Abstract
There are provided a method for controlling the mode of a developing station of a liquid electrophotographic printer and a development roller driving apparatus therefor. In the controlling method, a printing mode, a drip line removal mode and a home mode are sequentially performed, and a development roller is subjected to racing in the home mode to be cleaned. Since the development roller is cleaned in the home mode in which the development roller is spaced apart from a photosensitive belt, the photosensitive belt is not contaminated by the development roller while cleaning the development roller. Also, the cleaning of the development roller is performed after completing a drip line removal mode, so sufficient cleaning time can be obtained. The development roller driving apparatus for implementing the controlling method includes a motor which is a driving power source, a reduction gear train for reducing and transmitting power of the motor, a power relay gear engaged with the reduction gear train, and a link/gear assembly for transmitting the power relayed by the power relay gear to the development roller gear. Accordingly, the development roller can be rotated in any position corresponding to the printing mode, the drip line removal mode or the home mode. Therefore, the cleaning of a development roller is allowed in the home mode.
