Abstract

Release oil (I) is applied to the fuser roll (2) of a xerographic copying machine by a two-part wick (3,4) which will avoid excessive oiling of the first copy. On part, the contact wick (3), remains in contact with the roll (2) at all times and the other, the supply wick (41, can be brought into contact with the contact wick during run mode or as desired by means of a camming mechanism indicated at (5). Thus, the supply wick alone becomes saturated during standby and the oil level in the contact wick will equilibriate but not saturate. The system lends itself to the insertion of an impedance such as a perforated membrane (6) between wicks to modify the supply characteristics if desired.

Release oil (I) is applied to the fuser roll (2) of a xerographic copying machine by a two-part wick (3,4) which will avoid excessive oiling of the first copy.

On part, the contact wick (3), remains in contact with the roll (2) at all times and the other, the supply wick (41, can be brought into contact with the contact wick during run mode or as desired by means of a camming mechanism indicated at
(5). Thus, the supply wick alone becomes saturated during standby and the oil level in the contact wick will equilibriate but not saturate. The system lends itself to the insertion of an impedance such as a perforated membrane (6) between wicks to modify the supply characteristics if desired.

On disconnection of the supply at the interface between the two parts of the wick, the supply wick (4) will be uniformly saturated whereas the contact wick
(3) will be uniformly charged with the contained oil that has equilibriated during running conditions. On reconnection, the contact wick wil I buffer the saturated supply wick, thereby limiting surges at start up after periods of dormancy.
