Abstract: The dynamic range of an electrophotographic device may be shifted by calibrating a laser power of a laser source to operate within a first range of power levels during a laser power adjustment operation. At least one laser control parameter is modified after calibrating the laser power so that the laser source is operable within a second range of power levels different from the first range of power levels and a beam emitted by the laser source is controlled within the second range of power levels when the beam is directed towards an image area of a photoconductive surface.

Abstract: Upon initialization of an image-forming device, a sensor generates a signal to indicate the presence of packaging material at a location within the image-forming device. The image-forming device displays a message to a user responsive to this signal. The message may include a graphical representation of the image-forming device that graphically indicates access to the location. Upon user request, the image-forming device may also display instructions on how to remove the packaging material from the location. The instructions may also include a graphical representation of the location within the image-forming device, and text describing how to remove the packaging material from the location. The sensor generates another signal when it senses that the packaging material has been removed from the location. Once the packaging materials have been removed, the image-forming device completes the initialization procedure in preparation for image-forming operations.

Abstract: Methods and devices for moving media sheets through an image forming device. A sensor is positioned within an input area to determine a height of a media stack. When the media stack is full, a top-most sheet of the media stack is physically closer to the beginning point of the media path. When the media stack is depleted, the top-most sheet is positioned a further distance away from the beginning point. Movement of the media sheet is determined based on the height of the media stack. When the media stack is above a predetermined amount, the media sheet is moved according to a first algorithm. When the media stack is below the predetermined amount, the media sheet is moved according to a second algorithm.

A body (50) having major surfaces on each of opposite sides thereof, each having spaced strips (64) of superabrasive material, typically abrasive compact such as PCBN or PCD, for example, separated by a metal region or regions, such as cemented carbide, is provided. Each superabrasive strip of one major surface is arranged in register with a superabrasive strip of the opposite major surface. Alternatively, each superabrasive strip extends from one major surface to the opposite major surface. The body is severed from one major surface to the opposite major surface along at least two sets of planes intersecting at or in the respective superabrasive strips to produce the tool insert.

Abstract: An image forming device in a color printer or the like includes duplex printing. Multiple media sheets are moved through a media path which includes a primary path and a duplex path. Various parameters of the image forming device control the interpage gap between sheets. Parameters include peek-a-boo duplexing, sharing of motors within the drive rollers, and sharing of power supplies.

Abstract: Methods for moving a media sheet through the media path of an image forming device. In one embodiment, the media sheet may be moved by a pick mechanism having a pick roll from an input tray. The pick roll in the input tray may maintain contact with the media sheet and drive the sheet at a first elevated speed as it moves towards the nip. The pick roll may then slow as it brings the leading edge into contact with the nip. This slower speed may reduce the amount of nip shock or compression that may cause reengagement of the pick mechanism and an unintentional double sheet feed. Moving the media sheet at the fast speed a majority of the distance along the media path between the input tray and nip may increase media throughput.

Abstract: The automatic vent damper has various embodiments of a wind actuated vent system, which automatically closes to preclude entry of wind blown water when a wind of predetermined velocity and direction acts upon the device. The damper may be installed as an off-ridge or ridge vent system, or in other operating environments and installations as desired. Various mechanisms are used to operate the device, with all including one or more springs, which hold a rigid door or flap, open in light wind conditions. However, when a wind of sufficient velocity blows toward the vent opening, the door or flap is closed due to aerodynamic forces thereon to preclude entry of wind blown water into the device. The door or flap automatically opens again due to the spring mechanism when the wind abates.
