During which step does the drum roller get charged back to its original state?

• A. Developing
• B. Fusing
• C. Cleaning
• D. Exposing

Answer: (C)

The correct answer is the last step of the printing process known as cleaning. During this phase, the drum roller, which has already been used in the printing cycle, is cleaned to remove any residual toner and prepare it for the next print job. This process also includes recharging the drum back to its original state, ensuring that it is properly ready to accept a new image. This is essential because if the drum were not recharged, it would not function correctly for subsequent prints, leading to poor print quality or misprints. In contrast, the developing step involves the transfer of toner to the drum, the fusing step is where the toner is melted and bonded to the paper, and the exposing step is where the laser or LED exposes the drum to create an image. These steps are crucial for the printing process but do not involve recharging the drum's surface to reset it for the next cycle.
