Abstract

Applying a hard coating on a printhead has the potential to increase head life. The method is as follows: 1. Apply a conductive polycarbonate film approximately 1 mm to the electrode assembly. 2. Remove the polycarbonate from the electrode tips by passing current pulses through the tips as the tips are moved across a conducting polycarbonate ribbon. 3. Deposit hard coating of titanium nitride. 4. Dissolve remaining polycarbonate with methylene chloride and lift off excess hard coating between electrodes, leaving only on electrode tips.
