Patent abstract
A capping unit for use with a liquid discharge head. The capping unit includes a cap for covering a discharge surface of the liquid discharge head. The cap includes air-communication openings provided at corners of the cap, and a suction opening. The air-communication openings connect a space in the cap with the atmosphere. A high negative pressure pump provides pressure to the space via the suction opening. The cap minimizes liquid spatter on the discharge surface after a suction process.
