A connection inspecting method is provided to inspect the electrical connection between bumps and lands of a printer provided with an ink-jet head, FPC having the lands electrically connected to the bumps formed for the ink-jet head, and a driver IC. The connection inspecting method includes supplying a connection inspecting signal from the driver IC to the ink-jet head; detecting whether or not the ink liquid droplets are discharged from a certain nozzle; and judging whether or not the connection between the bump and the land corresponding to the certain nozzle is the normal connection. The connection inspecting signal is set so that ink liquid droplets are discharged from nozzles only when the connection between the bumps and the lands is the normal connection. |
