An electrical device includes a housing having a mating end and a wire end. One or more contacts attach to the housing proximate the mating end. One or more conductor wires extending from the wire end and connect to the one or more contacts. A seal assembly connects to the housing proximate the wire end. The seal assembly is configured for movement between an opened position and a closed position. The seal assembly has an upper seal and a lower seal configured to mate along an interface in the closed position to limit the ingress of one or more environmental elements into the electrical device.

A photoconductor unit for an electrophotographic image forming device according to one example embodiment includes a housing and a photoconductive drum rotatably mounted on the housing. The photoconductive drum has an outer surface. A cap is detachably mounted on the housing. A lubricant supply is positioned to provide a lubricant material to the outer surface of the photoconductive drum. The lubricant supply is mounted on the cap such that detachment of the cap from the housing separates the lubricant supply from the housing permitting replacement of the lubricant supply independent of the photoconductive drum.

A cleaner assembly according to one embodiment includes a cleaner blade that extends upward in a cantilevered manner and that includes a cleaning edge for contacting a surface to remove toner from the surface. A waste toner sump is positioned adjacent to a rear side of the cleaner blade for storing toner removed from the surface by the cleaner blade. A film seal extends in a cantilevered manner toward the rear side of the cleaner blade and contacts the rear side of the cleaner blade along a longitudinal length of the cleaner blade. A foam seal is positioned between the rear side of the cleaner blade and the wall below the contact between the rear side of the cleaner blade and the film seal. The foam seal extends along the longitudinal length of the cleaner blade.

An imaging unit for an electrophotographic image forming device having positional control features for aligning the imaging unit in a supporting frame in the image forming device. The positional control features include on each end wall, first and second bullet noses and a stop arm positioned between the two bullet noses. The first and second bullet noses engage support or datum surfaces provided in corresponding openings in the frame. The stop arm receives a biasing force that rotates the imaging unit into its final operating position. A latching assembly is provided on one end wall to prevent the imaging unit from ejecting from the frame.

A removable unit for an electrophotographic imaging device includes a housing having an opening, a rotatable roll disposed near the opening and adjacent to a bottom of the housing and a blade assembly coupled to the housing. The blade assembly includes a support bracket secured to a wall defining at least a part of the opening of the housing, and a blade member coupled to the support bracket and being positioned in the removable unit so that a distal end portion of the blade member engages with the rotatable roll. The housing, the blade assembly, and a portion of a surface of the rotatable roll define a substantially sealed enclosure for containing toner therein.

A replaceable unit for an image forming device having features for aligning the replaceable unit when installed in the image forming device and to ensure alignment between the replaceable unit and a detachable unit attachable to the replaceable unit. End walls support a photoconductive drum and have a first bullet nose, second bullet nose and stop arm used for alignment of the replaceable unit in a frame of the image forming device. Support members are on a top surface of the bottom plate with a top planar surface of one of the support members forming a rotational stop and a datum surface for the detachable unit when attached. A mounting channel in one end wall provides a second datum surface for the detachable unit and a mounting channel in the other provides a deskewing plug to adjust axial alignment between the photoconductive drum and a roll in the detachable unit.

A toner container including a first electrode disposed within the toner container, a second electrode electrically connected to the first electrode and disposed within the toner container, and a sense electrode disposed between the first electrode and the second electrode. The sense electrode and the first electrode form a first capacitor having a first capacitance that changes in response to a change in toner amount existing therebetween. The sense electrode and the second electrode form a second capacitor having a second capacitance that changes in response to a change in toner amount existing therebetween.

Capacitive toner level sensor

A deskewing plug and assembly mountable in a frame having a first and a second shaft forming a nip therebetween with the second shaft rotatably mounted in a pair of opposed channels and biased toward the first shaft for adjusting the axial alignment of the shafts. The deskewing plug has a generally cylindrical body having first portion, a second portion and a tab portion. The second portion has a circumferential camming surface cooperatively engageable with the second shaft. Rotation of the plug and camming surface adjusts the axial alignment of the second shaft. The tab portion radially extends from the first portion and has radially extending ridges frictionally engageable with a wall of the opening in the frame to prevent rotation of the deskewing plug after adjustment. A cap may be provided to cover and frictionally engage the tab with the cap being fastenable to the frame.

A replaceable unit for an electrophotographic image forming device includes a housing having a photoconductive drum rotatably mounted thereon. The photoconductive drum has a rotational axis. A guide channel on an exterior of the housing extends parallel to the rotational axis of the photoconductive drum and is positioned to guide insertion of the housing into the image forming device. A positioning stop on the housing is movable between a latching position and an unlatching position. In the latching position the positioning stop obstructs at least a portion of the guide channel to limit the travel of the replaceable unit in the image forming device parallel to the rotational axis of the photoconductive drum. A release handle on the housing is operatively connected to the positioning stop to move the positioning stop from the latching position of the positioning stop to the unlatching position of the positioning stop.

A developer unit for use in an image forming device according to one example embodiment includes a housing having an inlet port for receiving toner, a sump for holding received toner and a developer roll rotatably mounted in the housing for transferring toner from the sump. A rotatable agitator is positioned in a lower portion of the sump and a pivotable agitator is positioned in an upper portion of the sump. A biasing member biases the pivotable agitator toward a stop in the pivot path of the pivotable agitator. The pivotable agitator includes an engagement feature positioned in the rotational path of the rotatable agitator when the pivotable agitator is in its home position. As the rotatable agitator rotates, the rotatable agitator engages and disengages the engagement feature causing the pivotable agitator to pivot away from and toward its home position.

The invention provides a wiping assembly in an image forming device, to clean at least one sensor lens in the image forming device. The wiping assembly includes a bracket to move between a first position and a second position across the sensor lens. Further, the wiping assembly includes a wiper to clean the sensor lens. The wiper is located between the bracket and a sensor housing, which supports the sensor lens. The wiping assembly includes a spring to actuate the movement of the bracket between the first position and the second position. The movement of the bracket is actuated by the movement of a print media tray and/or the movement of a toner cartridge.

Wiping assembly in an image forming device

An image forming equipment, e.g., a laser printer includes a photoconductive (PC) drum and an associated charge roller and incorporates a conductive polymer cleaner blade having an electrical potential to sufficiently charge contamination particles on the PC drum to electrically repel from a charged surface, such as the charge roller.
