Abstract: Utilization of fringe field tailoring pixels with sub-pixel patterns are introduced into the bitmap of an image to obtain local control of the normal and tangential electric fields and thereby improve image development. These fringe field tailoring pixels embody multiple sub-pixel pulses so as to alter the electric fields as developed upon the photoreceptor. These fringe field tailoring pixels compensate for the otherwise undesirable electric fringe fields as found on the edge of image shapes. These undesirable fringe fields pull toner away from image edges and cause other “slow toner” effects, particularly in high speed systems. Application of fringe field tailoring pixels with their sub-pixel patterns to the edge of an image shape modifies the fringe electric fields so as to encourage pulling toner onto the photoreceptor at the image edge. This ensures adequate toner supply to all parts of the image so that the desired printing pixels will print as intended.

Abstract translation: 将具有子像素图案的边缘场裁剪像素的利用引入到图像的位图中，以获得正常和切向电场的局部控制，从而改善图像开发。 这些边缘场裁剪像素体现了多个子像素脉冲，以便改变在感光体上显影的电场。 这些边缘场剪裁像素补偿了在图像边缘上发现的不期望的电边缘场。 这些不需要的边缘区域将图像边缘的调色剂从图像边缘拉出并导致其他“慢调色剂”效应，特别是在高速系统中。 将其子像素图案的边缘场裁剪像素应用于图像边缘的边缘修改边缘电场，以便鼓励在图像边缘上将调色剂拉到感光体上。 这确保了足够的碳粉供应到图像的所有部分，使得期望的打印像素将按预期打印。

Abstract: The pages of a book being held at least partially open may be sequentially automatically turned over from one side of the book to the other by pivoting an elongated arm from one side of the book toward the other and turning over individual pages with a vacuum head pivoting relative to the elongated pivoted arm about a different pivot axis as the elongated arm moves to reduce undesirable forces on the individual book pages being turned over. The vacuum head may initially pivot to bend the edge of an individual page up away from the book, to aid in page separation, and then subsequently differently pivot to help peel the same page gently away from the vacuum head and flip it over onto the opposite side of the book. This may be assisted by moving frictional belts on the vacuum head.

Abstract: An apparatus for developing in a development zone a latent image recorded on a surface, including; a housing defining a chamber storing at least a supply of toner therein. A donor roll disposed of at least partially in the chamber of said housing and spaced from the surface. The donor roll is adapted to rotate about a longitudinal axis to transport toner to the development zone in a region opposed from the surface. An elongated electrode member is mounted stationarily in the development zone and extending in a direction transverse to the longitudinal axis. The electrode member includes a flexible thin sheet having a plurality of elongated wires with adjacent wires which are spaced from and substantially parallel to one another. The electrode member is positioned in the development zone and spaced between the surface and said donor roll. The electrode is electrically biased to detach toner from said donor roll, so as to form a toner powder cloud in the development zone with detached toner from the toner cloud developing the latent image.
