All of the above E. None of the above

The correct answer is: B. Transferring

In the laser printing process, a positive charge is placed on the paper to pull the toner from the print drum during the transferring phase.

The laser printing process consists of the following steps:

  1. Charging: The paper is given a negative charge.
  2. Writing: A laser beam is used to create an image on the photosensitive drum, which is positively charged. The areas that are exposed to the laser lose their charge, while the areas that are not exposed to the laser retain their charge.
  3. Developing: Toner, which is a negatively charged powder, is attracted to the positively charged areas of the drum.
  4. Transferring: The toner is transferred from the drum to the paper.
  5. Fusing: The toner is fused to the paper using heat and pressure.
  6. Cleaning: The drum is cleaned to remove any residual toner.

The transferring phase is when the toner is transferred from the drum to the paper. This is done by applying a positive charge to the paper. The toner, which is negatively charged, is attracted to the paper and is transferred to it.

The other options are incorrect because they do not describe the phase of the laser printing process in which a positive charge is placed on the paper to pull the toner from the print drum.

  • A. Writing: In the writing phase, a laser beam is used to create an image on the photosensitive drum. The areas that are exposed to the laser lose their charge, while the areas that are not exposed to the laser retain their charge.
  • C. Conditioning: In the conditioning phase, the paper is given a negative charge. This helps to ensure that the toner will be attracted to the paper during the transferring phase.
  • D. All of the above: This option is incorrect because it includes options that are not correct.
