The present invention provides for a method of aligning two or more printhead modules mounted to a support member in a printer. The printhead modules are MEMS manufactured integrated circuits having at least one fiducial on each. The method includes the steps of positioning the printhead modules on the support member such that they align when the support member is at its operating temperature but not necessarily at other temperatures, and using the fiducials to misalign the printhead modules by a distance calculated from the difference between the coefficient of thermal expansion of the support member and the printhead integrated circuits, the spacing of the printhead chips along the support member and the difference between a production temperature of the modules and an operating temperature of the printer.
