A self-contained alcohol purging and cleaning system for direct writing type trace recorders utilizes a source of compressed air, a tank of R-22 refrigerant and a tank of isopropyl alcohol. A main supply line tube may have its inlet port end selectively connected to either the source of the compressed air or the R-22 tank. The outlet port end of the main supply line tube is connected to the inlet port of the alcohol tank. A first elongated tubing member has its one end connected to the outlet port of the alcohol tank and its free output port end may be detachably connected to inlet end of an output hose whose outlet end is detachably connected to the ink supply manifold of a direct writing type trace recorder. By opening various valves of the system, pressurized gas passing through the main supply line tube forces the isopropyl alcohol into the ink supply manifold and out through its outlet ports until thickened ink is purged and the isopropyl alcohol flowing therefrom is reasonably clear. The output port end of the first elongated tubing member is then disconnected from the inlet end of the output hose and the output port end of a second elongated tubing member is detachably connected thereto. The inlet end of the second elongated tubing member is connected to the outlet port of the main supply line tube so that compressed gases may be used to purge any residual alcohol from the ink supply manifold. The manner for flushing aging and thickened ink from the analog pens would be similar to the steps used in flushing the ink supply manifold.
