Paper feed rollers 45 on both sides
The scrap toner suction unit 46 is disposed so as to face the driven roller portion of the polishing belt 41. While passing the recording paper 47 printed by the printer with the toner 48 between the rotating polishing belt 41 and the elastic roller 44, the printing toner 48 is scraped and erased. The scrap toner scraped off is collected by a suction unit 46 in a collection box (not shown). As an example of recording paper recycling conditions, a polishing belt containing diamond abrasive grains having an abrasive grain size of 1 μm is rotated at a traveling speed of 20 m / s by a drive roller. Then, the recording paper with print (the protruding height of the toner from the paper surface is about 10 μm) was passed between the rotary polishing belt and the elastic roller at a feeding speed of 15 cm / s by a paper feeding roller. The distance between the rotary polishing belt and the elastic roller is set so that the toner protrusion (about 10 μm) of the printed recording paper is erased.
Was adjusted using. In this case, the polishing belt contacted and moved on the toner of the printed recording paper at a speed of about 20 m / s to mechanically scrape the toner, and one A4 size paper could be regenerated in 2 seconds. Each polishing belt can reproduce tens of thousands of recording papers, can be easily replaced, and the running cost is low.
