Abstract
An ink cartridge storage structure and method provide consistent print density and quality by mixing the ink when the cartridge is removed from the packaging and installed to a printer for use. An ink-filled ink cartridge with an ink supply port installable to the head of a printer is stored inside an individual box made to hold the ink cartridge. The ink cartridge is stored inside the individual box so that the ink supply port is at the top when the box is in the normal upright position.

an ink path configured to release ink when said cartridge is installed to said recording head; and
an air path that releases air into said ink path based on a negative pressure in said ink path.
-
-
9. The ink cartridge structure according to claim 8, wherein said air path comprises an air valve that permits air intake via an air hole when said cartridge is installed to said recording head.
-
10. The ink cartridge structure according to claim 8, wherein said air flows into a storage chamber of said ink path, based on said negative pressure, to displace discharged ink.
-
11. The ink cartridge structure according to claim 8, wherein said air path of said cartridge comprises:
-
an airflow channel within said cartridge, configured to increase airflow resistance;
a wide, recessed channel connected to said airflow channel; and
an air permeable film stretched over said air path to form an air permeable chamber in said cartridge.
-
-
12. The ink cartridge structure according to claim 11, wherein said airflow channel comprises a zigzag channel.
-
13. An ink cartridge storage method comprising:
-
positioning an ink-filled ink cartridge having an ink supply port and an ink storage part for holding only ink in a packaging for storing the ink cartridge, wherein the ink cartridge is stored in an orientation different from a position in which the ink cartridge is used, wherein the ink cartridge is stored in the packaging so that the ink supply port is positioned at a top side, and wherein the ink inside the ink cartridge is a pigment ink. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
an ink path releasing ink when said cartridge is installed co said recording head; and
an air path releasing air into said ink path based on a negative pressure in said ink path.
-
-
18. The method according to claim 17, wherein said air path releasing comprises an air valve permitting air intake via an air hole when said cartridge is installed to said recording head.
-
19. The method according to claim 17, said air path releasing comprising said air flowing into a storage chamber of said ink path, based on said negative pressure, to displace discharged ink.
-
20. The method according to claim 17, wherein said air path releasing comprises:
-
increasing airflow resistance via an airflow channel within said cartridge; and
transporting air through a wide, recessed channel connected to said airflow channel, wherein an air permeable film is stretched over said air path to form an air permeable chamber in said cartridge.
-
-
21. The method according to claim 20, wherein said increasing airflow resistance comprises channeling air through a zigzag channel.
- 22. An ink cartridge storage method comprising a step of positioning an ink-filled ink cartridge having an ink supply port and an ink storage part for holding only ink in a packaging for storing the ink cartridge, wherein the ink cartridge is stored with the ink supply port positioned on a first side and wherein when the ink cartridge is installed for usage, the ink supply port is positioned on a second side opposite of said first side.
