Toner using plant-derived plastic also exists as an alternative to petroleum plastic. [2] Toner particles are melted by the heat of the fuser, and are thus bonded to the paper. In earlier photocopiers, this low-cost carbon toner was poured by the user from a bottle into a reservoir in the machine [citation needed].
Xerography is a dry photocopying technique. [1] Originally called electrophotography, it was renamed xerography—from the Greek roots ξηρός xeros, meaning "dry" and -γραφία-graphia, meaning "writing"—to emphasize that unlike reproduction techniques then in use such as cyanotype, the process of xerography used no liquid chemicals.
The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet , but xerography is standard for office copying. Commercial xerographic office photocopying [ 1 ] gradually replaced copies made by verifax , photostat , carbon paper , mimeograph machines , and other ...

This is the formula that was used for the old Financial Times stock market index (the predecessor of the FTSE 100 Index). It was inadequate for that purpose. It was inadequate for that purpose. In particular, if the price of any of the constituents were to fall to zero, the whole index would fall to zero.
Its purchase price was $27,500, [11] which was established by the US Government, as they would not rent equipment. The customer also bought paper and toner (ink) at a cost of about 5 cents per copy. The customer also bought paper and toner (ink) at a cost of about 5 cents per copy.
The paper used in this process was coated with a zinc oxide powder, adhered with a resin, to make it able to hold an electrostatic charge, and absorb toner, to form an image and allow the evaporation of toner dispersants. Users of electrofax machines purchased paper with the coating already applied.
For the most part, toner systems are more economical than inkjet in the long run, even though inkjets are less expensive in the initial purchase price. Professional digital printing (using toner ) primarily uses an electrical charge to transfer toner or liquid ink to the substrate onto which it is printed.
