摘要:
A system for heated gas fusing of toner on non-porous substrates is provided. The system uses (1) an extended fusing zone held at lower temperatures than needed for a roll nip or radiant fuser, and (2) a very low melt toner which can be fused at greatly reduced temperatures compared to conventional toners. In one form, the system is realized through (a) the use of heated gas as the low temperature extended zone fusing technology, and (b) the use of ultra-low melt (ULM) toner—which requires significantly reduced temperature compared to conventional toner. On non-porous packaging substrates the use of heated gas can limit the substrate temperature to 100° C.

摘要:
A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.

摘要:
A printer has a print head arranged to jet molten ink onto a surface, a transfix surface arranged to provide the surface for the print head, the transfix surface having a core and an outer shell of a predetermined grade of aluminum arranged on the core, the outer shell forming the surface for the print head. The printer also has a transport subsystem to transport a print substrate past the transfix surface such that the molten ink transfers from the transfix surface to the print substrate.
摘要:
Methods of leveling ink on substrates and apparatuses useful in printing are provided. An exemplary embodiment of the methods includes irradiating ink disposed on a surface of a porous substrate with radiation emitted by at least one radiant energy source. The radiation heats the ink to at least a viscosity threshold temperature of the ink to allow the ink to flow laterally on the surface to produce leveling of the ink. The ink is heated sufficiently rapidly that heat transfer from the ink to the substrate is sufficiently small during the leveling that ink at the substrate interface is cooled to a temperature below the viscosity threshold temperature thereby preventing any significant ink permeation into the substrate.
