Abstract
The invention relates to a liquid dispensing apparatus suitable for use in the fuser of an electrostatographic recording machine such as, for example, a xerographic copier or a printer. The apparatus includes a trough (41), a wick (100) extending along its length and a roller (47) in contact with the wick (100). A metering blade (49) is located adjacent the roller (47) in such a manner as to scrape off excess liquid from the surface of the roller (47), the metering blade (49) being disposed relative to the wick (100) such that the excess liquid falls on the wick (100) thereby ensuring saturation of the wick (100). Return paths for the excess liquid are provided between the wick (100) and the wall of the trough (41) so as to prevent build up of the excess liquid above the wick (100).
