AIR CIRCULATION SYSTEM OF WET ELECTROPHOTOGRAPHIC TYPE PRINTER

摘要

PURPOSE: A wet electronic photographic type printer is provided to circulate an engine shell, an air sprayer and the air of a dry unit using one inlet. CONSTITUTION: In an air circulation system of a wet electronic photographic type printer, a first channel(710) is equipped to induce air inlet through an outlet(510) of an engine shell(50) to the outside through a filter(900). In the first channel(710), a return channel(730) branched to induce a flow of air to an air sprayer equipped in a developing unit(200) is connected and also a second channel(720) is connected met with the first channel(710) by way of a condenser(600) by inserting air from the dry unit(400). And an air pump(800) for inserting and erupting air is installed between points(P1) and (P2) where the second channel(720) and the return channel(730) are connected. The air circulation system is composed of a photosensitive medium(100), a squeegee roller(210) and a print unit(300). If the air pump(800) is operated, air is circulated at the same time along the first and the second channels(710,720) and the return channel(730).
