Thus, in the case where the print head moves, the ink discharged from the discharge port array in front of the moving direction tends to rise more as mist, thereby resulting in an increase in the amount of mist attached to the vicinity of the discharge port array.

Embodiment Construction
[0037] figure 1 is a front view showing an inkjet printing apparatus according to an embodiment of the present invention. Reference numeral 2 denotes a printing apparatus body including a conveying unit. This printing device prints images (including text and graphics) on relatively large print media. Reference numeral 1 denotes a carriage. The carriage 1 moves in a state where a printing head 5 provided with a plurality of discharge portions (discharge port arrays or nozzle arrays) for discharging ink is mounted. Reference numeral 33 denotes a guide shaft that guides the carriage 1 . The carriage 1 receives a driving force via a belt 34 to be reciprocally movable along a guide shaft 33 . Thus, the print head 5 is movable relative to the print medium. The print head 5 discharges ink while the carriage 1 reciprocates (ie, moves in a leaving direction and a returning direction) to print an image on a printing medium. In this embodiment, a total of four color inks of cyan (C...

An ink jet printing apparatus according to the present invention includes a print head, a carriage, a recovery unit and a controller. The controller causes the recovery operation to be performed based on the sum of the two values. On the assumption that the front array and the rear array of the discharge port array are defined as the first array and the second array, respectively, during the movement of the carriage in the departure direction, the first value is obtained by changing the distance from the first array during the movement of the carriage in the departure direction. The sum of the amount of ink discharged and the amount of ink discharged from the second array during movement in the return direction of the carriage is obtained by multiplying the first coefficient, and the second value is obtained by multiplying the amount of ink discharged from the second array during The sum of the amount of ink discharged and the amount of ink discharged from the first array during movement of the carriage in the return direction is obtained by multiplying the second coefficient.
Description
technical field [0001] The present invention relates to an inkjet printing device. Background technique [0002] Japanese Patent Application Laid-Open No. 2006-240174 discloses a technique of counting the number of ink discharges from the discharge port of the print head, and removing ink adhering to the discharge port surface of the print head using a wiping member using the discharge value obtained from the count. for recovery. According to this technique, the discharge port surface of the print head can be effectively cleaned. [0003] However, it is apparent that with the technique disclosed in Japanese Patent Application Laid-Open No. 2006-240174, the discharge port surface of the print head cannot be sufficiently cleaned in some cases. Specifically, especially in a serial type inkjet apparatus, an upward vortex (vortex flow) is caused by an air flow (spontaneous air flow) accompanying the ejection of ink droplets and an air flow (inflow air flow) accompanying the mov...
