• a wipe unit which is mounted on the cap unit, and cleans the nozzle surface;
• a cover provided above the wipe unit;
• an engagement member which is provided so as to be movable upward and downward, and is engaged with the wipe unit to separate the wipe unit from the cap unit when it is moved upward higher than a predetermined height;
• a first cam which moves the engagement member upward and downward;
• a second cam which is interlocked with the first cam, and moves the cover upward and downward;
• a lifting device which lifts and lowers the head unit relative to a conveyance path along which a sheet is conveyed;
• and
• a sliding device which slides the cap unit to a maintenance position below the head unit relatively lifted by the lifting device and a home position on a lateral side of the maintenance position, wherein
• the first cam and the second cam are displaced into a first state, a second state and a third state,
• in the first state, the first cam moves the engagement member downward to the predetermined height or below and the second cam brings the cover into contact with the wipe unit,
• in the second state, the first cam moves the engagement member downward to the predetermined height or below and the second cam moves the cover upward to a height higher than the first state, and
• in the third state, the first cam moves the engagement member upward to the predetermined height or above and the second cam moves the cover upward to a height higher than the first state.
