A media transport includes first, second and third media transports to convey a substrate media. A force transducer outputs a force signal associated with a force between the first and second media transports. A sensor outputs a detection signal associated with substrate media being between the second and third media transports. A control unit outputs a first control signal to the first and/or second drive units, dependent upon a comparison of the force signal with a predetermined value. The first control signal commands the first or second drive unit to drive respective first or second media transports to maintain the force signal at or about no greater than the predetermined value. Responsive to the detection signal, the control unit outputs a second control signal in place of the first control signal, commanding the first and/or second drive unit at a predetermined speed. |
