20150085025 | LIQUID EJECTING APPARATUS AND PRESSURIZING/DEPRESSURIZING METHOD THEREOF - A pressurizing/depressurizing method of a liquid ejecting apparatus which includes a print head which ejects liquid, and a supply unit which supplies the liquid to the print head, the method including depressurizing/pressure accumulating in which a depressurization buffer tank is depressurized, and a pressure is accumulated; pressurizing/pressure accumulating in which a pressurization buffer tank is pressurized, and a pressure is accumulated; depressurizing in which the liquid is depressurized so that a pressure is lower than an atmospheric pressure in the supply unit using the depressurization buffer tank; and pressurizing in which the liquid is pressurized so that the pressure is higher than the atmospheric pressure in the supply unit using the pressurization buffer tank. | 03-26-2015 |
20150085032 | LIQUID EJECTING APPARATUS - A liquid circulation part has a recovery path where a liquid flows into a retaining part from a first head and a second head. The recovery path has a first merging point where the liquid flowing from the first head and the liquid flowing from the second head are merged, a first recovery path part where the liquid flowing from the first head flows into the first merging point, and a second recovery path part where the liquid flows from the first merging point. The cross-sectional area of the second recovery path part, orthogonal to a direction of flow of the liquid in the second recovery path part, is greater than the cross-sectional area of the first recovery path part, orthogonal to the direction of flow of the liquid in the first recovery path part. | 03-26-2015 |
