Appeal No. 2003-2114
Application No. 09/757,430
12. An apparatus comprising:
a print cartridge adapted for use in an off-axis print
system, the print cartridge including an ink supply input that
provides ink from a remote ink supply;
an electronically-controlled valve coupling the ink supply
input with a local ink container within the print cartridge;
an air escape path within the local ink container, the air
escape path configured to gather air bubbles which gravitationally
separate from the ink within the local ink container; and
an air blow-off vent selectively opened to operatively couple
air in the air escape path with ambient atmosphere and selectively
closed to decouple air in the air escape path from ambient
atmosphere.
14. An apparatus according to claim 12, further comprising
an ink filter and two air escape paths, one escape path
operatively on each side of the ink filter, each escape path
configured to gather air bubbles which gravitationally separate
from the ink within the local ink container, wherein an air blow-
off vent is selectively opened to operatively couple air in each
of the two air escape paths with ambient atmosphere and
selectively closed to decouple air in all air escape paths from
ambient atmosphere.
17. An apparatus, comprising:
a print cartridge adapted for use in an off-axis print
system, the print cartridge including an ink supply that provides
ink from a remote ink supply;
a valve coupling the ink supply input with a local ink
container within the print cartridge;
an air escape path within the local ink container, the air
escape path configured to gather air bubbles which gravitationally
separate from the ink within the local ink container; and
an air blow-off vent selectively opened to operatively couple
air in the air escape path with ambient atmosphere and selectively
closed to decouple air in the air escape path with ambient
atmosphere;
