Abstract
A maintenance jig includes a protector and an opening. The protector is configured to be attached to a head that has a nozzle surface including a nozzle row to discharge liquid or a head holder that holds the head. The protector is configured to protect the nozzle row. The opening is adjacent to the protector in a lateral direction of the nozzle row intersecting a longitudinal direction of the nozzle row. A distance between an end of the protector in the longitudinal direction of the nozzle row and the nozzle surface is larger than a distance between a portion of the protector other than the end of the protector in the longitudinal direction and the nozzle surface when the maintenance jig is attached to the head or the head holder.
