摘要: A belt-tracking apparatus for a printing device has a steering roller, a guiding roller and a continous belt encompassing them. A belt-steering mechanism is arranged to counteract a lateral belt movement by adjusting the distance between one end of the steering roller and. the corresponding end of the guiding roller by means of an actuator. The actuator is movably mounted on a base structure and arranged to rotate a threaded control rod having two differentially pitched threaded sections. The first and second sections cooperate with corresponding threads of a base structure and of said end of the steering roller, respectively, so that a rotation of the control rod shifts said end of the steering roller relative to the corresponding end of the guiding roller, and the actuator relative to the base structure.
