Abstract
An apparatus includes a bypass flow path between an ink supply port and a vent port and a primary flow path between the ink supply port and an ink delivery port. A first flow velocity of the bypass flow path is higher than a second flow velocity of the primary flow path. The first flow velocity induces bubbles to travel via the bypass flow path instead of the primary flow path.
