The KX-MB2100 Series' Quick Duplexing can print out double-sided documents at a rate of 24 ppm, effectively cutting print time in half when compared to standard 26-ppm MFP duplexing. Because you only need half as much paper – or even just a 1/4 as much when 2-in-1 duplex is used – you'll need a lot less storage space. You'll also save plenty on consumables. With 2-in-1 duplex, you can slash paper consumption by as much as 75%, while cutting toner consumption in half. Printer operating time is also reduced, saving electricity cost.
