Apparatus and method of controlling insertion of substrates into a stream of imaged substrates

摘要

An apparatus and method is provided for controlling the insertion of one or more special insert sheets into a steam of regular imaged sheets. A coded sheet is placed into a sheet stack in a position where an insert sheet is to be placed. Sheets are removed from the stack one by one and transported along a path past a sensor toward a finishing apparatus. When the sensor detects a coded sheet, the coded sheet is diverted from the stream and later replaced with an insert sheet.
