    摘要： The present application is directed to second transfer areas and methods of transfer toner images from an intermediate member to a media sheet. The second transfer area comprises a second transfer nip formed between a second transfer roller and a back-up roller. The media path moves through this nip with the toner images on the intermediate member being transferred to the media sheets. The amount of force applied by the second transfer roller affects the transferability of the toner images to the media sheet. Further, the intermediate member may contact the second transfer roller at soft nip and hard nip locations. The lengths of these nips may also affect the transferability of the toner images.

    摘要翻译： 本申请涉及将调色剂图像从中间构件转印到介质片材的第二转印区域和方法。 第二转印区域包括形成在第二转印辊和支撑辊之间的第二转印夹持物。 介质路径移动通过该辊隙，中间构件上的调色剂图像被转印到介质片材上。 由第二转印辊施加的力的影响影响调色剂图像到介质片的转印性。 此外，中间构件可以在软压区和硬压区位置处接触第二转印辊。 这些胶片的长度也可能影响调色剂图像的转印性。

    摘要： The present application is dieted to methods and devices for determining the absence of media sheets within an image forming device. In one embodiment, a support section configured to hold a stack of media sheets is positioned in an input area of the image forming device. A pick mechanism is positioned to contact a top-most sheet in the support section. The pick mechanism may include a pick motor and a pick roller. A sensor roller may fee positioned to contact the top-most media sheet at a position spaced away from the pick roller. A controller may determine the absence of a media sheet based on the movement of the sensor roller after a predetermined movement of the pick motor.
