摘要： A printer having a system to manage the output path of wet printed media is disclosed. In such a system, the wet printed media are held for a time before being ejected into an output tray to avoid the smearing of the wet print markings made on the media. The system achieves this holding time by causing the wet printed media to travel an additional distance over movable ramps before being ejected. In addition, the movements of the ramps are synchronized with the various operations in the printing cycle of the printer.
摘要翻译：公开了一种具有管理湿印刷介质的输出路径的系统的打印机。在这样的系统中，湿印刷介质在被排出到出纸托盘之前被保持一段时间，以避免在介质上产生的湿印标记的拖尾。该系统通过使湿式打印介质在弹出之前在可移动坡道上行进另外的距离来实现该保持时间。此外，斜面的移动与打印机的打印周期中的各种操作同步。

摘要： A media separation system is provided for separating individual sheets from a stack of media. The media separation system has a pressure plate positioned at an angle to support the stack of sheets along an incline. The pressure plate has an upper and lower end, with a relieved area formed in the lower end of the pressure plate. The media separation system also has a pick roller disposed in juxtaposition to the relieved area of the pressure plate to engage and separate a top sheet from the stack of sheets. The pick roller has a width that is more narrow than that of the relieved area in the pressure plate. A spring-like mechanism is provided to urge the pressure plate toward the pick roller to cause the pick roller and the pressure plate to work cooperatively to depress the sheets of media beneath the pick roller into the relieved area of the pressure plate. This causes formation of a primary depression in the stack of sheets. The media separation system further includes a ribbed surface positioned elevationally below the pressure plate and pick roller to support and register leading edges of the stack of sheets. The ribbed surface has a raised rib positioned centrally beneath the pick roller to create a secondary depression in the stack of sheets that bows in an opposite direction from the primary depression. The dual depressions create a distinct shape that enables the top sheet to separate easily from the stack when the pick roller is rotated.
摘要翻译：提供了一种介质分离系统，用于将各个片材与一叠介质分离。介质分离系统具有以一定角度定位的压板，以沿着倾斜度支撑堆叠的片材。压板具有上端和下端，缓冲区形成在压板的下端。介质分离系统还具有拾取辊，该拾取辊与压板的释放区域并置设置，以将顶片与堆叠的片材接合并分离。拣选辊的宽度比压板缓冲区域的宽度更窄。提供弹簧状机构以将压板推向拾取辊，以使拾取辊和压板协同工作以将拾取辊下方的介质片压入压板的释放区域。这导致在堆叠的片材中形成初级凹陷。介质分离系统还包括位于压板正下方的肋状表面和拾取辊，以支撑和对准纸叠的前缘。肋状表面具有定位在拾取辊下方中心的凸起肋，以在与主凹陷相反的方向上弯曲的片材堆叠中产生次级凹陷。双凹陷形成了独特的形状，使得当拾纸辊旋转时，顶片可以容易地与纸叠分离。

摘要： An output roller for propelling a media sheet, for example in a printer, is disclosed. A plurality of protrusions is selectively positioned on the output roller. As the media sheet exists a media path, the rear edge of the media sheet is caught by the protrusions and the rear edge is further pushed forward into an output stack. Preferably, the protrusions are flexible.

摘要： A sensing system is used to sense when a stack of sheet material reaches a critical height. A light beam is shone onto a region on the surface of the stack to form a lighted area. Changes in the height of the stack of sheet material results in changes in size of the lighted area of the beam shining on the surface of the stack. A light detector monitors a zone on the stack surface in which the amount of light being monitored as shining on the zone varies in accordance with changes in size of the lighted area. The detection system detects when the lighted area has reached a predetermined size by detecting when the light shining on the zone has reached a predetermined point. The system then provides an indication that the stack surface has reached a critical height, in other words that the stack surface has reached a critical distance from the light source.
摘要翻译：感测系统用于感测堆叠的片材何时达到临界高度。光束照射在堆叠表面上的区域上以形成点亮区域。片材堆叠的高度的变化导致在堆叠表面上照射的光束的照明区域的尺寸的变化。光检测器监测堆叠表面上的区域，其中根据照明区域的尺寸的变化，被监视的光量在该区域上发光。检测系统通过检测在区域上照射的光到达预定点的时间来检测点亮区域何时达到预定的尺寸。然后，系统提供堆叠表面已经达到临界高度的指示，换句话说，堆叠表面已经达到与光源的临界距离。
