Abstract Fuji Xerox is a joint venture partnership between the Japanese based company (photographic company) Fuji which holds around 75% of the share and Xerox which is an American documentation company Xerox holding a share of 25% in the Asia Pacific region and in Australia. The main products of the company is printers and copiers machine which can be used for office purposes to production purposes and the speed ranging from 10 to 120 colour A4 copies of pages a minute. Xerography which is called as the photocopying technique was invented by Chester Carlson in the year 1938 and obtained US patent in 1942. Carlson established the basic principles of xerography, although a great deal of research and development was required in order to…show more content…
DocuColor 1450 GA produce the accurate colour reproduction and high precision image quality which is needed for professional graphics. The printer comes with a server which gives higher image quality to the copies although the speed of the printer is limited to 14 A4 colour and 50 A4 black and white copies a minute. It uses 4-cycle Print Engine which is newly developed to attain superb image quality where each CMYK toner layer is transferred onto the same position on a media at once. This feature enables to prevent colour mis-registration or colour variation on a print. Condition on the drum surface directly impacts image quality. As there is only one drum, it is easier to control drum surface condition and to control image quality, comparing with a system with 4 drums. The drum used in this product is coated with 4 surfaces mainly grounding layer, charge production layer, charge transportation layer and protective layer. The protective layer prevents from scratches on the surface, contributing to generate high quality images consistently over the long…show more content…
By raster-scanning and exposing the Drum, the ROS forms an electrostatic latent image there. (4) The Developer Rotor is equipped with the four black, yellow, magenta and cyan Developer Housings (there is space for adding ones of two colours), which are supplied with toners from their respective Toner Cartridge Housings. When the Developer Housing of a specific colour to use is set at the development point, the electrostatic latent image on the Drum surface is developed with the toner. (4-cycle system). (5) The toner image developed on the Drum surface is transferred onto the IBT (Image Belt Transfer) by the 1st BTR (First Bias Transfer Roll). This is performed for each colour. Therefore, the IBT is rotated for the transfer of the toner images of a specific number of colours as many times as the number. (First Transfer) The IBT is a belt. The length of one cycle of the belt is exactly equal to that of two cycles of the Drum. In order for the toner images of the respective colours to be laid one on another at the same position for transfer, the TR0 Sensor detects the transfer reference position on the IBT. This transfer reference position is critical in controlling the copy
