  • Device for applying release agent to the surface of a fixing roller of an electrographic printer or copier
    Patent number: 6070044
    Abstract: A printer or copier using transfer printing has a fixing drum for fixing toner on a medium, such as paper. Parting liquid, or release agent, is applied to the fixing drum using an application element, the application element being moved over the surface of the fixing drum as it is unwound from a supply roll and wound onto a take-up roll. The speed of the supply roll is sensed and the motor of the take-up roll is controlled so that the speed of the application element is constant regardless of changes in the diameter of the application element on the supply roll. The speed of the supply roll may be sensed with a magnet and Hall sensor arrangement.
