Abstract
A melting device for melting an ink unit used in an inkjet printer, including a melting chamber provided with a wide end for dispensing the ink unit to the melting chamber and a narrow end, the melting chamber having a form such that the ink unit moves, as a result of melting, in a direction from the wide end to the narrow end, the ink unit being laterally enclosed with respect to said direction by one or more walls of a melting chamber, wherein the walls which form a lateral enclosure for the ink unit are heated, during the melting, to above a temperature at which the ink is liquid.
Claims12
A combination of a solid ink unit for use in an ink jet printer and a melting device for melting the ink unit, said melting device comprising a melting chamber provided with a wide end for dispensing the ink unit to the melting chamber and a narrow end, such that during melting, the ink unit moves in a direction from the wide end to the narrow end, wherein dimensions of the ink unit are adapted to the dimensions of the melting chamber such that the ink unit, when dispensed in the melting chamber, is laterally grasped, with respect to the said direction, by one or more walls of the melting chamber, without being supported by a wall of the melting chamber in a plane substantially perpendicular to said direction, whereby, during the melting of the said ink unit, each of said one or more walls is heated to a temperature where the ink is a liquid.
An inkjet printer containing at least one print head, said printhead being provided with a combination of a solid ink unit and a melting device for melting the ink unit, said melting device comprising a melting chamber provided with a wide end for dispensing the ink unit to the melting chamber and a narrow end, such that during melting, the ink unit moves in a direction from the wide end to the narrow end, wherein dimensions of the ink unit are adapted to the dimensions of the melting chamber such that the ink unit, when dispensed in the melting chamber, is laterally grasped, with respect to the said direction, by one or more walls of the melting chamber, without being supported by a wall of the melting chamber in a plane substantially perpendicular to said direction, whereby, during the melting of the said ink unit, each of said one or more walls is heated to a temperature where the ink is a liquid.
