摘要： In a development unit for electrostatographic printing, where toner particles are conveyed by a rotating roll to a charge-retentive surface, a groove is defined in the interior surface of the housing which retains the toner particles, the groove extending along a portion of the circumference of the roll. The groove facilitates redistribution of toner particles which accumulate at the bottom of the housing near an end of the roll.

摘要： A method and apparatus for delivering a uniform supply of toner to a development zone in an electrostatographic system is disclosed. Additional toner control in the form of magnets located near the donor member attract toner to the toner pick-up area and insure that a constant supply of toner reaches the development zone. The additional control of toner is especially useful when the supply of toner to the toner pick-up area is limited or the toner does not naturally flow to the toner pick-up area.. The toner supply is enhanced by a stationary magnet located adjacent the donor member and a magnet located on the charge metering blade. Both of the additional toner supply magnets form magnetic brushes of toner particles on the donor member surface, these magnetic brushes insuring a constant supply of toner to the development zone despite problematic development conditions.
摘要翻译：公开了一种用于将均匀供应的调色剂输送到静电照相系统中的显影区域的方法和装置。以位于供体构件附近的磁体形式的附加调色剂控制将调色剂吸引到调色剂拾取区域，并确保恒定供应的调色剂到达显影区。当向调色剂拾取区域供应调色剂受限或调色剂不会自然流到调色剂拾取区域时，调色剂的附加控制是特别有用的。通过位于相邻的调色剂位置的固定磁体增强了调色剂供应施主构件和位于电荷计量刀片上的磁体。两个附加的调色剂供应磁体在供体构件表面上形成调色剂颗粒的磁刷，尽管有问题的显影条件，这些磁刷确保向开发区恒定供应调色剂。

摘要： Roll fuser apparatus for fixing toner images on copy substrates. This apparatus is characterized by simplicity of design and serviceability. To this end, the fuser roll, pressure roll and a weighted wick are all supported for vertical movement such that raising the pressure roll which is below the fuser roll which, in turn, is below the wick causes engagement with the fuser roll and then engagement between the fuser roll and wick. Downward movement of the pressure roll will effect disengagement of the pressure roll from the fuser roll as well as automatic disengagement of the wick from the fuser roll.
摘要翻译：卷筒定影装置，用于将复印基板上的调色剂图像定影。该设备的特征在于设计简单和可维护性。为此，定影辊，压力辊和加重的芯都被支撑用于垂直运动，使得升高低于定影辊的定影辊下方的压力辊导致与定影辊的接合，然后接合在定影辊和灯芯之间。压辊的向下运动将导致压辊与定影辊脱离，以及芯与定影辊的自动脱离。

摘要： A multi-stage fusing system for fixing toner images to copy substrates of various weights has a primary fuser and a secondary fuser in series with the primary fuser. Various weights of print substrates may have toner images fixed thereon by the primary fuser. The various print substrates are then transmitted to the secondary fuser or directly to a finishing area. The secondary fuser is designed specifically for heavier weight substrates and a bypass paper path is provided for allowing lighter weight substrates to bypass the secondary fuser.

摘要： In a xerographic development unit, particularly a unit for applying single-component magnetic toner such as used in MICR printing, the end of a donor roll which applies toner to the surface of a charge receptor is provided with a magnetic seal. The magnetic seal extends around at least a portion of the circumference of the roll, and defines a set of alternating magnetic poles arranged in bands which alternate along the length of the roll. The magnetic seal forms a uniform gap relative to the surface of the roll, the gap being sufficiently large to allow a turnover of toner particles therethrough. The design minimizes mechanical stresses on the toner, which in turn avoids the generation of frictional heat in the toner. A member defining magnetic poles can also be used as a shim for mounting a charge/metering blade within the development unit.
摘要翻译：在静电复印显影单元中，特别是用于施加诸如用于MICR印刷的单组分磁性调色剂的单元，向电荷接收器的表面施加调色剂的供体辊的端部设置有磁性密封。磁性密封件围绕辊的圆周的至少一部分延伸，并且限定了沿着辊的长度交替的带状布置的一组交变磁极。磁性密封件相对于辊的表面形成均匀的间隙，间隙足够大以允许调色剂颗粒通过其周转。该设计使调色剂上的机械应力最小化，这反过来又避免了在调色剂中产生摩擦热。定义磁极的构件也可以用作将充电/计量刀片安装在显影单元内的垫片。

摘要： In a xerographic printer having single-component development, a metering blade that creates a uniform layer of toner on the developer roll is bowed with the ends of the blade curved toward the developer roll. The bowed blade results in more uniform metering pressure across the developer roll.
