Welcome to brain 6 00:00:17,400 --> 00:00:20,680 Speaker 1: Stuff from how stuff works dot com where smart happens. 7 00:00:28,480 --> 00:00:31,720 Speaker 1: Hi'm Marshall Brain with today's question, how does an ink 8 00:00:31,800 --> 00:00:35,839 Speaker 1: jet printer work? An inkjet printer is any printer that 9 00:00:35,960 --> 00:00:39,640 Speaker 1: fires extremely small droplets of ink onto paper to create 10 00:00:39,680 --> 00:00:41,960 Speaker 1: an image. If you've ever looked at a piece of 11 00:00:42,000 --> 00:00:44,519 Speaker 1: paper that's come out of an inkjet printer, you know that, 12 00:00:44,680 --> 00:00:48,600 Speaker 1: first of all, the dots are incredibly small, thirty dots 13 00:00:48,640 --> 00:00:52,720 Speaker 1: per millimeter or more, and the dots are positioned very 14 00:00:52,760 --> 00:00:56,800 Speaker 1: precisely on the paper. Different types of inkjet printers form 15 00:00:56,880 --> 00:00:59,600 Speaker 1: their droplets of inc in different ways, but by far 16 00:00:59,680 --> 00:01:02,880 Speaker 1: the most popular technique is the bubble jet. In a 17 00:01:02,960 --> 00:01:07,240 Speaker 1: bubble jet printer, tiny resistors create heat, and this heat 18 00:01:07,480 --> 00:01:10,880 Speaker 1: vaporizes ink to create a bubble. In other words, the 19 00:01:10,920 --> 00:01:13,440 Speaker 1: ink is turning to steam and creating a bubble. In 20 00:01:13,480 --> 00:01:17,319 Speaker 1: the process. The expansion that creates the bubble, causes a 21 00:01:17,440 --> 00:01:20,720 Speaker 1: droplet deform, and then it dejects from the print head. 22 00:01:21,080 --> 00:01:24,440 Speaker 1: A typical bubble jet print head has sixty four or 23 00:01:25,319 --> 00:01:28,320 Speaker 1: eight tiny nozzles, and all of them can fire a 24 00:01:28,400 --> 00:01:32,520 Speaker 1: droplet simultaneously. This allows an inkjet printer to print on 25 00:01:32,560 --> 00:01:36,200 Speaker 1: an entire sheet of paper extremely quickly, even though the 26 00:01:36,280 --> 00:01:40,399 Speaker 1: dots are so small.
