Ink container having a guide feature for insuring reliable fluid, air and electrical connections to a printing system
First Claim
1. A replaceable ink container for providing ink to an off-axis printing system, the printing system responsive to electrical signals from the replaceable ink container for controlling printer parameters, the replaceable ink container comprising:
- a housing having a leading edge and a trailing edge relative to a direction of insertion of the ink container into the printing system;
a fluid outlet disposed toward the leading edge, the fluid outlet configured for fluid connection to a hollow needle associated with the printing system, the hollow needle extending in a direction opposite the insertion direction;
a plurality of electrical contacts disposed on the housing, the plurality of electrical contacts configured for engagement with complementary electrical contacts associated with the printing system; and
a guide member positioned on the leading edge of the housing proximate the plurality of electrical contacts, the guide member extending from the ink container along the insertion direction, the guide member configured for engaging a tapered guide member receiving slot associated with the printing system for repositioning the complementary electrical contacts relative to the hollow needle to ensure proper alignment of complementary electrical contacts with the plurality of electrical contacts during insertion of the ink container into the printing system.

Abstract
The present invention is a replaceable ink container for providing ink to an off-axis printing system. The printing system responsive to electrical signals from the replaceable ink container for controlling printer parameters. The ink container has a leading edge and a trailing edge relative to a direction of insertion of the ink container into the printing system. The replaceable ink container includes a fluid outlet disposed toward the leading edge. The fluid outlet is configured for fluid connection to a hollow needle associated with the printing system The hollow needle extends in a direction opposite the insertion direction. Included in the ink container is a plurality of electrical contacts disposed on the ink container. The plurality of electrical contacts are configured for engagement with complementary electrical contacts associated with the printing system Also included in the ink container is a guide member extending from the ink container along the insertion direction. The guide member is configured for engaging a tapered guide member receiving slot associated with the printing system. This engaging repositions the complementary electrical contacts relative to the hollow needle to ensure proper alignment of complementary electrical contacts with the plurality of electrical contacts during insertion of the ink container into the printing system
