Abstract
There is provided a printing apparatus. A cap caps an ink ejection surface of a printhead. An ink suction path is connected to the cap and sucks the ink in the cap. An ink tank stores the ink to be supplied to the printhead. An ink supply path connects the printhead to the ink tank. A first closing unit closes the ink suction path. A second closing unit closes the ink supply path. A control unit is able to execute a first control mode in which the first closing unit closes the ink suction path and a second control mode in which the second closing unit closes the ink supply path.
Claims19
A printing apparatus that includes
- a cap configured to cap an ink ejection surface of a printhead configured to eject ink,
- an ink suction path connected to the cap and configured to suck the ink in the cap,
- an ink tank configured to store the ink to be supplied to the printhead, and
- an ink supply path configured to connect the printhead to the ink tank, comprising:
- a first closing unit configured to close the ink suction path;
- a second closing unit configured to close the ink supply path;
- and
- a control unit configured to be able to execute a first control mode in which the first closing unit closes the ink suction path and a second control mode in which the second closing unit closes the ink supply path.
A control method of a printing apparatus that includes,
- a cap configured to cap an ink ejection surface of a printhead configured to eject ink,
- an ink suction path connected to the cap and configured to suck ink in the cap,
- an ink tank configured to store the ink to be supplied to the printhead, and
- an ink supply path configured to connect the printhead to the ink tank, the method comprising:
- performing a first closing process in which the ink suction path is closed;
- performing a second closing process in which the ink supply path is closed;
- and
- performing a control process in which a first control mode in which the ink suction path is closed by the first closing process and a second control mode in which the ink supply path is closed by the second closing process can be executed.
A transportation method of a printing apparatus that includes,
- a cap configured to cap an ink ejection surface of a printhead configured to eject ink,
- an ink suction path connected to the cap and configured to suck ink in the cap,
- an ink tank configured to store the ink to be supplied to the printhead, and
- an ink supply path configured to connect the printhead to the ink tank, the method comprising:
- performing a first closing process in which the ink suction path is closed;
- performing a second closing process in which the ink supply path is closed;
- performing a control process in which a first control mode in which the first closing process is performed to close the ink suction path and a second control mode in which the second closing process is performed to close the ink supply path can be executed;
- performing a first transportation process of transporting the printing apparatus upon closing the ink suction path by the first control mode;
- and
- performing a second transportation process of transporting the printing apparatus upon closing the ink supply path by the second control mode.
