Detailed explanation-1: -In a laser printer, what must be done to the drum to make it receptive to new images? It must be charged with a uniform negative charge.
Detailed explanation-2: -The basic components of a laser printer Initially, the drum is given a total positive charge by the charge corona wire, a wire with an electrical current running through it. (Some printers use a charged roller instead of a corona wire, but the principle is the same.)
