RICOH Pro C900 is the first full-color printer for the production printing market for RICOH. In this market, it is very important to secure stable image quality and high reliability. This product newly introduced two technologies to achieve these key factors. The former is the new control algorithm to stabilize the image quality. A Charging bias, an exposure power and a development bias are controlled according to this algorithm. This brought the superior image stability in any image patterns. The latter is the design of the high durability and long lifetime. After several improvements and optimizations the lifetime of the developer was lengthened 6 times, the OPC was lengthened 3 ∼ 4 times and the photoconductor drum cleaning unit was lengthened 2 times compared with the conventional one.
