This newscast was somewhat misleading. At least one copy machine maker (Xerox) has DOD approved image overwrite protection that is available by simply setting a parameter. This effectively solves the issue of retained images of documents on the copier's disk drive. There is also a disk overwrite feature to cleanup the existing documents after the immediate overwrite parameter has been turned on. Since none of this is by default the newscast did a service by shining a light on the problem.
