The correct answer is: A laser printer does NOT use a photo-conductive drum.<\/p>\n
A laser printer is a type of computer printer that uses a laser to produce images on paper. The laser beam is used to create an electrostatic charge on a photosensitive drum. The drum is then coated with toner, which is attracted to the charged areas. The toner is then transferred to paper and fused to the paper using heat and pressure.<\/p>\n
A photo-conductive drum is a cylindrical drum that is coated with a photoconductive material. The photoconductive material is a material that changes its electrical resistance when exposed to light. When the laser beam strikes the photoconductive drum, it creates an electrostatic charge on the drum. The charge on the drum attracts toner, which is a powder that contains ink. The toner is then transferred to paper and fused to the paper using heat and pressure.<\/p>\n
A print head is a device that contains the print cartridges. The print cartridges contain the ink that is used to print the image. The print head moves across the paper and sprays the ink onto the paper.<\/p>\n
A laser beam is a beam of light that is produced by a laser. The laser beam is used to create an electrostatic charge on the photoconductive drum.<\/p>\n
Therefore, the correct answer is: A laser printer does NOT use a photo-conductive drum.<\/p>\n","protected":false},"excerpt":{"rendered":"
