摘要： A high differential air pressure assisted blotting device for conditioning, on an image bearing member, liquid developer images consisting of charged toner particles and carrier liquid. The high differential air pressure blotting device includes a movable porous blotter belt forming an endless loop and having an outer surface for contacting and blotting carrier liquid from an image being conditioned, and a backup roller positioned at a first location within the endless loop for contacting a first portion of the blotter belt to gently urge the blotter belt into blotting-contact with the image being conditioned. Importantly, the high differential air pressure blotting device includes a high differential air pressure assembly positioned at a second location spaced from the image being conditioned so as not to disturb the image, and from the first location for contacting a second portion of the blotter belt and applying a high differential air pressure to such second portion to force carrier liquid out of the blotter belt before such second portion recontacts an image being conditioned.

摘要： A method and apparatus for filtering and sensing a developer fluid in a printing or copying machine for processing purposes. In order to insure that developer fluid reclaimed from a developing process is free from contamination, a filter/sensor system is provided in the reclaimed fluid path. The reclaimed fluid passes through the filter and then the sensor senses the amount of toner remaining in the fluid. If the toner contamination level is too high, the fluid is recirculated to the filter where it is re-filtered. This process is repeated until the reclaimed fluid is free of contaminants. The filter/sensor system can also indicate process failure in the developing system. Cleaning a developer housing is yet another use for the recirculating sensor/filter process. In this mode the developer fluid in the toner sump is circulated through the sensor/filter until all of toner has been removed from the fluid. The cleaned fluid is reused in the system and another color of toner can now be added to the developer housing.

摘要翻译： 一种用于过滤和感测印刷或复印机中的显影剂流体用于处理目的的方法和装置。 为了确保从显影过程回收的显影剂流体不受污染，在再生流体路径中提供过滤器/传感器系统。 回收的流体通过过滤器，然后传感器感测残留在流体中的调色剂的量。 如果调色剂污染水平太高，则将流体再循环到过滤器，在那里重新过滤。 重复该过程直到回收的流体没有污染物。 过滤器/传感器系统也可以指示显影系统中的过程故障。 清洁显影器外壳是再循环传感器/过滤器过程的另一个用途。 在这种模式下，调色剂槽中的显影剂流体通过传感器/过滤器循环，直到所有调色剂从流体中移除。 清洁的流体在系统中重复使用，并且现在可以将另一种颜色的调色剂添加到显影剂外壳中。
