QUESTION 53 In common ink jet printers how is ink transferred to the page? (Choose two)
A. Pressure is built by boiling ink B. Pressure is applied by using a crystal C. Pressure is built by a motorized pump D. Screens deflect ink on the paper into the proper positions. E. Ink is sprayed on to the paper and managed by a nozzle. |
Answer: A, E Explanation: There are two basic inkjet techniques: Bubble jet: In a thermal inkjet printer, tiny resistors create heat, and this heat vaporizes ink to create a bubble. As the bubble expands, some of the ink is pushed out of a nozzle onto the paper. Piezo-electric: A crystal is located at the back of the ink reservoir of each nozzle. The crystal receives a tiny electric charge that causes it to vibrate. When the crystal vibrates inward, it forces a tiny amount of ink out of the nozzle. The bubble-jet technique is more common so boiling ink and nozzle is the correct answer.
