ANSWERS: 1
  • Toner is a powder used in laser printers and photocopiers to form printed text and images on the paper. A heat fusion process binds the toner particles to the paper.

    How does it work?

    The image or text to be printed is translated onto an electrically charged plate in the printer. The toner particles are attracted to the charged areas and transferred to the paper.

    What is it made of?

    Toner is made from carbon powder mixed with polymers, which aid the binding process. Exact formulations vary between manufacturers and printer brands.

    Colors

    Toner is available in black, cyan, yellow and magenta. The printer uses combinations of these colors to achieve the full color spectrum.

    Health risks

    Airborne toner particles can be irritating to the respiratory system, particularly for people with existing conditions such as bronchitis or asthma.

    Environmental issues

    Most toner cartridges are able to be refilled by third-party suppliers in order to reduce waste. The cartridges can be refurbished or recycled into new cartridges.
