摘要:
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.
摘要:
A housing for the scan unit printhead of an imaging device. The housing is substantially bowl shaped having a plurality of mounting surfaces extending inwardly toward a central region of the housing. The housing is constructed from a metal composition. The scan unit includes a plurality of light sources and an optical assembly operatively coupled thereto. The housing mounting surfaces support components of the optical assembly using an adhesive, without additional mounting hardware.

The present application is directed to methods and devices for a locking mechanism to connect input components for use within an image forming device. Two or more input components are placed in a stacked arrangement. The locking mechanism of a first input component engages the locking mechanism of a second input component to connect the input components. The locking mechanism may be activated automatically when the input units are stacked.

An imaging apparatus having a printer frame, a media tray frame module disposed below the printer frame, and an anti-tip stability system including two alignment posts mounted substantially diagonally on the media tray frame module. The alignment posts have first surfaces and second surfaces where each second surface makes an acute angle ranging from about 10 degrees to about 20 degrees with a horizontal plane. The alignment posts provide anti-tip stability to the imaging apparatus by engaging with the printer frame when the printer frame is tilted at a first contact angle with respect to the alignment posts due to the application of an external force. The alignment posts also facilitate relatively easy separation of the printer frame from the media tray frame module.
摘要:
A media restraint device in an input tray of an imaging apparatus includes a movable partition including a primary section and a secondary section. At least one locking mechanism selectively locks the primary section to the input tray, and the secondary section to the primary section. The locking mechanism unlocks either the primary section or the secondary section when the other is at a predetermined position.
摘要:
A print media feeder apparatus suitable for use in an image-forming device is provided. The apparatus comprises an elevator tray holding a stack of print media connected to a housing by a transmission system. The housing comprises a hoist drum that is connected to one end of a shaft for connecting the housing to the transmission system. A spring enclosure encasing a spring is fixed on the other end of the shaft. The load of print media is transmitted to the hoist drum, from which it is further transmitted to the spring through the shaft. This results in the displacement of the spring and a corresponding vertical movement of the elevator tray to position the print media at the desired feeding level.

摘要:
A laser scan unit for an imaging apparatus, including an optical paths having a plurality of optical components for directing and focusing a light beam. A component mounting mechanism is employed having a first member which is substantially fixed and resistant to movement, and a second member having an end portion which flexibly moves in response to forces acting thereon that are generated by changes in temperature due to differences in thermal expansion between the component and the first and second members.
摘要:
A media picking mechanism includes a pair of transmission shafts rotating in opposite directions. A housing is mounted around the pair of transmission shafts such that the first transmission shaft and the second transmission shaft are positioned substantially equidistant from a centerline of the housing. During a media picking operation, the rotation of the first transmission shaft of the pair of transmission shafts provides a first moment to the housing and rotation of a second transmission shaft of the pair of transmission shafts provides a second moment to the housing, which is equal and opposite to the first moment such that a net moment on the housing is near zero minimizing twisting of the housing. The two transmission shafts rotating in opposite directions, also results in substantially equal normal force to be applied by the first and second pick tires on the media.
