Abstract
A toner fixing system for fixing toner onto a receiver medium includes a liquid-supply system for providing a heating liquid. A liquid-heating system warms the heating liquid to a temperature greater than the toner glass transition temperature. A liquid-delivery system impinges the warmed heating liquid onto a surface of the receiver medium so that heat is transferred from the warmed heating liquid to the toner. This raises the temperature of the toner to a level above the toner glass transition temperature.
Claims16
A toner fixing system for fixing toner onto a receiver medium, the toner having a toner glass transition temperature, comprising:
- a liquid-supply system for providing a heating liquid;
- a liquid-heating system for warming the heating liquid to a temperature greater than the toner glass transition temperature;
- and
- a liquid-delivery system for impinging the warmed heating liquid onto a surface of the receiver medium such that heat is transferred from the warmed heating liquid to the toner, thereby raising a temperature of the toner to a level above the toner glass transition temperature;
- wherein the liquid-delivery system includes a spraying system for spraying the warmed heating liquid onto the surface of the receiver medium.
A toner fixing system for fixing toner onto a receiver medium, the toner having a toner glass transition temperature, comprising:
- a liquid-supply system for providing a heating liquid;
- a liquid-heating system for warming the heating liquid to a temperature greater than the toner glass transition temperature;
- and
- a liquid-delivery system for impinging the warmed heating liquid onto a surface of the receiver medium such that heat is transferred from the warmed heating liquid to the toner, thereby raising a temperature of the toner to a level above the toner glass transition temperature;
- wherein the liquid-delivery system is a curtain-coating system that includes a slit through which the warmed heating liquid flows, thereby forming a liquid curtain which impinges on the surface of the receiver medium.
A toner fixing system for fixing toner onto a receiver medium, the toner having a toner glass transition temperature, comprising:
- a liquid-supply system for providing a heating liquid;
- a liquid-heating system for warming the heating liquid to a temperature greater than the toner glass transition temperature;
- and
- a liquid-delivery system for impinging the warmed heating liquid onto a surface of the receiver medium such that heat is transferred from the warmed heating liquid to the toner, thereby raising a temperature of the toner to a level above the toner glass transition temperature;
- wherein the liquid-delivery system includes:
- 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 lower surface of the receiver medium.
