ABSTRACT:
A method of controlling the operation of a ribbon motor for a color printing system, including the stop of rotating a ribbon in reverse by one color pitch so as to prevent the deterioration of print quality due to dust particulates on a surface of the ribbon after the completion of the printing operation. The above method further includes the steps of counting the time that the printing system is in a standby mode after the printing operation; and presetting a critical point in the printing system in order to compare the time that the printing system is in the standby mode with the critical point.
