International Classification:

G03G 15/00

US Classification:

399110

Abstract:

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 include four-bar or over-center mechanisms to apply the securing forces.

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B65H 3/06

US Classification:

271117, 271118

Abstract:

Assemblies and methods to move media sheets from a media stack within an image forming apparatus. These may include a pivoting arm with an attached roller that contacts the media stack and rotates to move a top-most sheet from the media stack. A clutch may be operatively connected to the arm for the arm to pivot in a first direction to maintain the roller positioned on a top of the media stack as the media stack is depleted and a height of the media stack is reduced. The clutch may also reduce movement of the arm in a second direction beyond a predetermined amount.

International Classification:

B65H 1/08

US Classification:

271147, 271160

Abstract:

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.

Lexmark International, Inc. - Lexington KY

International Classification:

B65H 3/44

US Classification:

271 911, 271 901

Abstract:

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.

International Classification:

B65H 1/08

US Classification:

271147, 187262, 2483301

Abstract:

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.

International Classification:

B65H 1/00

US Classification:

271171

Abstract:

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.

Abstract:

The present application is directed to methods and devices for aligning media sheets in an input tray of an image forming device. The input tray includes a support surface and at least two spaced apart side walls. A first side wall includes a reference surface to align the media sheets. A second side wall includes a plurality of biasing members. The biasing members bias the media sheets toward the reference surface.

US Classification:

271152, 271153, 271154

Abstract:

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.
