ABSTRACT:
The technology encompassed by the practice of this invention includes apparatus for ink jet printing under the control of electronic circuitry and ink jet printing under the control of an operator, for example, a typewriter. Broadly, the technology presented in accordance with the principles of this invention utilizes an ink eradicator which removes indicia of the ink by chemical reaction. The character of the eradicator fluid is such that another fluid may be utilized either together therewith or separately to neutralize the residue from the chemical reaction so that printing can readily be accomplished in the location where erasure has occurred. Specifically, practice of this invention is contemplated with means that applies the eradicator fluid over the location on a surface where printing has occurred by ink jet droplets as well as over an entire area thereon within which there is ink jet printing for which a change is to be achieved. For exemplary embodiments of this invention, the eradicator fluid is applied by a wick from a reservoir and the chemical reaction is enhanced by heating the location for the erasure by an external heating means.
