Abstract:
Es werden Verfahren zum Höhenausgleich von Tinte auf Substraten und Vorrichtungen, die zum Drucken geeignet sind, bereitgestellt. Eine anschauliche Ausführungsform der Verfahren umfasst das Beaufschlagen von Tinte, die auf einer ersten Oberfläche eines porösen Substrats aufgebracht ist, mit Strahlung, die von mindestens einer Blitzlichtleuchte abgegeben wird. Der Strahlungsblitz erwärmt die Tinte auf mindestens eine Viskositätsschwellwerttemperatur der Tinte, so dass die Tinte lateral auf der ersten Oberfläche fließen kann, so dass ein Höhenausgleich der Tinte erreicht wird. Die Tinte wird ausreichend rasch erwärmt, so dass eine Wärmeübertragung von Tinte auf das Substrat ausreichend gering ist während des Höhenausgleichs, so dass Tinte an der Substratgrenzfläche auf eine Temperatur unterhalb der Viskositätsschwellwerttemperatur abgekühlt wird, wodurch ein merkliches Eindringen von Tinte in das Substrat von der ersten Oberfläche aus verhindert wird.
Abstract:
A heater panel is configured to heat a print medium in a printer. The heater panel includes electrical conductors that form a plurality of heating zones to emit radiant energy toward the print medium. Heating zones that correspond to edges of the print medium emit radiant energy with a greater power density than heating zones that correspond to central portions of the print medium. The heater panel has a plurality of angled positions to vary the view factor for high gain control.

PROBLEM TO BE SOLVED: To detach paper from a fixing member using an air knife under the optimum conditions. SOLUTION: A software means 550 contains a software object 560 which determines a first angle (ϕ), a second angle (θ), a distance (d), and a pressure of the air knife, when compiled. The software means 550 can be also used for generating a set of commands for performing front edge acquisition and positioning the air knife 250 at an optimum position for a medium and a fixing roll. A storage device concretely holds an object or a module for determining an optimizing parameter if given with an acquired setoff parameter from a user or a detection device. When software determines the optimizing parameter, a control signal 50 is generated so that the air knife 250 may be positioned at the optimum position of the job and the medium adopted by the job.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of leveling an ink on a substrate, and apparatus that is useful in printing and can generate quality printed images on many kinds of substrates.SOLUTION: The method includes a step of irradiating the ink 144 disposed on a first surface of a porous substrate 140 with radiation 122 emitted by at least one flash lamp. The radiation flash 122 heats the ink 144 to at least a viscosity threshold temperature of the ink 144 to allow the ink 144 to flow laterally on the first surface to produce leveling of the ink 144. The ink 144 is heated sufficiently rapidly, heat transfer from the ink 144 to the substrate is sufficiently small during the leveling, the ink 144 on a substrate interface is cooled to a temperature below the viscosity threshold temperature, thereby preventing any significant ink 144 permeation into the substrate 140 from the first surface.

Abstract:
PROBLEM TO BE SOLVED: To provide a carrying device capable of coping with a problem in a conventional carrying device wherein a sheet discharged from a fusing station is hot. SOLUTION: A carrying channel 32 is formed to feed a sheet S from a place where a sheet temperature is high in a copying machine to another place on the downstream side of the place. Several air drag coolers 10 are installed in the carrying channel 32, and its plenum 14 is connected to an air flow source through an inlet manifold 20. The air drag coolers 10 are allowed to communicate with the carrying channel 32 through an opening, for example, a slot 26 extending along the crosswise direction of the sheet in the carrying direction disposed between the inlet and the outlet of the sheet carrying channel 32. The sheet S fed into the carrying channel 32 is first fed along the sheet carrying direction and cooled by an air flow fed into the carrying channel 32 by the air drag coolers 10 through the slot 26.
