ABSTRACT:
A method of recovery of the ink ejection capability of an ink jet printhead having a deteriorated discharge condition by changing a relative contact pressure between the cleaning member and the printhead. A first wiping is carried out using the cleaning member such that an ordinary load for cleaning is applied at 50-200 grams/line of discharge openings of the printhead. A second first wiping is carried out using the cleaning member such that an ordinary load for cleaning is applied at 200-500 grams/line of discharge openings of the printhead when initiated by an operator of the ink jet printing apparatus.
