Abstract
A system and method are provided for improving stack integrity for a set of image receiving media substrates at an output of a compiler in an image forming device by positioning a particularly configured substrate handling device downstream of the output of the compiler in a process direction. The substrate handling device is configured of a plurality of omni-directional wheeled devices that provide drive (traction) normal to a motor axis under control of one of a respective plurality of independent motors while allowing sliding in the motor axis direction. The omni-directional wheeled devices, in one embodiment, are configured with small roller wheels along the periphery of the wheel. When using three or more omni-directional wheeled devices, translational movement can be combined with rotation to deliver sheets of image receiving media exiting the compiler at a correct angle and lateral position for further processing.
