摘要： Apparatus and method for minimizing ghost defect are disclosed. Ghosting results in interdocument bands when paper size is changed and process control instability due to using the interdocument zone (IDZ) for voltage and density control. A controller retrieves feedback measurements of the IDZ and sheet zone (SZ) non-uniformity. In response to the measurements, the transfer current IDZ level is controlled to minimize differences in subsequent charging, photodischarge and development.

摘要： A method and apparatus can, while operating a printing device in a test mode, supply a changed transfer field to a marking material transfer device. The changed transfer field is less than or more than the standard transfer field. The method and apparatus disable operations of other marking material transfer devices of the printing device to isolate the marking material transfer device. Further, the method and apparatus compare the actual amount and/or spatial distribution of marking material transferred to a recipient surface (to which the first marking material transfer device transfers the marking material) against a predetermined standard. Then, if the actual amount of marking material transferred to the recipient surface is different than the predetermined standard, the method and apparatus can identify the first marking material transfer device as being a potential source of printing defects.
摘要翻译：一种方法和装置可以在测试模式下操作打印装置的同时，将改变的传送场提供给标记材料传送装置。改变的传输字段小于或大于标准传输字段。所述方法和装置禁止打印装置的其他标记材料传送装置的操作以隔离标记材料传送装置。此外，该方法和装置将转移到受体表面的标记材料（第一标记材料转移装置转移到标记材料）的实际量和/或空间分布与预定标准进行比较。然后，如果转移到接受面的标记材料的实际量不同于预定标准，则该方法和装置可以将第一标记材料转移装置识别为潜在的印刷缺陷源。

摘要： A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.
