摘要： An inkjet printing apparatus is provided which minimizes the amount of inks consumed for preventing the sedimentation of ejected inks on the platen ink absorber and which can effectively prevent the sedimentation of inks. To this end, a comparison is made between the ejected volume of easily sedimenting inks and the ejected volume of sedimentation restraining inks in terms of ink components. If the ejected volume of the sedimentation restraining inks is found not enough, a required amount of sedimentation restraining ink is additionally ejected.

摘要： Provided are an inkjet printing apparatus and a method of controlling an inkjet printing apparatus whereby the performing of a suction discharge operation, for air bubbles that have penetrated inside an ink supply line, can be suppressed to a minimum necessary number of times, and whereby the ink discharge volume that accompanies air bubble suction discharge operations can be kept low. The volume of an air bubble that penetrates into an ink supply line is estimated on the basis of an elapsed time since the last air bubble suction discharge operation, and in addition, the volume of an air bubble that penetrates into the ink supply line during main tank installation is predicted. The suction discharge operation (choke suction operation) for suctioning out and discharging air bubbles is conducted when the sum of these estimated volumes becomes equal to or greater than a predetermined value.

摘要： The inkjet printer can discharge a bubble in an ink flow path while suppressing ink consumption. Ink in an ink tank is supplied to a printing head through a flow path and filter. Bubbles in the flow path and printing head are discharged by applying a negative pressure to an ejection port of the printing head. At this time, after a first negative pressure has been applied to the ejection port with an on/off valve provided between the ink tank and the filter being closed, the on/off valve is opened to discharge the ink from the ejection port. Further, after that, a second negative pressure at a level that makes it difficult for a bubble to pass through the filter is applied to the ejection port to discharge a bubble present at a location, which is closer to the printing head than the filter is to printing head, from the ejection port together with the ink.

摘要： The inkjet printer in the present invention can discharge a bubble in an ink flow path while suppressing ink consumption. Ink in an ink tank is supplied to a printing head through a flow path and filter 48. Bubbles in the flow path and printing head 22 are discharged by applying a negative pressure to an ejection port of the printing head. At this time, after a first negative pressure has been applied to the ejection port with an on/off valve provided between the ink tank and the filter being closed, the on/off valve is opened to discharge the ink from the ejection port. Further, after that, a second negative pressure that prevents a bubble from passing through the filter is applied to the ejection port to discharge a bubble present more closely on the printing head side than the filter from the ejection port together with the ink.
