摘要： A computer printer having a frame contained within a housing, a media transport and printing mechanism attached to the frame within the housing is provided with at least one debris shield positioned above the printing mechanism to protect it from falling debris. The at least one debris shield may be positioned below an air flow path generated by printer ventilation, and the printer may employ a transfer surface on which an image is generated prior to transfer to a media sheet, and above which the debris shield is positioned. Stripper fingers strip the media sheet from the transfer surface and webs between the stripper fingers form an air flow barrier to prevent debris transmission through gaps between the fingers.

摘要： A method and an apparatus (10) for cleaning an ink jet print head (12) draws contaminates from orifices (20) in the print head onto an orifice plate (14) and then wipes the orifice plate. The maintenance apparatus includes a purge cap (24) that has a recessed region (40) with an open end (36). The top side margins (42) of the open end define a periphery (44) around which a seal (60) is positioned. A positioning system (30) urges the orifice plate against the seal. A heating system (128) and a vacuum system (74) cooperate to create a differential pressure across the orifices to draw contaminates carried by liquid ink out of them and onto the orifice plate. A resilient wiper assembly (26) including a spring-mounted wiper blade (78) is positioned in and nominally extends outwardly of the recessed region of the purge cap. The positioning system moves the purge cap downwardly against the orifice plate so that the wiper blade engages and wipes the contamination from the orifice plate.

摘要： The method of the invention converts colors resident in a first device color space to gray levels for reproduction in a color or monochrome rendering device. The method initially converts the color values resident in the first device color space to corresponding color values in a device independent color space. Next, the resulting color values in the device independent color space are converted to further color values in the same color space that correspond to color values resident in the color space of a target color rendering device. The further color values from the device independent color space are then converted to corresponding gray levels so that they may be rendered by either the target color rendering device or a different color or monochrome rendering device. The use of an intermediate gamut conversion within the device independent color space enables more precise gray representations to be achieved for certain color representations.
摘要翻译：本发明的方法将驻留在第一设备颜色空间中的颜色转换成用于在彩色或单色渲染设备中再现的灰度级。该方法首先将驻留在第一设备颜色空间中的颜色值转换为与设备无关的颜色空间中的相应颜色值。接下来，将设备独立颜色空间中产生的颜色值转换为与驻留在目标显色设备的颜色空间中的颜色值相对应的相同颜色空间中的另外的颜色值。然后将来自设备独立颜色空间的另外的颜色值转换为相应的灰度级，使得它们可以由目标显色设备或不同的颜色或单色渲染设备渲染。在设备独立颜色空间内使用中间色域转换可以实现某些颜色表示的更精确的灰色表示。

摘要： A printing system for printing documents that includes a recurring image. The printing system includes a computer connected to a printer over a communication link. The computer generates a named sequence to represent the recurring image and a parameter. The parameter value provides the printer with information that can be used to optimize the processing and printing of the named sequence.

摘要： A PostScript-compatible printer accepts PostScript language commands that indicate both device-dependent and device-independent color specifications. Such a printer in accordance with the invention has a PostScript interpreter that implements Level 1 and Level 2 color rendering pipelines. In the Level 1 color rendering pipeline, the interpreter converts device-dependent color specifications to internal color specifications using a calibrated n-dimensional operation. In the Level 2 color rendering pipeline, the interpreter converts device-independent color specifications to device-dependent color specifications using a standard PostScript color rendering dictionary, and then passes such device-dependent color specifications into the Level 1 pipeline for further processing.
