ABSTRACT:
The present invention is directed to an ink liquid supply system wherein a subtank is interposed between an ink liquid reservoir and a pump in the ink liquid supply system for an ink jet system printer. Waste ink liquid not contributing to the printing operation is collected by a beam gutter and returned to the subtank. A first coarse filter and a second fine filter are disposed within the subtank in order to remove dust and bubbles included within the ink liquid introduced into the subtank.
