Embodiments of a device to move waste toner within an image forming device. In one embodiment, waste toner is formed during the image formation process. The waste toner is captured and moved through a first conduit. The conduit includes an outlet for passing the waste toner to a second conduit. The door is positionable between an open orientation to allow the waste toner to discharge into the second conduit, and a closed orientation. The second conduit includes an inlet for receiving the waste toner. The interface between the first and second conduits allows for the door to move between the open and closed orientations. The interface also greatly reduces or prevents the waste toner from leaking as it passes from the first conduit into the second conduit.

The present invention is directed to an article, system and method for determining and/or selecting the location of a toner engaging member in a developing agent device such as a toner cartridge. The article, system and method may be applied to a printing device such as a laser printer.
摘要:
A toner feeding device and method to supply toner from a toner reservoir to a selected location in the printer such as a toner supply roll. The toner feeding device may contact with a portion of an inner wall of a toner reservoir and may flex and may subsequently recover to convey toner particles.

A toner fill plug for a toner cartridge within an image forming device. The cartridge includes a toner reservoir having a port through which toner is input. The plug is sized to fit within the port and prevent toner leakage. The plug includes a reflector which aligns with an adjacently-positioned toner level sensor for determining the amount of toner remaining within the reservoir. The plug is removable to allow the user to refill the reservoir with new toner.

An image forming device having a main body and a movable subunit. The subunit is movable between a first orientation and a second orientation. A developer member is positioned within the main body, and a photoconductive member is positioned on the subunit. In the first orientation, the developer member and photoconductive member are spaced apart. In the second orientation, the photoconductive member is positioned either in contact with or closely located to the developer member. Image formation occurs when the subunit is in the second orientation as toner is transferred from the developer member to the photoconductive member. Methods of using the image forming device include positioning the developer member in the main body and the photoconductive member on the subunit, and moving the subunit from a first orientation to a second orientation such that image formation can occur.

A toner layer regulating system for an electrophotographic image forming apparatus comprises a toner carrier; a metallic toner regulating member having a stress-strain curve prior to assembly with an elastic region, an inelastic region, and an initial yield stress value; and the toner regulating member supported in cantilevered fashion against the toner carrier so as to form a toner nip therebetween with an applied stress on the toner regulating member greater than the initial yield stress value. The metallic toner regulating member may comprise a metallic substrate and a coating thereon; the coating helping to form the toner nip. By deflecting the toner regulating member, when installed, by an amount that induces strains falling outside the elastic region of the corresponding stress-strain curve, the toner regulating system is less sensitive to geometrical variances.
摘要:
A waste toner removal system for an image forming device. The invention includes a mechanism for removing the waste toner from the cartridge and transporting it through a toner chute to a waste toner tank. One or more actuators within the device allow for the connection between the various elements to seal the waste toner path and prevent toner leakage. Methods of moving waste toner are also disclosed that include moving the waste toner through the cartridge and into a waste toner chute. The waste toner is moved through the chute and into a waste toner tank where it may be removed from the device.
摘要:
A gear unit comprising a shaft and a gear each having a first axial section and a second axial section. The first axial section features the gear having external teeth with an internal surface that corresponds to an external surface of the shaft. The second axial section includes features in the shaft and gear that engage together. Methods of using the gear unit including positioned the gear on the shaft, and rotating the gear relative to the shaft to engage the gear with the shaft.

A biasing mechanism in an image forming apparatus exerts a variable force on a removable cartridge unit to generate a nip force between a roller in the cartridge unit and another roller. A pivot member is fixed to the apparatus housing. An arm is pivotally mounted in the housing about the pivot member, with the arm in contact with a protrusion on the cartridge unit. A force generating member is mounted in the housing and contacts the arm so as to urge the arm to pivot about the pivot member and press against the cartridge unit. The resulting force exerted on the cartridge unit by the arm varies according to the point of contact between the cartridge unit and the arm. In some embodiments, the arm and the cartridge unit protrusion are electrically conductive, and an electrical contact is established as the arm is pressed against the protrusion.
摘要:
An apparatus and method for ink-jet printing onto an intermediate drum in a helical pattern while correcting for image skew and aliasing. A plurality of ink-jet print heads place an image on an intermediate drum, impervious to ink, in a helical patter. To compensate for helical printing, the image is altered by nozzle placement and image manipulation to correct for skewing errors, and thereafter, the nozzle timing is adjusted to correct for aliasing. The plurality of print heads move parallel to the axis of rotation of the drum while the drum is simultaneously rotating, causing the image to be placed in a helical pattern. Once the entire image is placed on the drum, paper is rolled against the drum under pressure and the image is transferred thereto.
