Tilt mitigation methods to control reservoir ink level and printhead pressure

摘要

An ink level control system includes a first dividing wall that divides a reservoir of a printhead into a first chamber and a second chamber. The first and the second chambers are each connected to the ink passages of the inkjet stack by an ink port. The first dividing wall includes an opening that connects the first chamber and the second chamber to enable ink to pass therebetween. The opening is located a predetermined distance above the bottom surface of the reservoir. An ink diverter is associated with the inlet opening that directs ink received through the inlet opening to one of the first and the second chambers in response to the reservoir being tilted in a first direction, and directs ink to the other of the first and the second chambers in response to the reservoir being tilted in a second direction.
