摘要:
Method, system and computer-readable medium to provide hybrid control of sheet transport modules in a processing device. The method of controlling a processing device includes setting velocity of a first sheet transport module of the processing device to a predetermined velocity value. The method further includes controlling torque of the first sheet transport module when a sheet transfers from the first sheet transport module to a second sheet transport module of the processing device.

According to aspects described herein, there is disclosed an apparatus and method for dynamically registering an image relative to a target substrate media in a printing system. The apparatus and method including a marking engine, transport, sensing system and a correction module. The marking engine for generating the image for transfer to the target substrate media. The transport for moving the target substrate media along the path in the process direction to receive the image in a transfer area from the marking engine. The sensing system for detecting a characteristic of at least one other substrate media moved previously by the transport. Also, the correction module for altering the image generated by the marking engine based on at least one signal from the sensing system. The characteristic of the at least one other substrate media being detected from at least two portions of the path, the two portions disposed on opposed sides of the transfer area in the process direction.

One disclosed feature of the embodiments is a method of aligning transport modules in a printing system, the method comprising a step (a) including passing at least one substrate media in a process direction through two adjacent belt driven transport modules with at least one module belt steering control disabled. The method also comprising a step (b) including detecting a position of at least one module transport belt in a cross-process direction using an edge sensor. Further, the method comprising a (c) including aligning the two adjacent transport modules based on the detected cross-process position.
摘要:
A defect analysis system for a xerographic print engine includes a residual mass sensor that senses the two-dimensional signature structure of residual mass remaining on a photoconductive or other substrate surface after image transfer. Preferably, the sensor is a full width array that spans substantially an entire width of the photoconductive surface. This information is then processed and analyzed to determine a specific type of transfer defect present. This may include the quantified level of defect for each detected type. The defect analysis system may also include a closed-loop control system that can adjust various xerographic process parameters using feedback based on the identification and optionally magnitude of each specific defect type. The identified print quality defect, such as mottle, streaks, point deletions, graininess, etc. can then be used to determine a customized corrective control action to be taken by the feedback control of the xerographic print engine to remedy or compensate for the defect(s).
摘要:
A system for printing media includes a plurality of marking engines for outputting printed media in a stream, a media path system operable to transport the printed media from the marking engines to one or more finishing stations such that the streams are merged and transported one on top of the other and one or more finishing stations capable of compiling media in groups of 2 or more sheets for post processing the printed media into one or more completed jobs.
