When is the stage called "Writing" in laser printing process?

In the laser printing process, the "Writing" stage specifically refers to the moment when the laser beam creates an image on the surface of the photosensitive drum. This occurs after the drum has been charged and develops a specific electrostatic pattern that corresponds to the intended printed text or image. The laser selectively discharges parts of the drum, allowing toner (which is attracted only to these discharged areas) to later adhere to the drum during the next phase of the process.

This stage is critical because it defines the quality and accuracy of the printed output; the precision with which the laser writes the image directly influences how well the final print will reflect the desired design or text. Other stages of the laser printing process involve cleaning the drum, feeding paper, and melting the toner, which do not directly involve the creation of the image itself.
