An application unit includes an application material container to contain an application material, and an application needle to apply, to a target surface, the application material contained in the application material container. A first hole is formed in a bottom of the application material container, and a second hole is formed in an upper lid of the application material container. The application needle is configured to be movable along a line passing through the first hole and the second hole. A third hole is formed in a part of the application material container for allowing air to pass through the third hole, or a lowermost end of a wall of the first hole has a chamfer.

An integrated inkjet module includes: a chassis having an elongate base plate and a rear wall extending upwards therefrom; an elongate printhead liftably mounted on the chassis; a lift mechanism operatively connected to the printhead for lifting and lowering the printhead relative to the base plate; a capping assembly slidably mounted on the base plate, the capping assembly having a capper extending parallel with the rear wall and the printhead; a capper movement mechanism operatively connected to the capping assembly for linearly slidably moving the capping assembly towards and away from the rear wall; and a cap cover pivotally mounted to the rear wall. During use, engagement of part of the capping assembly with the cap cover pivots the cap cover away from the capper to allow sliding movement of the capper towards the rear wall and into a covered position.
