rajendra-ranade (India) Tonerless plain paper laser printing A little elaborate concept is as below..... For calibration, the laser burns a small square blot at top left corner of the page at increasing power and with help of a sensor, burns it just enough black. And calibrates the laser for that paper (alternately, it can be precalibrated for standard grammage paper) Then it simply runs the machine. Afterall lasers can cut "corneas" (LASSIK sight correction) as well as diamonds. All the problems like safety etc have been solved there, and they may get solved here also. |
