Abstract
A technique is provided for controlling the interposition of one or more special sheets into a stream of regular imaged substrates. In one example, a point in time at which a special insert sheet should be fed from a special insertion sheet subsystem to the stream is determined by reference to plural sets of preset time periods. In this example, the preset time periods can be adjusted to accommodate print engine/interposing module machine clock fluctuations. In another example, interposition of a special insert sheet with the stream of regular imaged substrates is maintained at an acceptable level by comparing a distance between a special insert sheet fed to the stream and an adjacent regular imaged substrate with a predefined tolerance. The comparison can then be used to adjust feed times of special insert sheets subsequently fed to the stream.
