Abstract: An inkjet head maintenance device includes a base, a liquid supplier and a liquid collector. The base has an upper face disposed closely opposite a nozzle face of an inkjet head to form a liquid reservoir space during maintenance of the inkjet head. The base includes a liquid supply hole and a liquid collection hole that open to the upper face. The liquid supplier is configured to supply liquid from the liquid supply hole to the liquid reservoir space. The liquid collector is configured to collect the liquid in the liquid reservoir space from the liquid collection hole.
