Correct Response: C. A laser printer contains a positively charged drum. The laser shines on specific spots on the drum, causing them to become negatively charged. Fine, positively charged toner particles stick to the spots on the drum that were negatively charged by the laser. This creates the image that is transferred to the paper through the action of the hot fuser. The laser is not involved in the fusing of the toner particles (A). There is no original printed document (B) since this is a printer, and not a scanner or a copier. The laser is not used to heat the paper (D).
