I have read it back in my High School that some metals have photoelectric effect, i.e. a charge is generated on them when light falls on them. Selenium, Cadmium are some of the common elements that demonstrate photoelectric effect. Nowadays amorphous silicon being used as a photoconductor in the photocopying machines. When a reflection from the original falls on the photoconductor unit then there is a charge difference in the areas where the document is blank and where it is printed. This makes the photoconductor surface charged unevenly. At this time, the toner which is again a charged colloidal powder (charged opposite to the charge generated on the photoconductor) is applied on the surface and it sticks to the areas where the photoconductor is charged. Thus the image is formed on the photoconductor unit. In order to transfer this image to paper, a transfer charge is applied on the paper which again is of opposite nature than the charge of toner. Thus the charge generated on paper attracts the toner particles and thus the image is transferred to the paper. This paper then goes into the fuser section where the toner is melt by applying heat and pressure and thus fixed. The final product is a photocopy.

Will photostat machine puts its serial Number on photostat copies. If yes where it will put and it can be seen?
Not all but color copiers are recommended to put a unique identification mark on each copy they produce in order to trace the origin of machine in event of any counterfeiting. Many copier manufacturer companies in their catalogues write that this identification code is visible under a special light (such as UV or IR). However, even it is so, the old copier market which is growing so rapidly and where no records of sales are kept make it difficult for tracing down the machine even with the unique identification code. A better way to check the counterfeiting is exercising self discipline.
