An apparatus includes a xerographic cleaning blade, an actuator member operatively connected to the cleaning blade and movable over a first stroke from a first actuator position to a second actuator position, and a damper operatively connected to the actuator member. As the actuator member moves over the first stroke the cleaning blade moves from a first blade position to a second blade position. The damper allows substantially uninhibited actuation of the actuator member over a first portion of the first stroke. The damper damps actuation of the actuator member over a second portion of the first stroke.

Cleaning blade control apparatus and method

A fluid flow system for continuously monitoring the flow of fluid including fluid flow conduit with an upstream side and a downstream side, sensors and fluid flow elements, with the method for analyzing the operation of a fluid flow system by determining whether the fluid flow subsystem of the main system is operating properly, inputting a sensor reading of the parameter in the fluid flow of the main system and outputting an error indication of the main system.

A xerographic CRU (Customer Relpaceable Unit) for an electrophotographic printing machine. The xerographic CRU has retaining features and cooperates with a drive module with certain retractable features that allow the insertion and removal of the CRU without causing damage to the photoreceptor and other critical subsystems. The unit further has many locating members for other subsystems so that critical tolerances are maintained. An interface with a single handle assembly retracts/unlocks and extends/locks the drive module and the associated CRU subsystems into an operative position. The CRU also has electrical and drive connections for the cleaning system, the charging system and transfer/detack.

A channel for recirculating a stream of air located adjacent a stream of marking particles exiting substantially tangentially from a marking particle transport member within a developer unit is provided. The stream of marking particles defines an inner boundary thereof extending tangentially from a first position adjacent to the transport member and defines an outer boundary thereof spaced from the transport member and the inner boundary. The channel includes a first member positioned outside the stream of marking particles. At least a portion of the first member is positioned substantially adjacent the outer boundary of the stream of marking particles and is spaced from the transport member. The channel also includes a second member connected to the first member and a third member connected to the second member. The second member is positioned adjacent the transport member and is spaced from the stream of marking particles. Substantially all the stream of air being directed by the first member is sequentially directed by the second member and the third member.

An agglomerate removal device for removing unwanted particles from images on a photoreceptor includes vacuum pick off source and baffles that create a controlled aerodynamic drag under the photoreceptor before the images reach a transfer station. Removing the agglomerates improves the quality of images transferred at the transfer station to receiving substrates.

A top vacuum corrugation feeder employs a vacuum feedhead working in conjunction with an air knife to feed sheets from the top of a stack. The air knife employs a thick boundary layer of air at a low pressure to suspend and separate the sheets by aerodynamic drag, resulting in about a 50% reduction in the required power for operation of conventional top vacuum corrugation feeders.
