Xerox Demos Self-Erasing, Eco-Friendly Paper

Lucas123 writes "The same Xerox lab that brought us Ethernet, the GUI and the mouse has demonstrated paper that can be reused after printed text automatically deletes itself from its surface in a day. Instead of trashing or recycling after one use, a single piece of paper can be reused up to 100 times. 'The paper contains specially coded molecules that create a print after being exposed to ultraviolet light emitted from a thin bar in a printer. The ultraviolet bar itself is very small, so it can be used in mobile printers. The technology could also be useful for network printing.'"

My suspicion is that it isn't me at all, but rather that other people are only happy when they're bitching about something.

  66. "Reusable paper" by Anonymous Coward · · Score: 0

    Instead of trashing or recycling after one use, a single piece of paper can be reused up to 100 times. If the printer is anything like the Xerox printers I've used, it is very likely to jam with even slightly wrinkled paper, so this "reused up to 100 times" is more likely "reused a few times before it jams the printer and shreds itself." Sorry, but until printers can actually repair the paper before printing, this "reusable paper" theory turns out to be a complete bust in practice. What a rip!

  69. Light on chip internals by EmbeddedJanitor · · Score: 1
    Yes, light (of any sort) changes the thresholds etc of the gates (particularly the floating gates in flash memory). If you have an EPROM behaving like that then reprogramming will often make it better.

    I once had the inverse problem: a circuit that worked fine under normal light and crashed as soon as someone turned on the florescent lights. We at first thought it must be some poer surge thing and put scopes on the power etc etc. Eventually someone inadvertently covered the circuit and the problem went away, but scrashed as soon as we took the cover off. Of course the florescent tubes are actually blinking at 100Hz or so (double mains frequency) and that was causing a 100 Hz ripple on the gate thresholds, really screwing up memory accesses. Had us going for a while!

      No, the sale is of course not legal. Of course it will be harder to proof for the victim; OTOH an examination of the paper will probably add some credibility to his (true) version, because why on earth would you print the contract on this special paper, instead of using just normal paper (which probably is cheaper)?

      BTW, usually both parties get a copy of the contract, and how would you print the new text on the other copy (which you don't have)?
