A method and apparatus is disclosed for maintaining the fluid level in a sump constant; that is, for maintaining the level constant relative to the height of the wick above the sump. As shown in the figure, a wick 10 has an end 12 thereof immersed in silicone oil 14 contained in a sump 16. The oil 14 serves as a release agent or separating fluid to be wicked to the surface of a heated fuser roll 18. For this purpose, another end 20 of the wick 10 engages the heated fuser roll surface. The level 22 of the oil is maintained constant relative to the wick 10 by automatic movement of the sump 16 upwardly as the oil is depleted. To this end an arm 24 of the sump is pivoted as indicated at 26 and a spring 28 biases the arm and therefore the sump in an upward direction. Accordingly, as the level of fluid moves downwardly in the sump, the sump moves that amount in the upward direction.
