摘要： An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet. The sheet passes through a nip formed between the charge receptor and a moving transfer belt. Upstream of the nip, the belt forms a shallow angle relative to the charge receptor; downstream of the nip, the belt forms a steep angle relative to the charge receptor. This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.

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 electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet by providing an electric field of predetermined magnitude at a transfer zone. The transfer station includes a rotatable transfer member, with a cleaning corotron associated therewith. A control system for maintaining a constant current at the transfer zone takes into account a current supplied by the cleaning corotron. The control system can also take into account current leakages associated with the transfer member.

摘要： Electrodes are embedded in a biased charge roller of a xerographic device. The electrodes, which may run the length of the roller, are deposited on an insulating substrate. A semi-conductive conformable layer of a flexible elastomer covers the electrodes. The semi-conductive conformable layer limits current flow between electrodes and relaxes charge deposited on the roller surface. Stationary pre-nip and post-nip contacts apply the bias to the imbedded electrodes. The electrodes in the post nip region are biased to VPOST. The electrodes positioned in the pre-nip regions are either grounded or biased to VPRE

摘要： Provided herein is a system for using a cleaning web in an electrostatic printing process to provide a uniform and thin wax layer on the fuser roll and thereby minimize print history effects, reduce triboelectric voltages on the fuser roll and provide uniform and improved release of the toner from the fuser roll. The application of this beneficial thin film to the fuser roll is accomplished by impregnating the cleaning web with a wax material that is substantially the same as the wax material in the toner used in the system. This impregnated wax, therefore, has the same release and triboelectric properties as the wax in the toner and therefore will not attract residual toner but will rather repel it.

摘要： A printing system includes first and second marking devices for applying images to print media. A first primary fusing device is associated with the first marking device for applying a primary fusing treatment to the images applied to print media by the first marking device. A second primary fusing device is associated with the second marking device for applying a primary fusing treatment to the images applied to print media by the second marking device. At least one secondary fusing device receives printed media from the first and second marking devices. The secondary fusing device selectively applies a further fusing treatment to at least a portion of the images applied to the printed media to increase a uniformity of an appearance characteristic between printed images generated by the first marking device and the second marking device.

摘要： The magnitude and polarity of the voltage on the fuser roll surface is controlled by either electronic charge application means or by applying charge control agents to the fuser. For negative toner, the fuser roll voltage must also be negative (and visa versa). This will repel the negative toner at the entrance to the fuser nip, prevent the toner from transferring to the fuser roll at the entrance of the fuser nip and preclude the formation of NVO and consequently prevent MOC.

摘要翻译： 定影辊表面上的电压的大小和极性由电子充电应用装置或通过向定影器施加充电控制剂来控制。对于负色调剂，定影辊电压也必须为负值（反之亦然）。这将排斥定影辊隙入口处的负色调剂，防止调色剂转移到定影辊入口处的定影辊，并排除NVO的形成，从而防止MOC。
