A method for processing a thin film layer, for example to form an ink jet printhead, can include the use of an adhesive layer that can be converted from a first state having a first adhesive force to a second state having a second adhesive force, where the first state is stronger than the second state. Conversion from the first state to the second state can be performed using a suitable treatment. In an embodiment, the adhesive layer may be a thermal release material that is converted during a heat treatment. In another embodiment, the adhesive layer may be a layer that is sensitive to ultraviolet (UV) light, and is converted during exposure to UV light emitted by a UV light source.

A three-dimensional object printer compensates for variations in ejected material drop volumes by adjusting firing signal parameters. The printer includes an optical sensor that generates height measurement data of columns of material in a test pattern. Differences between the height of columns of material in the test pattern formed by the ejectors in the printhead and the expected height of the columns are compared to a predetermined range to detect drop variations that are out of tolerance. The modification of the firing signal parameter adjust the operation of the ejectors to bring the volume of the drops ejected by the ejector within tolerance range to reduce the ink drop velocities of the ejected drops within a predetermined range.

A printhead enables surface treatment fluid to be applied to the face of the printhead through at least one aperture located in the printhead faceplate. The printhead receives pressurized surface treatment fluid, which flows through a reservoir in the printhead, through at least one channel in the jet stack, and out the at least one aperture onto the surface of the faceplate. The surface treatment fluid is spread across ink apertures in the faceplate to disable ink from drooling from the ink apertures.
