ABSTRACT:
This is a mechanical oil dispenser for use in applying an oil to the surface (or two surfaces in a duplex mode) of printed media to improve its sheet-handling characteristics. This dispenser system has an oil-containing housing or tank with oil ports at the bottom of the tank. The ports are abutting a wick, this wick then disperses oil to an applicator roll which in turn applies oil to one or both surfaces of a printed media. The oil ports and oil flow are controlled by the profile of a cam and shaft in operative connection to said ports. Opening and closing of these oil ports are controlled by a cam shaft movement actuated by the rotation and stopping of the applicator roll.
