ABSTRACT:
The ink-jet print cartridge, which has an internal accumulator for maintaining appropriate back pressure within the pen reservoir, and a bubble generator for providing additional regulation, is refilled by a process that provides for the reestablishment of the necessary back pressure upon refilling and that prevents leakage arising as a result of the refilling operation.
