Abstract: A belt drive module and a corresponding method includes or employs a belt that moves along a path, at least one support roller or other structure that supports the belt as it moves along the path, a drive roller that effects movement of the belt along the path, a tension roller that applies a tension force to the belt in order to maintain engagement of the belt with the drive and/or support rollers, at least one processing station (e.g., an image processing station) disposed along the path that performs a process relative to a predetermined position of the bel t, and a torque assist drive that applies a torque assist force T d at a location between the drive roller and the tension roller. Torque assist may be provided by a current limited DC motor or by a constant torque friction clutch applied to a roller , e.g., a stripper roller of an electrophotographic imaging system. Advantageously, th e torque assist force T d facilitates accurate positioning of the belt (e.g., latent image registrations in a color imaging process employing multiple imaging processi ng stations) by reducing slippage between the drive roller and the belt that ma y be encountered due to belt wear, toner contamination and/or other debris.

Abstract: A belt drive module and a corresponding method includes or employs a belt (10) that moves along a path, at least one support roller (12) or other structure that supports the belt as it moves along the path, a drive roller (11) that effects movement of the belt along the path, a tension roller (74) that applies a tension force to the belt in order to maintain engagement of the belt with the drive and/or support rollers, at least one processing station (e.g., an image processing station) disposed along the path that performs a process relative to a predetermined position of the belt, and a torque assist drive that applies a torque assist force (Td) at a location between the drive roller and the tension roller. Torque assist may be provided by a current limited DC motor or by a constant torque friction clutch applied to a roller (66), e.g., a stripper roller of an electrophotographic imaging system. Advantageously, the torque assist force (Td) facilitates accurate positioning of the belt (e.g., latent image registrations in a color imaging process employing multiple imaging processing stations) by reducing slippage between the drive roller and the belt that may be encountered due to belt wear, toner contamination and/or other debris.

Abstract: PROBLEM TO BE SOLVED: To restrain the slip of a belt at the time of driving the belt. SOLUTION: A belt driving module and a corresponding method include or adopt the belt moving along a path, at least one supporting roller or another structural body to support the belt when the belt is moved along the path, a driving roller to move the belt along the path, a tension roller to apply tensile force to the belt in order to maintain the coupling of the belt with the driving roller and/or the supporting roller, at least one processing station (for example, image processing station) arranged along the path in order to perform a process related to the specified position of the belt, and a torque supporting and driving part to apply torque supporting force Td at a position between the driving roller and the tension roller. The torque supporting force Td makes the exact positioning of the belt easy by reducing the slip between the driving roller and the belt.
