👉 Fax fluid, also known as xerographic toner or powder, is a dry, fine powder utilized in fax machines to transfer images from a document to a recipient's printer. This powder is electrostatically charged and selectively attracted to the positively charged drum inside the fax machine, forming an image of the scanned document. Once the image is created, it is fused onto a piece of paper using heat and pressure, effectively creating a physical copy of the original document. This process allows for rapid, high-quality image transmission without the need for physical contact or traditional ink-based methods.
