摘要： PROBLEM TO BE SOLVED: To provide a highly reliable inkjet recorder capable of surely preventing waste ink from being deposited in a waste liquid tank and ink from adhering to a stirring member.
SOLUTION: This inkjet recorder comprises the stirring member for stirring deposited materials of waste ink stored in the waste liquid tank, the ink being ejected in the operation except the recording, and a washing means for washing the stirring member. As a result of the above structure, the waste ink deposited on a part can be diffused in the whole of the waste liquid tank, and then the waste liquid tank can be efficiently utilized. When ink adheres to the stirring member, a misoperation may occur. In the case where the stirring member has a rib, the rib is rounded by the waste ink so that the efficient stirring can not be carried out. By providing the function of washing the stirring member, adhering of the ink to the stirring member can be prevented, reliability of the stirring function can be enhanced, and the efficient stirring can be carried out.

摘要： PROBLEM TO BE SOLVED: To eliminate tube clogging, and to prevent machine-down caused by the tube clogging even at the occurrence of the tube clogging caused by ink sticking.
SOLUTION: A suction pump is driven to perform first ink suction from a recording head (S101). When failing in suction, whether an apparatus has been left for a long time is checked (S103), and unless it has been left for a long time, a user is informed of the machine-down (S111). If it has been left for a long time, whether there is a negative pressure change indicating the suction of ink is checked (S104). Unless there is the negative pressure change, a machine is stopped, and the user is informed of the machine-down (S111). If there is the negative pressure change, the suction pump is driven at maximum pressure to perform second ink suction (S105-S108). If suction is successful after the second suction (S109), return is performed as it is, and if suction is a failure, the user is informed of the machine-down (S110).
