A nip mechanism for a substrate transfer system allows the nip mechanism to be actuated such as opened and/or closed by the drive motor for the nip mechanism. As a result, the need to operate the nip mechanism pneumatically, for example, can be avoided. Essentially, the drive motor now performs a dual role, i.e., both driving the nip rollers and also opening and closing the nip mechanism. The nip mechanism comprises a roller separation mechanism and a one-way clutch for engaging the roller separation mechanism when the drive motor is driven in the second direction. In the present implementation, this roller separation mechanism comprises a cam that pushes the first nip roller and the second nip roller away from each other. A cam limiter can be used to prevent over-rotation of this cam.
