Abstract: A fuser assembly includes a heated member and backup member forming a fusing nip. Nip loading springs on either ends of the fusing nip bias into contact the backup member and the heated member. Bellcranks contact the nip loading springs. Rotatable latches on either ends of the fusing nip act on the bellcranks to compress or relax the nip loading springs to open or close the fusing nip at respective distal or proximate ends of the fuser assembly. The rotatable latches are acted upon by corresponding latches of an access door of an imaging device that when opened provides access to the fuser assembly in an interior of the imaging device. The rotatable latches are independently movable. They can reside in different positions, yet allow closing the door of the imaging device.

Abstract: A fuser assembly includes a heated member and backup member forming a fusing nip. A nip loading spring biases into contact the backup member and the heated member. A bellcrank contacts the nip loading spring such that upon opening of an access door of the imaging device, the bellcrank acts on the nip loading spring to reduce a force between the backup member and the heated member but keeping in contact the backup member and the heated member. The bellcrank typifies a wire or other flexible lever. A cam pivots as the access door opens and engages the wire to compress the nip loading spring during use.

Abstract: A system having a processor is provided that facilitates drawing and annotation of objects on a touch screen. The processor is responsive to an object selection input corresponding to a selection of an object displayed at an object location, to display a preview type of an annotation for the selected object at an annotation location adjacent to the object location. Also, the processor stops displaying the annotation when an object deselection input is received that corresponds to a deselection of the object prior to the annotation being changed to a persistent type. Further, when the first object is selected, the processor is responsive to an annotation selection input corresponding to a selection of the annotation, to cause the annotation to change from being the preview type to being the persistent type that remains visually displayed when the object is deselected after the annotation has changed to the persistent type.

Abstract: A gutter guard apparatus and method of making the same is disclosed. In some embodiments, the gutter guard apparatus is made from at least two different types of materials, thereby enabling, for example, lighter weight, non-conductive plastics that are best suited for coupling to an existing rooftop gutter system in a corrosion preventing manner to be employed while at the same time providing for a central portion spanning the gutter opening made from a more durable material (e.g., lightweight expanded metals).
