Abstract: This invention involves a kit or cartridge useful in installing an endless belt into a belt-containing system such as a xerographic marking system. The cartridge has a sheath to house all of the components of the cartridge. These components are: a traveling roller having a turn handle or knob, a belt to be installed, gear racks on which the traveling roller will move; these would probably be located in the machine, internal cartridge rolls, and conduits in the internal cartridge rolls. The belt is looped around the traveling roll on one of its ends and wound around the internal cartridge rolls on its other end. The belt will unwind from around these internal cartridge rolls as the traveling roll moves away from these cartridge rolls.

Abstract: A method and apparatus are provided to control the atmosphere inside of a xerographic control module of an image forming device so that a dew point condition is not reached. The parameters of the atmosphere within the xerographic chamber which are controlled include pressure, temperature and humidity.

Abstract: A method and apparatus for maintaining the air pressure within a xerographic module/chamber of an image forming device above ambient pressure outside of the xerographic module/chamber which uses a pressure sensor, e.g., an altimeter to monitor ambient atmospheric pressure, and a microprocessor to control and maintain air pressure to a determined set point.

Abstract: Apparatus for transporting sheets in a longitudinal direction includes an improvement for reducing the imparting to the sheet material of friction, static charge, and foreign deleterious material while substantially minimizing the burnishing of the surface of the sheets. To this end, a plurality of elongated sheet supporting rib members project outwardly from a guide surface, extend diagonally relative to the longitudinal direction, are all of uniform height above the sheet guide surface, and are of uniform cross section. The sheet supporting rib members are so dimensioned and positioned that any random element of a sheet being fed in the longitudinal direction through the apparatus crosses only one of the sheet supporting rib members. Actually, a plurality of first sheet supporting rib members extend diagonally in a first direction and another plurality of elongated second sheet supporting rib members extend diagonally in a second direction which is transverse of the first direction.
