<p>An ink jet printer having a mechanism (4) to restore the nozzles (121-126) by suction, thereby preventing the contamination of the nozzles (121-126) of a printing head (11) caused by waste ink and the mixing of color of ink. The ink jet printer is provided with an air releasing unit (44) used to release a cap chamber equipped below the printing head (11) by a cap (421) of a capping unit (42). While ink droplets are discharged from the nozzles (121-126) of the printing head (11), nozzle suction is performed and the cap chamber is released to the atmosphere through the use of the air releasing unit (44). <IMAGE></p> |
