What are the total number of steps in the electrophotographic printing process?

The electrophotographic printing process, commonly used in laser printers, consists of a series of detailed steps that enable the transfer of an image onto paper. The total number of steps in this process is seven, making the correct choice accurate.

To provide context for this, the seven steps include:

1. Charging: The photosensitive drum is charged uniformly by a corona wire or a charge roller.

2. Exposure: A laser beam is directed onto the drum, discharging specific areas to create an electrostatic latent image.

3. Developing: The toner, which is a fine powder with a charge opposite to that of the latent image, is applied and adheres to the charged areas of the drum.

4. Transfer: The toner image is transferred from the drum to the paper using another charged roller that pulls the toner onto the paper.

5. Fusing: The toner is permanently fused to the paper using heat and pressure, ensuring that the image is durable.

6. Cleaning: Any residual toner on the drum is removed so that the drum can be reused for the next print job.

7. Recharging: The drum is prepared for the next cycle by recharging it once
