摘要： An apparatus and method for homogenizing developer allow variations in image quality between marking engines to be reduced. The apparatus includes a developer homogenizer in communication with the marking engines which receives developer from the first marking engine and developer from the second marking engine and combines them. A first portion of the combined developer is returned to the first marking engine for forming images therewith and a second portion of the combined developer is returned to the second marking engine for forming images therewith.

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： An apparatus develops an electrostatic latent image on a charge-retentive surface. A donor roll is selectably rotatable in a process direction and in a reverse direction relative to the process direction. A toner mover loads toner particles onto a portion of the surface of the donor roll. A metering blade is disposed downstream of the toner mover in the process direction. A seal is disposed upstream of the toner mover in the process direction, and is adapted to remove at least approximately half of the undeveloped toner from the donor roll.
