Abstract:
1. A method of aligning transport modules in a printing system, the method comprising: passing at least one substrate media in a process direction through adjacent first and second transport modules, each of the first and second transport modules including a transport belt for engaging and conveying the at least one substrate media, at least one of the first and second transport modules having a transport belt steering control disabled; detecting a first position of a first edge of the transport belt in the first transport module, the first position representing a cross-process position of the first edge measured by at least one first edge sensor; detecting a second position of a second edge of the transport belt in the second transport module, the second position representing a cross-process position of the second edge measured by at least one second edge sensor; and aligning the first and second transport modules based on a relative skew indicated by the first position and the second position.
