Geometric features to minimize free ink in an ink supply fluid interconnect

In an ink reservoir having an exterior wall and a hollow interior configured to contain ink-permeable foam, a fluid interconnect port comprising:

• a hole formed through the exterior wall into the hollow interior, the hole having an inside surface;
• means on the inside surface of the hole contiguous to the hollow interior to accumulate ink by capillary attraction;
• and
• capillary break means on the inside surface of the hole immediately adjacent to the means to accumulate ink by capillary attraction.

An ink reservoir, comprising:

• an exterior wall and a hollow interior, the hollow interior containing ink-permeable foam;
• a fluid interconnect port comprising
• a hole formed through the exterior wall into the hollow interior, the hole having an inside surface;
• the inside surface of the hole contiguous to the hollow interior forming a capillary accumulator;
• and
• the inside surface of the hole immediately adjacent to the capillary accumulator forming a capillary break.

In the art of ink jet printing, a method of preventing ink from contaminating the fingers or clothing of an ink reservoir installer during the installation process, the ink reservoir having an exterior wail and a hollow interior, the hollow interior containing ink-permeable foam;

• the reservoir further having a fluid interconnect port forming a hole through exterior wail to the hollow interior, the interconnect port sealed during shipping and storage with a removable tape, comprising the steps of:
• configuring the fluid interconnect port contiguous to the hollow interior to form a capillary accumulator;
• and
• configuring the fluid interconnect port immediately adjacent to the capillary accumulator to form a capillary break.
