device 130 to output tray 150 so that they can be reused with printer 120 optionally papers that fail the erasing process for example if they are torn or damaged so that they cannot be reused will be output to a different tray in some embodiments of the disclosure the ablation process may be performed by other methods for example a heater unit that heats the entire page or a light source e g a high energy light source that heats the entire page optionally a laser light beam with a wavelength of 355 nm 532 nm or 1064 nm or wavelengths with values in between these values or a combination of wavelengths can be used in an exemplary embodiment of the disclosure the laser beam illuminates points on the paper with a fluence of 1 6 j cm 2 or higher alternatively a lower intensity beam may be used for longer time durations to heat the paper to a desired temperature optionally different wavelengths and fluences may used for different colors and or different types of inks toners in an exemplary embodiment of the disclosure erasing paper 110 may be done either by a broad beam laser light covering the entire sheet surface or a portion of the sheet surface or a spot specific scanning laser optionally multiple scans with the laser beam may be performed to ensure erasing in an exemplary embodiment of the disclosure every point on paper 110 may.
