摘要： A method of removing particulates from an ink ejection face of a printhead is provided. The method comprises the steps of: (a) flooding the face with ink from the printhead, thereby dispersing the particulates into the flooded ink; and (b) transferring the flooded ink, including the particulates, onto a transfer surface moving past the face. Damage to the face is avoided since the transfer surface does not contact the face.

摘要： A inkjet printer that has an ink supply (112), a printhead integrated circuit (IC) (74) in fluid communication with the ink supply via an upstream ink line (67), the printhead IC (74), a waste ink outlet in fluid communication with the printhead IC (74) via a downstream ink line (106), an upstream shut off valve (138) in the upstream ink line (67), and, a downstream pump mechanism (114) in the downstream ink line. With a valve upstream of the printhead and a pump downstream of the printhead, the user has active control of the ink flow upstream, downstream or in the printhead IC. In the event that problems such as ink flooding, color mixing or printhead depriming occur, the user can follow simple troubleshooting protocols to rectify the situation.

摘要： A method of maintaining a printhead (10) in an operable condition is provided. The method comprises the steps of: (a) flooding an ink ejection face (12) of the printhead (10) with ink; and (b) removing the ink by blasting air across the face (12).
