The Long Life Technologies of Amorphous Silicon Drum in the TASKalfa 6052ci

Abstract

TASKalfa 6052ci which launched September 2016 has many new technologies, energy saving, high image quality and high reliability, also it achieved miniaturization with its machine size and weight decrease about 20% from previous model. Especially, we focused that the cause of wear of the cleaning blade edge depends on the shape changes of a-Si drum surface, and we tried to modification of the drum surface. As a result, the wear amount of the cleaning blade edge was reduced to about 25%, also, the cleaning performance for high circularity toner was improved, and it contributed to the low drive torque for the drum unit. In this article, we report the surface modification of a-Si drum that contributed greatly to the reliability of TASKalfa 6052ci.
