ABSTRACT:
A fabricating process for pagewidth reading and/or writing bars assembled from subunits, such as ink jet printhead subunits, is disclosed. At least two lengths of subunits are cut and placed on corresponding flat containers. An assembly robot places the subunits in a butted array on an alignment fixture and checks the accumulated positional error of the subunits as they are being assembled. When the robot detects an error exceeding some preset limits, it chooses a subunit of a known size to compensate for the detected error.
