Speaker 1: Hi'm Marshall Brain with today's question, how does an ink
Speaker 1: jet printer work? An inkjet printer is any printer that
Speaker 1: fires extremely small droplets of ink onto paper to create
Speaker 1: an image. If you've ever looked at a piece of
Speaker 1: paper that's come out of an inkjet printer, you know that,
Speaker 1: first of all, the dots are incredibly small, thirty dots
Speaker 1: per millimeter or more, and the dots are positioned very
Speaker 1: precisely on the paper. Different types of inkjet printers form
Speaker 1: their droplets of inc in different ways, but by far
Speaker 1: the most popular technique is the bubble jet. In a
Speaker 1: bubble jet printer, tiny resistors create heat, and this heat
Speaker 1: vaporizes ink to create a bubble. In other words, the
Speaker 1: ink is turning to steam and creating a bubble. In
Speaker 1: the process. The expansion that creates the bubble, causes a
Speaker 1: droplet deform, and then it dejects from the print head.
Speaker 1: A typical bubble jet print head has sixty four or
Speaker 1: eight tiny nozzles, and all of them can fire a
Speaker 1: droplet simultaneously. This allows an inkjet printer to print on
Speaker 1: an entire sheet of paper extremely quickly, even though the
Speaker 1: dots are so small. For more on this and thousands
Speaker 1: of other topics. Because it how stuff works dot Com,
