Printer speeds can be slower. Each nozzle contains a heater. When the heater is charged, a bubble forms, forcing ink out of the nozzle. An ink reservoir replenishes the ink in each of the nozzles that were fired. Laser A laser beam is focused on a photoelectric belt or drum, creating an electrical charge.
Electrostatic charges cause the toners to adhere to the belt.
The image is then transferred to a drum which rolls the toners onto the sheet of paper, toners are then heat-fused using heat alone or in combination with pressure. Fast and do not require special papers, reducing printer supply costs. Quality is not as high as dye sub printers. Solid Ink Color sticks of a crayon-like ink are installed in the printer. As the color sticks melt, the image is made when the liquefied ink is sprayed through tiny nozzles onto the paper's surface.
