Abstract
When one of first to third power supply circuits breaks down, a change-over switch performs switching of electrical connection such that drive voltage is allowed to be supplied from normal one of the first to third power supply circuits also to one of the inkjet heads connected to the breakdown power supply circuit. Consequently, the power supply circuits are partially sharable with a plurality of inkjet heads, causing no necessity of stopping the apparatus for replacing one breakdown power supply circuit. As a result, suppression in decrease of throughput of the apparatus is obtainable.
