Patent ID: 7971876

Claim:
A system for aligning a modular printer assembly comprising: at least two driven transport modules for altering substrate media passing therethrough, each transport module including a transport belt for engaging and conveying the substrate media therethrough, each transport module including at least one edge sensor for detecting a position of the transport belt therein; at least one module alignment subsystem for aligning two adjacent ones of the at least two driven transport modules based on a relative skew indicated by a first position and a second position, the first position detected by the at least one edge sensor in one of the two adjacent transport modules and the second position detected by the at least one edge sensor in the other of the two adjacent transport modules; and an alignment substrate media for passing through the at least two transport modules, the alignment substrate media transferring the relative skew between the two adjacent transport modules to their respective transport belts for aligning the at least two driven transport modules.
