    • A cleaning and spots blade lubricating apparatus and method, the apparatus for the method includes (a) a pre-clean charging device including a first bias having a first polarity; (b) a cleaning device having (1) a cleaning mode including a second bias having a second polarity opposite the first polarity, and (ii) a non cleaning mode including a third bias having a third polarity; (c) a spots blade for removing random spots from a moving photoreceptor surface being cleaned; and (d) a programmable controller connected to the pre-clean charging device and to the cleaning device for forming a lubricating residual toner stripe on a portion of the moving photoreceptor surface, the programmable controller intermittently and momentarily switching the cleaning device from the cleaning mode to the non-cleaning mode for forming the lubricating residual toner stripe.
    • 一种清洁和刮刀润滑装置和方法,所述方法的装置包括(a)预清洁充电装置,其包括具有第一极性的第一偏置; (b)清洁装置,具有(1)包括具有与第一极性相反的第二极性的第二偏压的清洁模式,以及(ii)包括具有第三极性的第三偏压的非清洁模式; (c)用于从被清洁的移动感光体表面去除随机点的斑点刀片; 和(d)连接到预清洁充电装置和清洁装置的可编程控制器,用于在可移动感光体表面的一部分上形成润滑残留调色剂条,所述可编程控制器间歇地且瞬时地将清洁装置从清洁模式切换 到用于形成润滑残留调色剂条的非清洁模式。

    • 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.
    • 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。
