Abstract
An inkjet printing apparatus and a print head recovery method are provided according to which, in an environment in which dust (e.g., paper dust) is easily attached to the periphery of an ejection port of a print head, the print head is subjected to a recovery operation depending on the level of the attached dust. The inkjet printing apparatus has a cutter unit for cutting a print medium and a recovery unit for performing the recovery operation by wiping the ejection port formation portion at which the ejection port is formed of the print head while sucking the ejection port formation portion. When the passing number showing how many times the cut part of the print medium cut by the cutter passes the printing position is equal to or higher than a threshold value, the recovery means subjects the print head to the recovery operation.
