Abstract
In a purge apparatus for use with a color ink jet printer, a suction member that sucks a nozzle surface of an ink jet head is integral with a suction cap and a cap holder that receives the suction cap therein. A suction adapter to which a suction tube is connected is integral with the cap holder. An air-communicating adapter to which an air-communicating tube is connected is formed separately from the cap holder. The air-communicating adapter is loosely supported in the cap holder.
Claims22
