Abstract: A fuser entrance guide in an electrophotographic apparatus, which supports a sheet of copy medium as it enters the fuser section. The guide has a curved base plate that has vacuum ports both at the edges and across the central area thereof. The ports in the central area are arranged in rows with the exits of all ports in a respective row being fluidly connected by a groove formed in the lower surface of the base plate. The recessed area of the grooves reduce the total contact area of the sheet thereby reducing the drag forces on the sheet but, at the same time, increasing the holding force of the vacuum on the sheet.

Abstract: An adjustable self-aligning tensioner, for a drive belt, the belt tensioner being self-aligning and readily adjustable. Such belt tensioner includes a pair of idler pulleys and a support for the pair of idler pulleys. A mount rotatably carries the idler pulley support. The mount is adjustably positioned relative to the drive belt, whereby the support carried by the mount locates the idler pulleys so as to be respectively engageable with the drive belt on opposite sides thereof. A mechanism reactive with the support and the mount urges the idler pulleys into engagement with the drive belt with a force so as to provide an adjustable preselected tension on the drive belt.

Abstract: A reproduction apparatus having a housing, a logic and control unit for controlling the operation of the reproduction apparatus, a user control interface for inputting control instruction signals to said logic and control unit, and a mechanism for mounting said user control interface so as to be usable by a variety of users. The mounting mechanism includes a user control interface support platform slidably supported for movement, relative to the reproduction apparatus housing to a home position and a position spaced from the home position where the user control interface is readily accessible by a user. The platform is automatically moved to its home position when a portion of the reproduction apparatus housing is opened to provide access to the interior of such housing.

Abstract: A cabinet for storing a computer keyboard includes a slidable tray with dust cover door. When the tray is slid to its open position providing access to the keyboard the dust cover door may be pivoted to an orientation wherein the inside of the door is positioned to support the wrists or hands of the operator.
