Abstract: Some embodiments provide a document viewing application with first and second document-browsing modes. The first document-browsing mode, accessed through a first UI item of several top-level UI items, displays several selectable document channel items corresponding to previously-selected document channels. Selection of one of the selectable document channel items causes the document viewing application to present a set of documents related to the document channel corresponding to the particular selectable item. The second document-browsing mode, accessed through a second UI item of the several top-level UI items, displays several selectable document panes corresponding to documents related to several of the previously-selected channels.

Abstract: A media stiffness sensor assembly for an imaging device. The assembly comprises a translation mechanism coupled to a contact member, a drive mechanism coupled to the translation mechanism and a position sensor for providing a signal indicative of the position of the contact member. The assembly is mounted within an imaging device so that the contact member is moved into bending contact with a cantilevered portion of a media sheet in the media path. The energy used to translate the contact member from a home position into the cantilevered portion of a media sheet in the media path to deflect the cantilevered portion is used to determine a weight of the media sheet.

Abstract: A method of determining a media weight using a media stiffness sensor in an imaging device. A media sheet is staged having a cantilevered portion which is deflected by a contact member translated into the cantilevered portion. Based on the energy used to move the contact member through a travel distance, a media weight can be determined. An operating parameter of the imaging device may be adjusted based on the media weight that was determined.

Abstract: The present application is directed to systems and methods to control access to an interior of an image forming device. The image forming device may include a body with a door that is movable between open and closed positions. In the open position, access is gained to an interior of the body. A controller controls a latch through a motor arrangement to lock and unlock the door. A user interface may be positioned on an exterior of the body to allow a user to enter commands to lock and unlock the door. Additional elements may also be included within the interior of the image forming device and operated with the motor arrangement.

Abstract: The application includes various embodiments of devices and methods for mounting a motor within an image forming apparatus. The motor is mounted on a frame and positioned to engage and drive a component within the image forming apparatus. In one embodiment, the component is an imaging unit. The frame includes an opening to receive the motor. A locating member is attached to the frame and extends into the opening to contact the motor and provide accurate positioning for engagement with the component. The locating ring provides for a press fit with lower forces. Additional fasteners may fixedly connect the motor to the frame and maintain the accurate positioning provided by the locating member.

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: Liquid laundry detergent compositions are provided that show remarkable performance even though they utilize only eco-friendly ingredients and have a sustainability index of greater than 3. Some embodiments include a liquid laundry detergent composition comprising alkyl polyglycoside (APG) with fatty alcohol sulfate, at least two detersive enzymes, an enzyme stabilization system (e.g. borate and/or citrate and/or calcium salts), d-limonene or other natural essence, water and adjuvant. In another exemplary embodiment, APG is combined with fatty acid soaps, at least two detersive enzymes, an enzyme stabilization system (e.g. borate and/or citrate and/or calcium salts), d-limonene or other natural essence, water and adjuvant. Such compositions show remarkable performance, good viscosity, physical storage stability, enzyme stability, and have a sustainability index of greater than 3.

Abstract: A unique eco-friendly liquid laundry detergent enhanced with natural essence and further comprising non-petroleum source anionic and nonionic surfactants, naturally occurring builders, and optional enzymes, to yield remarkably effective yet environmentally responsible detergents.

Abstract: Alignment nip regulation may be implemented by controlling the approach of media to an alignment nip. Where media is fed from a plurality of sources and from a plurality of approach angles through a common alignment nip, nip entry may be controlled by focusing the media through a diverter or a jog in an existing path to alter the course followed by the media sheets. The diverter may be configured to direct the media sheets to a contact point at or near the alignment nip, such as on a roller that forms the alignment nip. Alternatively, media sheets arriving at the nip from separate conduits may be separately directed to a common contact point near the alignment nip. In either case, one or more sensors may detect the approach of the media sheets at a time when the sheets are a common, predetermined distance away from the alignment nip.

Abstract: A color electrophotographic printing machine has a drive system which includes a frame and first, second and third motor-and-gear-train configurations mounted thereon at a common location and respectively drivingly coupled to first, second and third combinations of multiple color developer drive assemblies, multiple color photoconductive drum drive assemblies, a black developer drive assembly and a black photoconductive drum drive assembly so as to operate the same. The first and second configurations are operable at first and second motor gear mesh frequencies that are different and the third configuration is operable at a motor gear mesh frequency that can be substantially the same as one of the first and second motor gear mesh frequencies.

Abstract: The present application is directed to methods and devices for controlling a motor in an image forming device by sensing the amount of current applied to the motor. One embodiment includes a power supply operatively connected to a controller. The power supply provides an electrical current to a motor, and the amount of current is measured. The controller monitors the amount of current and determines an operating condition of the motor based on the current. The controller may then continue to allow the power supply to provide the electrical current to the motor, or may shut off the current based on the operating condition. The controller may also monitor a timer to determine how long the power supply has provided current to the motor. In one embodiment, the controller may use both the signal and monitored time to determine the operating condition of the motor.

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.
