Abstract
An apparatus and method which provides job integrity and security for each sheet transported to and from a printing station including periods when a printing machine has cycled down enabling an operator to remove sheets therefrom. Each sheet transported to the printing station and each sheet delivered from the printing station is counted. A controller compares the number of sheets transported to the printing station to the number of sheets delivered from the printing station and the number of any sheets that may have been removed by the operator from the printing machine as a result of a cycle down. Operation of the printing machine will be inhibited if the number of sheets transported to the printing station do not equal the number of sheets delivered from the printing station and the number of sheets removed by the operator. Conversely, operation of the printing machine will be enabled if the number of sheets transported to the printing station does not equal the number of sheets delivered from the printing station and the number of sheets removed by the operator.
