Ever wonder what the major parts of a copier are? Here is a 10,000 foot view:
- The Document feeder correctly presents the paper to the Scanner
- The scanner collects the image digitally in most cases and passes it along to the imaging unit, comprised of a laser and a electrostatically charged roller called a drum
- The laser shines the image on the drum drum
- The drum loses its charge where the laser hits and the toner (a dry powder) sticks to these areas because it has the opposite charge
- The paper is fed under the drum, pressing the toner onto the paper
- Then the paper passes between two rollers, one of them, called the fuser, is heated and melts the toner into the paper.
- And the paper exits the copier onto a catch tray.

Piece of cake!
