Abstract
A method of automatically positioning a test pattern in the interdocument zone of an imaging surface of a printing machine using a sensor with a given field of view. Once the test pattern has been provided in the interdocument zone of the imaging surface, the timing relationship of the test pattern to a plurality of edges of the sensor field of view is determined. The control then responds to the timing relationships to locate the sensor field of view with respect to the test pattern and determine the time period between creating a test pattern and sensing the test pattern.
