    • A heat and pressure fusing assembly including an ink contamination-free release agent management (RAM) system is provided for supplying and applying release agent material onto an outer surface of a heated fuser roller suitable for fusing toner filled-in areas of a preprinted form. The ink contamination-free RAM system includes a housing defining a sump containing release agent material, a donor roller mounted partially within the sump for contacting, and applying release agent material onto, a surface of a heated fuser roller, and a metering roller mounted within the sump for moving and transferring a layer of release agent material from the sump onto the donor roller. The metering roller has a low energy surface layer made of PerFluoroAlkoxy (PFA) for preventing ink contaminants reaching the donor roller from transferring onto the metering roller, thereby preventing poor application of release agent onto the metering roller, and image defects resulting from such poor application.
    • 提供了一种包括不含油墨污染的脱模剂管理(RAM)系统的热和压力熔融组件,用于将释放剂材料供应并施加到适于熔化预先打印形式的调色剂填充区域的加热定影辊的外表面上。 无油墨的RAM系统包括限定含有脱模剂材料的贮槽的壳体,部分地安装在贮槽内的供体辊,用于接触并将脱模剂材料施加到加热的定影辊的表面上,以及安装在其中的计量辊 用于将一层脱模剂材料从贮槽移动并转移到供体辊上的贮槽。 计量辊具有由全氟烷氧基(PFA)制成的低能量表面层,用于防止油墨污染物到达供体辊转移到计量辊上,从而防止脱模剂施加到计量辊上的不良应用以及由于这种差的应用导致的图像缺陷 。
