PostSubject: Inkjet printer    Thu 13 Jan 2011, 10:01 am

How does an Inkjet printer work actually depend upon the method employed to print the images. An Inkjet printer contains multiple nozzles that creates image by spraying tiny dots of ink on the paper. These tiny dots are precisely placed with perfect resolution of 1440 x 720 dots per inch (dpi). An Inkjet printer employs two methods for printing images on paper. The first method is thermal bubble method and second is piezoelectric method. In thermal bubble method resistors present in printer heat up to form multiple bubbles in the ink. These bubbles collapse and push the ink into cartridge that creates image on paper. While in piezoelectric method ink electric current is produced to vibrate the small crystals present in the nozzle. This vibration pushes the ink into cartridge to form the image on paper. Piezoelectric method produces smaller drops as compared to thermal bubble method to ensure producing the better quality image.
