ABSTRACT:
A method of aligning individual printhead modules (2) in a pagewidth printer, the printhead modules (2) being mounted adjacent each other along an elongate support (3). Fiducial marks are formed on each of the printhead modules (2) for viewing through a microscope as the printhead modules (2) are positioned on the elongate support. The microscope has reference marks that can be brought into registration with the fiducial marks of adjacent printhead modules to align them. The reference marks are calibrated to incorporate an alignment error that is equal and opposite to the relative displacement of adjacent printhead modules from ambient temperature to the operating temperature.
