=Computer Printer (Inkjet)=

Purpose
//To print pages and work papers that are on your computer.//

Energy
//Thermal Bubble: 1. In a "bubble jet" printer tiny little resistors create heat which then vaporizes the ink. 2. When the ink vaporizes it creates a bubble that pushes out small amounts of ink through a nozzle (there are usually about 300-600 nozzles) that goes onto the paper. 3. The bubble pops, causing more ink to be pulled out of the cartridge and into the print head. 4. The process starts over again.

Piezoelectric: 1. A tiny crystal located in the back of every nozzle receives an electric charge that causes it to vibrate. 2. When the crystal vibrates inward a drop of ink is pushed out of the nozzle. 3. When the crystal vibrates out, the ink that was sprayed out is replaced by more ink that is pulled into the nozzle. 4. The process starts over again.//

Controls
//The inkjet printer is controlled a system board which controls the printing process by sending the paper from the computer to the printer itself. allowing it to print the paper that is exactly on your computer screen.//

Materials
//Print head, Ink cartridges, Print head stepper motor, Belt, Stabilizer bar, Paper tray/feeder, Rollers, Paper feed stepper motor, Power supply, Control circuitry, Interface port(s)//

Science
//What is scientific principle is central to its operation? The inkjet printer is operated by dropping tiny little droplets of ink onto the paper to form different letters and characters. the inkjet printer uses one of the three main technologies including thermal, piezoelectric, and continuous//

Competitors
//Some competitors of the inkjet laser printer are the Sam-sung ML-2525 wireless laser printer and any other laser printer. As well as the Epson Stylus NX515 (printer/scanner/copier). Also any other printer that is out on shelves anywhere like Best Buy.//

Siblings
//some other devices that have the same scientific principles are laser printers.//

Element
In the inkjet laser printer one main thing in the printer is actually the ink.
