Maalijauhe

Maalijauhe, also known as toner powder, is a fine powder used in laser printers and photocopiers to produce images on paper. It consists of finely ground plastic particles, pigments, and other additives. The powder is electrostatically charged and attracted to areas of an oppositely charged latent image on a photosensitive drum.

When paper passes over the drum, the toner powder is transferred from the drum to the paper. A fuser unit then heats and presses the toner, melting the plastic particles and fusing them permanently to the paper fibers. The specific composition of maalijauhe varies between manufacturers and printer models, influencing print quality, color reproduction, and durability.

Maalijauhe is typically stored in a toner cartridge, which is a replaceable component within the printer. These cartridges need to be replaced when the toner runs out. While generally safe for intended use, it is advisable to handle maalijauhe with care to avoid inhalation, as the fine particles can be irritating. Disposal of used toner cartridges should follow local environmental guidelines.
