and require the operator to empty the job destination in order to continue the job. Here, operator productivity would be improved by eliminating the need to empty the shared purge destination and/or discard the purge sheets placed on the top of the copy stack.
