Abstract

An ink-jet print head circuit, which is set in an ink-jet print head of a printing apparatus, is provided. The ink-jet print head circuit comprises at least a test pad that couples to a circuit of the ink-jet print head, and the test pad is used only for measuring the signal characteristic of the circuit of the ink-jet print head but not for signal transmitting between the ink-jet print head and the printing apparatus.
