摘要： A system for detecting stripper device blockage in a printing system is disclosed. The system includes a fusing member which during operation contacts a sheet of printer media to fuse a marking material to the sheet, a stripping device configured to apply pressurized air from an air supply through at least one orifice to the fuser member in order to separate the sheet from the surface and a flow measurement device in line with the air supply which measures air flow. The air flow device will assist in performing an assessment check which may include taking a baseline measurement of air flow and a diagnostic measurement of air flow. In the case where the difference between the diagnostic measurement and baseline measurement is above a different threshold, corrective action may be taken.

摘要： An improved fuser includes a fuser member, a pressure member that forms a nip with the fuser member through which copy sheets pass to have images fused thereon and an air knife to assist in peeling copy sheets from the fuser member. The air knife has a device connected to it that blocks entrained airflow between the fuser and air knife to reduce fuser cooling and power loss.

摘要： An enhanced sheet stripping method and apparatus for stripping toner image carrying copy sheets from a surface of a moving heated fusing member forming a fusing nip. The apparatus includes (a) a moving assembly for moving a cut sheet towards the fusing nip; (b) a sheet curling device positioned upstream of the fusing nip relative to movement of the cut sheet for inducing a desired pre-curl in the cut sheet before the cut sheet enters the fusing nip; and (c) a sheet stripping device positioned downstream of the fusing nip for stripping the cut sheet from contact with the surface of the moving heated fusing member as the cut sheet exits the fusing nip. The method includes inducing a desired curl in the cut sheet before the cut sheet enters the fusing nip and enhanced stripping the cut sheet from contact with the surface of the fuser roll as the cut sheet exits the fusing nip.
摘要翻译：一种增强的片材剥离方法和装置，用于从形成定影辊隙的移动的加热定影构件的表面剥离带有复印纸的调色剂图像。该装置包括：（a）移动组件，用于将剪切片材朝向定影辊隙移动; （b）相对于切割片材的运动而定位在定影辊隙的上游的片材卷曲装置，用于在切割片材进入定影辊隙之前在切割片材中引起所需的预卷曲; 和（c）位于定影辊隙下游的片材剥离装置，用于在切割片材离开定影辊隙时剥离切割的片材与移动的加热熔融部件的表面接触。该方法包括在切割的片材进入定影辊隙之前在切割的片材中引起期望的卷曲，并且当切割片材离开定影辊隙时，增强剥离切割片材与定影辊表面的接触。

摘要： A printing system includes first and second marking engines. First and second fusers are associated with the marking engines, respectively. The printing system has a first mode of operation in which print media is fused by both fusers and a second mode of operation in which at least a portion of the print media is fused by the second fuser, which portion has not been previously fused by the first fuser. The second fuser has first and second fuser operating modes when the printing system is in the first and second modes of operation, respectively. The second fuser applies a first energy input to the print media in the first fuser operating mode and a second energy input, different from the first energy input, to the print media in the second fuser operating mode.

摘要： A fluid cartridge for dispensing fluid, such as liquid ink for a drop on demand ink jet printer, includes a housing that encloses a capillary chamber, and has an outlet port through the one wall of the housing into the capillary chamber. Capillary material in the capillary chamber is arranged so that it has a higher density adjacent the outlet port than away from the outlet port, to enhance the flow of the fluid toward the outlet port. The interior of the capillary chamber is structured to provide greater compression to the capillary material around the outlet port, and provide stability to retain the variable compression of the capillary material.
