Method of making compensated collinear reading or writing bar arrays assembled from subunits

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