Abstract

In a print head which can be mounted in a printer and which has a first ejection portion to eject an ink and a second ejection portion to eject a print performance improving liquid to aggregate or make insoluble the ejected ink, the storage method effectively prevents the mixing of the ink and the print performance improving liquid if one or both of these liquids should leak before the print head is mounted in the printer. The seal member having an opening and adapted to seal the first and second ejection portions so that its opening is located between these ejection portions is removably bonded to the print head. This arrangement closes the ejection portions with the protective tape, preventing leakage of the ink and the print performance improving liquid. If one or both of these liquids should leak, the liquid seeping toward the other ejection portion by capillary action generated at the joint portion between the protective tape and the orifice plate surface can be blocked by the opening of the protective tape that nullifies the capillary action.
