Ink-jet cartridge and method of storing print head
First Claim
1. An ink-jet cartridge, comprising:
- a print head portion having a first ejection portion to eject print ink and a second ejection portion to eject liquid containing print performance improving liquid to improve the print performance of the print ink ejected from said first ejection portion by mixing with the print ink and causing the print ink to aggregate or become insoluble, said print head portion being able to be mounted in an ink-jet print apparatus; and
a seal member removably bonded to said print head portion and having an opening through a portion thereof, said seal member closing said first ejection portion and said second ejection portion so that said opening through said seal member is positioned between said first and second ejection portions.

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.

17. A method of storing a print head having a first ejection portion to eject print ink and a second ejection portion to eject liquid containing print performance improving liquid to improve the print performance of the print ink ejected from said first ejection portion by mixing with the print ink and causing the print ink to aggregate or become insoluble, said print head being able to be mounted in an ink-jet print apparatus, comprising the step of:
hermetically closing said first and second ejection portions with first and second separate elastic members of an ejection portion pressing member, the first and second separate elastic members being positioned on the ejection portion pressing member with a gap therebetween so as to form independent pressing surfaces. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
