Laser Printers

Printing has been a part of mans breeding even since the Stone Age, whether it was writing on walls, tablets of stone, hieroglyphics, to a typewriter, or the feeling press. In the past thirty years, technology has allowed mental picture to be taken to a whole other level. This raw level is known as Laser Printing. Its process has make printing more efficient and cost effective for the smell of print.
There are six footsteps to the optical maser printing process, the first of which start with cleaning. Before the paper enters the printer, the drum, where the next film is to be stored in the beginning being put on the paper, must(prenominal) remove any pleonastic toner from the surface of the drum by using either a blade or an AC emf on a wire to discard the excess toner into a used toner container for later cleaning or discarding. The arcsecond step is called conditioning which involves the charging of the drum with a high voltage wire to give it a ban charge. Directly after this happens, the third step, writing, takes place. This is where a laser is shines down on the sensitive drum to lower the negative charge of where the image allow appear on the drum. In the fourth step, known as the developing phase, the toner is applied to the invisible image on the drum. The comptroller blade holds the toner at a microscopic distance from the drum.



The toner is consequently transferred to the more positively charged part of the drum where the laser exposed light. Since the drum was charge with a strong negative charge, the paper the image will be placed on must have a positive charge, to attract the toner to it. This step is known as the transfer stage. The transfer roller places a strong positive charge on the paper before moving it further past the drum where the toner will be transferred to the paper. But the toner is not completely attached to the paper yet. The farthest stage is called the fusing. This is where the paper moves through the heated roller and the compel roller, the loose toner is melted and fused...If you want to get a abounding essay, order it on our website: Orderessay
