A media-transport system transports the moistened medium along a transport path which passes through the liquid reservoir. The moistened medium is submerged in the warmed heating liquid and heat is transferred from the warmed heating liquid to the moistening liquid. This vaporizes the moistening liquid and removing it from the moistened medium. | 04-17-2014 |
20140101965 | APPLYING HEATING LIQUID TO REMOVE MOISTENING LIQUID - A method for removing a moistening liquid from a moistened medium includes bringing at least one surface of the moistened medium into contact with a heating liquid. The heating liquid is warmed to a temperature greater than a moistening-liquid boiling point. Heat is transferred from the warmed heating liquid to the moistening liquid, thereby vaporizing the moistening liquid and removing it from the moistened medium. | 04-17-2014 |
20140101968 | REMOVING MOISTENING LIQUID USING HEATING-LIQUID BARRIER - A method for removing a moistening liquid from a moistened medium includes providing a liquid-blocking barrier having a first surface and a second surface that is impermeable to a heating liquid. A surface of the moistened medium is brought into contact with the first surface of the liquid-blocking barrier. The heating liquid is brought into contact with the second surface of the liquid-blocking barrier, the heating liquid being at a temperature greater than a moistening-liquid boiling point. Heat is thus transferred through the liquid-blocking barrier from the heating liquid to the moistening liquid, vaporizing the moistening liquid and removing it from the moistened medium. | 04-17-2014 |
20140104354 | BARRIER DRYER WITH POROUS LIQUID-CARRYING MATERIAL - A media drying system removes a moistening liquid from a moistened medium. A liquid reservoir containing a heating liquid heated above a moistening-liquid boiling point. A rotatable liquid-blocking member has a liquid-blocking layer with an inner surface and an outer surface. A media-transport system transports the moistened medium so it contacts or is entrained around the liquid-blocking member in a path zone so that the moistened medium is brought into contact with the outer surface of the liquid-blocking layer. A porous material absorbs heating liquid from the liquid reservoir and brings the absorbed heating liquid into contact with the inner surface of the liquid-blocking layer for at least a portion of the path zone. Heat is transferred through the liquid-blocking layer from the absorbed warmed heating liquid to the moistening liquid, vaporizing the moistening liquid and removing it from the moistened medium. | 04-17-2014 |
20140116650 | TONER FIXER IMPINGING HEATING LIQUID ONTO MEDIUM - 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. | 05-01-2014 |
20140119748 | TONER-FIXING DRUM CONTAINING HEATING LIQUID - A toner fixing system for fixing toner onto a receiver medium includes rotatable fixing drum partially filled by a heating liquid, so that a stationary-drum liquid level is defined. The heating liquid is warmed above a toner glass transition temperature. The fixing drum rotates fast enough to draw the heating liquid to substantially cover an inner surface thereof. The moving receiver medium contacts an outer surface of the fixing drum in a contact region above the stationary-drum liquid level. Heat is transferred through the rotating fixing drum from the drawn warmed heating liquid to heat the toner above its glass transition temperature. A sensor detects stoppage of the receiver medium in contact with the fixing drum. A controller automatically stops the rotation of the fixing drum when a stoppage is detected, so that the heating liquid is pulled by gravity away from the stopped receiver medium. | 05-01-2014 |
20140119790 | TRANSPORTED MEDIUM HEATING-LIQUID-BARRIER TONER FIXER - A system for fixing toner onto a receiver medium includes a reservoir containing heating liquid. A liquid-heating system warms the heating liquid to a temperature greater than a toner glass transition temperature. A rotatable liquid-blocking barrier has an inner surface and an outer surface. A media-transport system transports the receiver medium along a transport path. The transported receiver medium contacts or is entrained around the liquid-blocking member barrier so that the receiver medium is brought into contact with the outer surface of the liquid-blocking layer. The liquid-blocking barrier member and the reservoir are arranged so that an entrained portion of the receiver medium passes through the reservoir and is submerged in the warmed heating liquid, which contacts the inner surface. Heat is transferred from the warmed heating liquid to the toner, raising a temperature of the toner to a level above the toner glass transition temperature. | 05-01-2014 |
20140119791 | TONER FIXER WITH HEATING LIQUID IN CAVITY - A toner fixing system has a heating member rotatable around an axis.
