Around 1938, the famous American physicist Chester Carlson requested a system that would allow him to copy paper documents although the first copier produced by the Xeox brand did not last until about a decade. It was only marketed but the system was patented. The reason such a major patent commercialization took so long is because of Carlson’s ability to get the industry interested in his invention.

Eventually a small family business Haloid Company, later Xerox bought the copier’s patent from Chester Carlson. Therefore the first copier was manufactured in 1947.

What is a copier?

It is a machine that can copy documents on a sheet of paper or on the most complicated paper, and it can be completed on other types of materials such as transparencies, and others.

  • Place the document to be copied on the glass screen (obviously very clean)
  • Light colored areas of the paper to be copied will destroy the positive charge on the board. In this way, an image of black areas on the paper can be created on the printing plate based on the positive charge (where the black ink has a positive charge remaining on the board).
  • Spray negatively charged powder on the board. The dust binds magnetically to the area where the positive charge remains.
  • Remove any dust that has not adhered to the board and that corresponds to the white area of ​​the paper.
  • Put a piece of paper on the board and transfer the powder (toner) to the paper by heating it.
  • Ready to go.

Parts of a copier

  • Glass surface: Where the paper to be copied is placed
  • Light source: Emits light from the photoreceptor and then receives it.
  • Drum: Receives light and energizes dark parts to attract toner
  • Toner: It is dry ink. Once attracted to the roller, it will be captured on the paper.
  • Fixing unit: Responsible for melting the toner on the paper.


Pioneers in this sector of machines:

  • Ricoh
  • Lexmark
  • Samsung
  • Brother

Types of copier

  • Xerographs
  • Electrostatic

Useful life

When you want to measure the life of a copier it is not measured by time but by the number of pages copied. The lifespan of small home copiers is about 15,000 copies, the lifespan of medium home copiers is about 60,000 to 100,000 copies, and the lifespan of large ones is 250,000 copies.
