Abstract
A triggerable ink transfer system that simultaneously transfers ink from a plurality of ink preload chambers to corresponding load chambers and ink reservoirs is disclosed. The delivery system permits an untrained operator to safely load ink without inadvertently interchanging different types (e.g. colors) of ink, and without inadvertently overfilling any of the ink reservoirs. A processing unit that coordinates ink delivery system monitoring and control features is in communication with an operator interface unit that provides ink loading instructions to the operator.
