    摘要: A cleaning blade assembly within a printing device is positioned to contact a surface to be cleaned. There is a first opening within the cleaning blade assembly and a first pin within the first opening. There is also a second opening within the cleaning blade assembly, and a second pin within the second opening. The first and second pins connect the cleaning blade assembly to the printing device. The first pin has a first cam surface that is rounded and is off-center with respect to the axis of the first pin. The cam surface is parallel to the axis of the first pin and is positioned within the first opening such that rotation of the first pin within the first opening causes the cleaning blade assembly to move in a direction perpendicular to the axis of the first pin.

    摘要: Systems and methods of marking control achieve improved image quality in a multipass marking process by taking into account positioning errors that have already occurred in prior marking passes while building the image, and compensates for them in real-time by modifying the remaining interlace locations of the marking subsystem in order to minimize predicted image quality defect perception in the resultant image. The adjustment are preferably based on minimizing a defect perceivability metric. One such suitable metric is a frequency metric, preferably the power spectral density of the resultant image evaluated at the fundamental frequency (1/D), where D represents the spacing of marking devices, such as the spacing of print head nozzles.

    摘要: Methods and systems for automatically detecting multi-object anomalies at a traffic intersection utilizing a joint sparse reconstruction model. A first input video sequence at a first traffic location can be received and at least one normal event involving P moving objects (where P is greater than or equal to 1) can be identified in an offline training phase. The normal event in the first input video sequence can be assigned to at least one normal event class and a training dictionary suitable for joint sparse reconstruction can be built in the offline training phase. A second input video sequence captured at a second traffic location similar to the first traffic location can be received and at least one event involving P moving objects can be identified in an online detection phase.

    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: An improved development system for an electrophotographic system comprises a reload defect detector for generating a signal corresponding to a potential for reload defect detected in an image to be developed by an electrophotographic system; and a magnetic roll speed selector for selecting a rotational speed for a magnetic roll in a development system of the electrophotographic system, the selected rotational speed corresponding to the generated reload defect potential signal. The speed of the magnetic roll is selected to be a lower speed in response to the potential for reload defect being relatively low. The slower rotation of the magnetic roll prolongs the life of the developer and extends the operational life of the development system before corrective action is needed.
