A method for dynamically lifting an elevator includes picking a sheet from a stack to feed to a media process where the stack is on a platform that can be lifted by an elevator, performing the media process, sensing a top of the stack to detect presence or absence of the stack at a media home position, sensing the top of the stack to detect presence or absence of the stack on the platform, sensing the platform to detect its presence or absence at a maximum elevator level, and indexing the stack at least once by lifting the platform through a given distance, during the media process and not during picking a sheet, unless presence of the top of the stack at the media home position is sensed or absence of media sheets on the elevator platform is sensed or presence of the elevator platform at the maximum elevator level is sensed.

A media handling system includes a platform, a bin supporting the platform below and for undergoing movement toward and away from a sheet feeding position, a first motion transmitting assembly coupled between the platform and bin and tailored to counterbalance the weight of the platform and any stack such that as the weight decreases the platform is lifted toward the sheet feeding position to maintain the stack top below a lower limit position thereof, a control mechanism to sense the position of the stack top relative to a given range between the lower limit position to an upper home position, and a second motion transmitting assembly drivingly coupled to the platform via the first motion transmitting assembly and responsive to the control mechanism sensing to cause the first motion transmitting assembly to further lift the platform to and maintain the stack top position within the given range.

A media handling system for an image forming machine includes a stationary frame, a platform supporting a stack of media sheets thereon, a bin supporting the platform and in turn supported on the stationary frame for undergoing movement relative thereto between a first position in which the bin locates the platform below and aligned with a pick mechanism and movable relative to the bin toward and away from the pick mechanism and a second position in which the bin displaces the platform away from and out of alignment with the pick mechanism, and a motion transmitting assembly coupled between the stationary frame, platform and bin and operable to convert movement of the bin between first and second positions relative to the stationary frame into movement of the platform relative to the bin toward and away from the pick mechanism.

摘要:
The present application is directed to methods and devices for determining the presence of a module and presence of a media sheet in a media path using output signals from a single sensor in an image forming device. One embodiment includes a sensor which may be oriented in a variety of positions through interaction with the module and the media sheet. An algorithm may be used to determine the presence of the module in a module insertion path and presence of the media sheet in the media path based on the position of the sensor.

摘要:
A media retraction and recycler system for use with image processing devices such as automatic document feeders and printers that concurrently supports two media sheets for duplex printing or scanning in a partial overlapping configuration in a variable nip pressure exit roll assembly allowing use of a media path that is shorter than the total media length of the two media sheets to facilitate an increased throughput during duplex scanning or printing operations.
摘要:
A printer is provided including a reference edge, a fuser assembly, a cooling apparatus and a controller. The reference edge is adapted to be contacted by a substrate as the substrate moves along a substrate path through the printer. The fuser assembly includes a heat transfer member including a belt and a backup member. The cooling apparatus is adapted to move cooling air capable of cooling the fuser assembly. The controller is configured to activate the cooling apparatus after determining that a first end portion of the backup member opposite a second end portion of the backup member near the reference edge is at a temperature above a predefined first threshold temperature.
