Abstract
An image forming apparatus includes a collection system for collecting vapor co-solvents that are a byproduct of liquid ink. In addition, the collection system collects dew condensation from the moist air that is generated by lamps that dry the ink on a substrate. The collection system can be located in an exhaust passage. A condenser is installed in parallel and in front of an exhaust fan in the exhaust passage. The exhaust fan directs a flow of air through the exhaust passage. The collection system also includes a removable waste bottle for collecting the dew condensation and the condensed co-solvents. The exhaust passage bifurcates into an exhaust duct that is located after the exhaust fan and which discharges dry air and a collection channel that is located in front of the exhaust fan and which carries liquid drip off to the removable waste bottle.
