The toner is used in photocopiers to form the latent electrical image on the drum. The paper picks up the toner particles (image), when it slides over the drum. Specific factors cause 10% of toner particles (approximately) to be left over the drum. This left out toner is cleaned by the unit to ensure the copy quality of the proceeding copies. This left out toner is called as waste toner and is collected in cleaner sump. If this waste toner is used in the photocopiers, the quality of the copier is reduced. The waste toner is mixed in proportion with Nano phase Carbon and original toner to get Hybrid Black Toner. The original toner is the toner prescribed for the photocopier by the manufacturer. By implementation of this technique, the cost of photocopy can be reduced and the quality of the photocopy can be increased. The Hybrid Black Toner is synthesis is optimized by Single Variable Optimization Algorithm.
