| 20080260445 | Method of controlling automatic electrostatic media sheet printing - The present disclosure describes a method of automatically controlling feeding and transporting print media sheets through plural electrostatic print engines having seamed photoreceptor belts for duplex printing. In one embodiment the second photoreceptor belt is driven at a variable speed to maintain a constant phase relationship between the respective seams of the belts. The print image magnification on the front side of the printed sheet is matched by varying the speed of the scanner (ROS) in the second engine. In another embodiment. the first and second photoreceptor belts are both driven at a constant speed and the seam phase allowed to float. Sensors provide a timing signal upon passage of the seam in each belt respectively; and, the position of the belt seams thus determined. The system then calculates a release time for each sheet from the feeder to insure the sheet avoids the seam on both belts. | 10-23-2008 |

| 20080266592 | Scheduling system - Described herein is a printing system comprising a plurality of print processing modules which selectively transfer print media therebetween during printing and a system controller that tracks process control protocols of each of the plurality of modules and compares to a scheduled job run and selectively alters a control variable of at least one of the process control protocols thereby preemptively altering initiation of at least one process control protocol to process the job run uninterrupted. | 10-30-2008 |
| 20090326863 | SYSTEM AND METHOD FOR SENSOR PHASING USING A SUBSTRATE EDGE SIGNAL - A system and method for measuring a substrate edge signal for image sensor phasing. An intermediate transfer substrate edge signal can be effectively mapped by a substrate edge sensor and recorded for at least one complete revolution. A substrate edge signal from an inter-document zone sampled from any region of a substrate in runtime by a process sensor can also be recorded. A comparison or cross-correlation can be applied between the bare intermediate transfer substrate edge signal and the substrate edge signal sensed in the inter-document zone. A cross-correlation algorithm returns a maximum peak value when the two signals are registered in-phase with one another. This information can then be used to register the bare belt process sensor signal and the process sensor signal over the region of interest in-phase with one another. A flat-fielding algorithm can also be applied to the phase-aligned process sensor data to remove artifacts and compensate for substrate (e.g., belt) induced non-uniformities. | 12-31-2009 |
