Abstract

A printhead assembly comprising leak-free damper elements with optimized compliance is provided by the steps of: - forming a plurality of damper cavities (52, 56, 57) in a support structure (3); - providing the support structure with a damper membrane at a first pressure for sealing off the damper cavities (52, 56, 57) from the ambient for maintaining the first pressure inside the damper cavities (52, 56, 57); - detecting a deformation of portions of the damper membrane over the substantially sealed damper cavities (52, 56, 57) at a second pressure different from the first pressure; and - equalizing pressures on opposite sides of the damper membrane.
