Patent ID: 8824944

Claim:
A method for fixing toner onto a receiver medium, the toner having a toner glass transition temperature, comprising: depositing a pattern of toner onto a surface of the receiver medium; bringing a surface of the receiver medium into contact with a heating liquid, the heating liquid being at a temperature greater than the toner glass transition temperature such that heat is transferred from the heating liquid to the toner, thereby raising a temperature of the toner to a level above the toner glass transition temperature, wherein the surface of the receiver medium is brought into contact with the heating liquid by using a liquid-delivery system to impinge the warmed heating liquid onto at least one surface of the receiver medium, the liquid-delivery system including: a tank supplied with warmed heating liquid; a wave-forming system that forms a stationary wave on a top surface of the warmed heating liquid in the tank; and a media-transport system that transports the receiver medium over the top of the warmed heating liquid such that peaks of the stationary wave impinge on a bottom surface of the receiver media.
