Detailed explanation-1: -Exposure. A laser is used to write the image onto the charged surface (see Figure 6.6). Because the photosensitive coating on the drum becomes conductive when exposed to light, the charges on the surface of the drum exposed to the laser conduct to the base layer, which is connected to a ground.
Detailed explanation-2: -During the laser printer process, after the erase lamp exposes the entire surface of the photosensitive drum to light, what happens to the photosensitive coating? It becomes conductive. What does the primary corona wire charge? The toner in a laser printer is a fine powder.
Detailed explanation-3: -The transfer belt rolls the paper through the printer giving it a positive charge. As it passes the drum, the negatively charged toner is attracted to the page in the shape of your print. The toner is then melted to the paper by hot rollers called the fuser unit, and voila, your page is printed.
