LEDs don’t need to be calibrated, and while a cold cathode tube has an operational life of 5-7 years, LEDs should last 8-10 years. The company says that LED light sources are more consistent than cold cathode, and do not change color or intensity during their life. While cold cathode is valued in the darkroom for its diffused light, the Epson ReadyScan LEDs used in these scanners are claimed to warm-up immediately so there is no waiting for the machine to make itself ready.Įpson is gradually shifting away from cold cathode in its scanners, with the V500 being the first to convert in 2007. With maximum scanning resolutions of 6400x9600dpi for film and 4800x9600dpi for prints, the principle difference in the new models from the old is the change from a cold cathode light source to LED. Replacing the Epson Perfection V750 and V700, which were introduced in February 2006, the Epson Perfection V850 and V800 will feature the same specification as the previous models, but will benefit from faster start-up and lower power consumption. Epson has announced a pair of high-end flatbed scanners that are capable of digitizing film in sizes of up to 10x8in.
