Embodiment Construction

[0016] image 3 The carrier recovery apparatus of the wet electrophotographic printer of the present invention shown in includes a drying roller 220 for absorbing a liquid carrier from a photosensitive belt 140, a heating roller that contacts and heats the drying roller 220 and evaporates the absorbed liquid carrier. 230 , both the drying roller and the heating roller are rotatably installed in the recovery cavity 210 .

[0017] Since a plurality of heat exchange fins 211 are formed on the outer surface of the recovery chamber 210, some evaporated gas carriers can be deposited on the inner surface of the recovery chamber 210 by heat exchange with the surrounding air passing through the plurality of heat exchange fins 211. cool down. The cooling carrier collected from the inner surface of the recovery cavity 210 is then introduced into the cartridge 260 through the first recovery pipe 250 .

[0018] The recovery chamber 210 communicates with a cooler 280 through a supply line...

Abstract

A carrier recovery apparatus of a liquid electrophotographic printer includes a drying roller rotating in contact with a photoreceptor belt, for absorbing a liquid carrier from the photoreceptor belt, a heating roller for heating the drying roller, in contact therewith, and evaporating the absorbed liquid carrier, a manifold surrounding the drying roller and the heating roller, for accommodating the evaporated gas carrier, a sealing blade disposed in a gap between the drying roller and the manifold, a condenser for receiving the gas carrier from the manifold and condensing the same, a supply line for supplying the gas carrier in the manifold to the condenser, and a return line for supplying again residual gas carrier which is not condensed in the condenser to the manifold, wherein the gas carrier is condensed while circulating in a closed loop formed by the manifold, the supply line, the condenser and the return line.

Description

technical field [0001] This invention relates to a wet electrophotographic printer, and more particularly to an apparatus for recovering a carrier from a photosensitive belt. Background technique [0002] Electrophotographic printers such as laser printers or copiers can be classified into dry printers using powder toner and wet printers using developer solution, which is a combination of toner and Mixed with a liquid carrier such as NORPAN available from Exxon. In both electrophotographic printers, an electrostatic latent image formed on a photosensitive belt is developed by applying toner, and then the image is printed out through a transfer medium. [0003] figure 1 The conventional wet electrophotographic printer shown in includes a printing unit 10 for printing a predetermined image on conveyed printing paper, and a carrier recovery device 20 for removing a liquid carrier from a photosensitive belt 14 for recycling. [0004] The printing unit 10 includes an endless p...
