It doesn't look so complex when you look at it however, when you open it up and undo it there is a different story.
The printing object is paper.
The paper grabber feeds a sheet of paper into the printer and there is a roller which advances the paper during printing. These cartridges and the black tubes make up the ink distribution system. This is the heart of the machine. The print head assembly fires ink droplets on paper. A belt then connects the print head assmebly to the motor. This cycle recoordinates the mechanics of printing and decodes information sent from the computer. Its job is to maintain a smooth relationship between the paper, print head and the axe. A single cartridge can fire nine hundred million droplets which is enough to print hundreds of pages. So how does the printer manage this technical feed. Four small motors play a major role. There is the motor that run the paper grabber. And another that feeds the sheet of paper into the printer. A third motor moves the print head assembly back and forth and crosses the paper. And another activates the ink pump.
These four motors coordinates to make things run smoothly.
The smooth operation really phase off when the print head comes into play. The head is made out of silicone and easily shaped and sculpted into the three thousand and nine hundred of tiny nozzles that fit onto the print head. A nozzle really works like a cattle. Inside, an electric current quickly heats up the tiny element. When it is super hot the ink boils and vaporizes and it expands. As it expands, it forces the droplet of ink out of the nozzle. The heating turns off a fresh new droplet from the cartridge rushes to refill the nozzle. This is a super fast paste system.
It happens incredibely fast hence, speed is everything and timing is very curicial.
Each and every single droplet must shoot approximately at the right moment to form the text and images on the page. As the print head skims about four hundreds of an inch job above the paper the printing circuit board orchestrates the ink shooting sequence so that the millions of individual droplets always hit their bulls eye.
