Abstract
An ink jet apparatus has discharge openings for discharging yellow, cyan, magenta and black inks. Suction recovery in the apparatus is performed using a cap which caps all of the discharge openings collectively. A suction opening is located in the cap closer to the discharge openings for dark (e.g. black) ink than to the discharge openings for light (e.g. yellow) ink. When suction is applied to the cap, ink is drawn from all the discharge openings, and mixing of inks close to discharge openings for light-color inks is minimized.
