How does a photocopier work?
The drum is selectively charged with static electricity to mirror the image that is being copied. The toner, which is black powder, then adheres to the charged areas of the drum.
What is a photocopier toner used for?
Toner is a negatively charged plastic based fine powder that helps create the image on the copy. For the drum and the copying paper to have a positive charge, the copier needs corona wires. The wires are exposed to high energy, which they transfer to the drum and paper in the form of static electricity.
What is the last step in photocopying?
The fuser is the last step of the photocopying process and is what makes the image permanent on the page. The fuser unit is made up of two Teflon covered rollers which have quartz tube lamps inside of them that generate heat.
What is a drum in photocopying?
The drum is a metal roller that is layered with photo conductive material made from a semi-conductor such as silicon, germanium, or selenium. In the dark these materials act as insulators, however, when hit by light they become conductors and allow currents to pass through them. The drum is positively charged and has a big impact on the photocopying process.
