摘要:
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 removable media tray for an image forming apparatus includes a housing, an exit port in the housing, a primary media stack, and a multi-purpose tray (MPT) input. Within the tray are first and second pick mechanisms operative to select a media sheet from the primary stack or MPT stack, respectively, and move the media sheet to the image forming apparatus through the exit port. A motor is disposed within the tray housing, and first and second drive assemblies operatively connect the motor to the first and second pick mechanisms, respectively. The motor drives the first pick mechanism forward by rotating in one direction, and drives the second pick mechanism forward by rotating in the opposite direction. A media sensor in the exit port senses media sheets from a variety of sources, including the primary media stack, the MPT stack, a duplex return path, or a large-capacity media sheet supply.

A door assembly movably positioned to a body of an image forming device. The door assembly includes a first frame and a second frame. The first frame is movably attached to the body, and the second frame is movably attached to the first frame. The movable connections between the frames and the main body cause accurate locating of a photoconductive member mounted on the door assembly within the body. In one embodiment, a contour surface within the body contacts the second frame to locate the second frame within the body. Methods of moving the door assembly are also disclosed including moving the door assembly from an open orientation that is spaced from the body, to a closed orientation that is in proximity to the body. The movement of the door assembly causes interaction between the frames and the body to accurately locate the second frame.

An image forming device with one or more door assemblies that engage locking mechanisms to secure a module in an operating position. The module may be coupled to one of the one or more door assemblies. A first locking mechanism may secure the module to the image forming device body when a first door assembly is closed. A second locking mechanism may secure the module to the body with a greater securing force than the first locking mechanism to secure the module to the body. The second locking mechanism may be engaged upon closing a second door assembly. Separate biasing members may be used to apply the securing forces. The locking mechanisms may comprise four-bar or over-center mechanisms to apply the securing forces.

In an image forming apparatus containing a plurality of rollers disposed with generally parallel axes, a retraction plate containing a plurality of rotational couplings is movable between engaged and retracted positions. Each rotational coupling is operative to transmit a rotary force to each cartridge when the retraction plate is in the engaged position. The couplings move laterally in an axial direction of the rollers as the retraction plate moves between the engaged and retracted positions, in response to an applied force. In one embodiment, the retraction plate is rotated about a pivot point to move the couplings between engaged and retracted positions. In another embodiment, the retraction plate is translated laterally in the axial direction of the couplings.

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.
摘要:
Devices and methods for directing a media sheet along a media path within an image forming apparatus. The media path comprises rollers that form a media nip, one or more deflectors, and a transport belt. The media nip conveys the media sheet along the media path into one or more deflectors. The one or more deflectors are positioned between the nip and the transport belt. The one or more deflectors control the angle of the media sheet as it approaches the transport belt and facilitates attachment of the media sheet to the transport belt. The transport belt then moves the media sheet past one or more image forming units and receives a toner image.

An image forming device determines a plurality of conditions in the device. In one embodiment, a signal source positioned downstream from a media input tray emits a signal. The signal reflects off of a reflective member and is received by a detector. Based on the amounts of the signal detected by the detector, a controller can determine a media input tray condition and a media sheet condition.

An image forming device having a body that receives a removable media input tray. The media input tray comprises a manual feed section and an input tray section each for feeding a media sheet to an aligner nip. The manual feed section includes a channel through which a user slides a media sheet into a main media path. The input tray section includes a space for holding a stack of media sheets that are individually picked and moved into the main media path.
