Abstract: A cleaning system for a fluid ejector arrangement employing a single roller for handling different fluids that should not be mixed. The single roller is divided into portions assigned to respective fluids. In embodiments, the single roller is used to clean a plurality of ejectors, in which case each section of the roller handles one ejector. In other embodiments, the single roller is used to clean a single ejector that ejects to a plurality of fluids, in which case each section of the roller handles one fluid. Still other embodiments can employ a plurality of ejectors and a plurality of fluids ejected from one or more of the ejectors, wherein each section of the roller is assigned to a particular fluid, whether the fluid be ejected from the same ejector or from a different ejector.

Abstract: A printer paper tray improper loading protection system which is automatically moved by the repositioning of a conventional repositionable stack edge guide to restrict improper loading of sheets into the area of the tray which is outside of the proper sheet stacking area for sheet feeding, even though that restricted area varies depending on the selected size of the sheets being properly loaded within the proper sheet stacking area. A customer warning and partial obstruction of the non-feeding restricted area of the tray eliminates confusion as to where the operator should load paper into the tray whenever the tray is accessed, no matter where the tray stack edge guides are positioned for different paper sizes. An accordion-folded, reeled, or other expandable and contractible member operatively connects between the repositionable stack edge guide and the opposite end of the tray, extending above the tray stacking surface therebetween.

Abstract: A method for tracking facsimile jobs may be employed to examine, at an originating device, an incoming facsimile transmission for information indicating that the transmission originated at the originating device, in which case the incoming message is determined to be a return message which is the result of an error condition. In a preferred embodiment, a return message so determined is not printed, whereas other types of incoming messages are determined to be valid for printing and are processed accordingly. Further, certain incoming messages that are detected as representing “round-trip jobs” are distinguished from return messages and the former are considered valid for printing.

Abstract: A constant torque split is maintained between a pair of drive motors for the photoreceptor belt of an electrophotographic printing machine. By varying the voltage applied to the motors according to the speed of the photoreceptor belt, the torque applied by each motor can be continuously balanced at a predetermined relationship to apply a constant torque and the desired speed may be accurately maintained. To better refine the implementation, the relationship include a ratio and an offset which may be applied, to one of the motors. Furthermore, this offset is ramped up during motor acceleration to optimize motion quality and system performance.

Abstract: A method of improving edge rendering of objects includes dilation (or contraction) of an object's tag plane by one or more pixels into the surrounding region, with the adjacent tag region having a corresponding contraction (or dilation). The objects of interest (e.g., white text) are first identified; the corresponding object tag plane is then spread or choked, in a fashion analogous to trapping. In the case of negative text on a tint background, by expanding the tag plane for the negative text object, the text hint would be forced one pixel into the tint object plane everywhere along the perimeter of the negative text. This could then enable greatly improved negative text rendering.
