The presently described embodiments comprise a system that includes a
color changing medium, an erasing device using heat or long wavelength
infrared light as the erasing source, a writing device that can imagewise
apply a UV light to write the image on the media, and a transport to
transport the media along a paper path to be seen by the erasing device
and the writing device. The system could also function in an alternative
way. The image could be "erased" to the all dark state using light (e.g.
ultraviolet light) and then heated or illuminated using, for example,
infrared light in imagewise fashion to produce the image.
