ABSTRACT:
A method of forming a liquid jet recording head includes the steps of forming multiple resistive heaters and corresponding electrode pairs on a substrate, one of the electrodes in each pair being connected to a common test electrode formed on the substrate. After the head is tested to determine if there are any defects in a protective layer on the heaters and electrode pairs, the portion of the substrate carrying the test electrode is removed.
