Abstract: An image development system for developing a latent image on an imaging surface, such as a xerographic photoreceptor, with plural development rollers having internal axially extending developer magnets with relatively offset axial end positions, and wherein at least one development roller has a smooth surface area at that same end, to reduce edge banding image defects from the interaction of the axial ends of the magnets of adjacent development rollers, especially for large size copy sheets being printed, such as B4 size. The image developer unit may have three development rollers with three different lengths of developer magnets to provide three different magnetic end positions staggered on opposite sides of the end position of the large sheet (relative to the imaging surface).

Abstract: A movable gate is provided adjacent an input position of a slotted rotatable disk for aiding in the insertion of sheets into the disk slot(s). The movable gate moves between a first position and a second position wherein the first position is closer to the disk than the second position. When in the first position, the movable gate contacts and directs the leading portion of a sheet into the disk slot. When in the second position, the movable gate does not contact the sheet. The gate is moved to the second position at least while the trailing portion of the sheet passes thereunder so that the sheet does not slow down after exiting a pair of input rollers located upstream thereof and so that the trailing portion of the sheet is free to contact an overhead trail edge transport belt.
