#DOT MATRIX IMPACT PRINTER SERIES#

The pin then smacks the ribbon and then paper which leaves an imprint on the paper. When the solenoid receives that current, it fires the pin out of the print head.

To print, the printer sends electrical current through the pattern of those pins. In the back they also have an electrical solenoid. 24-pins create a near-letter quality print and anything with less than 24-pins provides a draft quality print.В Each of these pins is actually retracted inside the print head and theyвЂ™ve got springs that keeps them pulled inside of the print head. The most common number of pins on a dot matrix printer is 9, 18, or 24, with more pins providing a higher resolution.

Higher quality dot matrix printer might have upwards of 24 different pins. Inexpensive dot matrix printer will only have nine pins, as in our case. The number of pins in print head can vary. The tractor feed pulls a piece of paper and rolls it around the platen. The ribbon contains the ink that will be transfered onto the paper, and the tractor feed is used to draw continuous-feed paper up through the printer. Other components are ribbon and the tractor feed. ItвЂ™s like a big cylinder and its job is to hold the paper in place and serve as a backing to which the print head can hit. Platen is the black roller that we put paper through and roll it around. The second important component is called the platen.

The first is the print head which is a square block, and itвЂ™s got a series of pins. Key terms:В ink, paper, print, dot, matrix, jet, head, solid, laser, pins, dye, quality, ribbon, usb, parallelДЄ dot matrix printer is an impact printer that transfers characters by striking a pattern (from a matrix) through an inked ribbon and onto paper.В There are four critical components in a dot matrix printer. Objectives:В learn how do dot matrix, ink jet, solid ink, dye sublimation and laser printers work, and which type of interface can they use.
