  • Patent number: 8265514
    Abstract: Toner is removed from a skive mount in a dry electrophotographic printer. An end block is disposed at one end of the rotatable development member, and a skive mount disposed adjacent to the development member connects a skive to the end block. A timing device measures time intervals of printer operation. A process-control time interval and a cleaning time interval that is a non-negative multiple of the process-control time interval are selected. Prints are made until the process-control time interval elapses. A process-control patch is produced in a process-control frame. Once the cleaning interval has elapsed, in the process-control frame, a backup bar is lifted lift away from the photoreceptor, then, after a selected time delay, brought into physical contact with at least one point on the end block, so that toner is removed from the skive mount.

  • Patent number: 8227165
    Abstract: A receiver having an image side and a non-image side bent in a bend area including a bend axis. Toner is deposited on the image side of the receiver in the bend area using an electrophotographic print engine. The deposited toner is fused to the receiver. During or after fusing, the fused toner is heated to a selected fusing temperature greater than or equal to the Tg of the toner. A heat-shrinkable film is affixed to the heated toner after heating the toner, wherein the Tg of the film is greater than the Tg of the toner. The toner is cooled below its Tg after affixing the film. The bend area of the receiver is reheated after cooling the toner, so that the temperature of the heat-shrinkable film rises above its Tg, the heat-shrinkable film contracts, and the receiver bends at the bend axis.

  • Patent number: 8224226
    Abstract: A method of increasing productivity in a reproduction apparatus wherein a first print engine and a second print engine are coupled by an inverter and synchronized. Each sheet of a plurality of receiver sheets is selectively printed in an invert mode or a non-invert mode. A difference of a travel time of a first receiver sheet in an invert path through the inverter in the invert mode as compared to a travel time of a second receiver sheet in a non-invert path through the inverter in the non-invert mode is adjusted so that the difference is an integral multiple of a period between the receiver sheets. Frames on a dielectric support member in the appropriate print engine are skipped when switching between invert mode and non-invert mode.
