Abstract
To allow accurate positioning relative to a printer mechanism, a printhead is provided with a reference surface formed on a reference member. The reference member is attached to the base of the printhead but positioned with reference to a nozzle of an ink ejecting unit mounted on the base member. This obviates the need for the base member to be manufactured to narrow tolerances.
