The type of printer that uses a rotating photosensitive print drum is the laser printer. In this technology, a laser beam selectively charges the drum to create an image, which is then transferred onto paper using toner. The drum rotates to facilitate the printing process, allowing for high-speed and high-quality prints.

What is a Photosensitive drum?
Aluminum cylinder coated with particles of photosensitive compounds. Used in a laser printer and often contained within the toner cartridge.

What is the purpose of cartridges used within laser printers?
The cartridges in laser printers contain toner that allows the print to show on the page. A laser printer works by having a laser directed at a photosensitive drum. Without the toner, charged particles from the drum would be transferred to the paper, but they would be colorless.
What can damaged the photosensitive drum on a laser printer?
Some of the things that can damaged the drum on the laser printer are and should be avoid. Do not expose the drum to the light for more than few minutes, the drum should never be touched, also keep away from dust and dirt, as well as humidity and high-temperature areas.
Why called laser printers?
The HP Laser Printer is a printer produced by HP. It uses laser technology to work more efficiently than the previous prototypes. Because of this new technology, the printer is best used to mass-produce papers. There are also subdivisions of the HP Laser Printers, which are: HP Laser Jet 4000, HP Laser Jet 4050, and HP Laser Jet 4250.
What is primary corona wire?
It's a component in a laser printer that Fuses the toner to the paper.
What is a photoreceptor drum?
A photoreceptor drum is a component of a photocopier or printer that contains a photosensitive material. This material is charged by a laser or LED, and the image to be printed is projected onto it to create an electrostatic charge pattern. The toner particles are then attracted to and transferred from the drum onto the paper to create a physical copy of the image.
What happens during the writing stage of laser printer operation?
After rotating past the conditioning station, the drum has a uniform high negative charge on its surface. At the writing station, a sweeping laser beam is used to discharge this potential in selected areas by focusing laser light on selected portions of the photosensitive drum. This creates what is known as an electrostatic image. This image is later developed into a visible image. Portions of the drum not exposed to the laser still have a high negative charge. In short the laser writes the image on the drum.
Functions of laser printer?
The first step in creating a laser printout, is for the printer to remove any toner from the drum from a previous print. The printer than conditions the drum by removing any latent images. A new image is then inscribed onto the drum using the laser to charge parts of the drum. Toner is applied to the drum, and the image is transferred to paper. Finally the toner is fused to the paper through heat and pressure.
How can staticelectrisity be used in printers?
A laser printer uses a laser-beam that projects an image of the page to be printed onto an electrically charged rotating drum.
What kind of printer uses static electricity to produce an image on paper?
A laser printer uses static electricity to produce an image on paper. The process involves a laser beam to form an electrostatic image on a photosensitive drum, which attracts toner particles to transfer and fuse onto the paper.
What printer use a drum and toner in the printing process?
A Laser printer uses a drum and toner. A laser negatively charges the drum (a big rotating tube) at certain points, making a mirror copy of the item to be printed. The drum rotates past a toner cartridge, in which are positively charged particles of toner. The positively charged toner is attracted to the negatively charged parts of the drum, and leaves the neutral space in between blank. The drum then presses onto a sheet of paper, transferring the image. A quick heat of the paper seals in the toner (That's why the paper is always warm when it comes out of the printer), and there you go, an image!
