Printing apparatus, method for controlling printing apparatus, and storage medium having first and second caps capping a liquid ejection nozzle and associated recovery operations
A printing apparatus has a moving carriage mounted on a printing head having a liquid ejection nozzle, a first cap at one end of a carriage movement range to cap the nozzle, a second cap at the other end of the range, to cap the nozzle, and a control unit having a first control in which first cap caps the nozzle or a second control in which the second cap caps the nozzle. When the carriage has anomalously stopped during printing, a recovery operation on the printing head after the first control execution is different from a recovery operation on the printing head after the second control is executed. The recovery operation includes preliminary liquid ejection at a timing other than printing, suctioning the liquid inside the first cap when the nozzle is capped by the first cap, and/or dipping the nozzle into the liquid supplied into the first cap.
1 . A printing apparatus comprising:
a carriage configured to move, and to be mounted a printing head, the printing head having a nozzle configured to eject a liquid;
a first cap disposed at one end of a range in which the carriage moves and configured to cap the nozzle;

a control unit configured to execute either a first control in which the nozzle is capped by the first cap or a second control in which the nozzle is capped by the second cap, in a case when the carriage has anomalously stopped during printing using the printing head,
wherein a recovery operation on the printing head after the first control is executed is different from a recovery operation on the printing head after the second control is executed, and
wherein the recovery operation includes at least one of:
preliminary ejection to eject the liquid from the nozzle at a timing other than printing,
suctioning the liquid inside the first cap in a state where the nozzle is capped by the first cap, and
dipping the nozzle into the liquid supplied into the first cap.
2 . The printing apparatus according to claim 1 , further comprising a supply unit configured to supply the liquid into the first cap.
3 . The printing apparatus according to claim 1 , further comprising a wiper configured to wipe a nozzle face of the printing head.
4 . The printing apparatus according to claim 1 , further comprising a conveyance roller configured to convey a print medium,
wherein the carriage anomalously stops in a case when a jam of the print medium conveyed by the conveyance roller has occurred.
5 . The printing apparatus according to claim 1 , further comprising a temperature sensor configured to sense an environmental temperature,
wherein a different recovery operation is executed depending on the environmental temperature sensed by the temperature sensor.
6 . The printing apparatus according to claim 1 , further comprising a humidity sensor configured to sense an environmental humidity,
wherein a different recovery operation is executed depending on the environmental humidity sensed by the humidity sensor.
7 . The printing apparatus according to claim 1 , wherein a wet state of the first cap is different from the wet state of the second cap.
8 . A printing apparatus comprising:
a carriage configured to move, and to be mounted a printing head, the printing head having a nozzle configured to eject a liquid;
a first cap disposed at one end of a range in which the carriage moves and configured to cap the nozzle;
a second cap disposed at the other end of the range in which the carriage moves and configured to cap the nozzle; and
a control unit configured to execute either a first control in which the nozzle is capped by the first cap or a second control in which the nozzle is capped by the second cap, in a case when the carriage has anomalously stopped during printing using the printing head,
wherein a recovery operation on the printing head after the first control is executed is different from a recovery operation on the printing head after the second control is executed, and
wherein a cleaning intensity of the recovery operation in a case when the first control is executed is lower than that of the recovery operation in a case when the second control is executed.
9 . The printing apparatus according to claim 8 , wherein a wet state of the first cap is different from the wet state of the second cap.
10 . The printing apparatus according to claim 8 , further comprising a supply unit configured to supply the liquid into the first cap.
11 . The printing apparatus according to claim 8 , further comprising a wiper configured to wipe a nozzle face of the printing head.
12 . A printing apparatus comprising:
a carriage configured to move, and to be mounted a printing head, the printing head having a nozzle configured to eject a liquid;
a first cap disposed at one end of a range in which the carriage moves and configured to cap the nozzle;
a second cap disposed at the other end of the range in which the carriage moves and configured to cap the nozzle;
a control unit configured to execute either a first control in which the nozzle is capped by the first cap or a second control in which the nozzle is capped by the second cap, in a case when the carriage has anomalously stopped during printing using the printing head; and
a pump configured to collect the liquid that is not ejected from the nozzle,
wherein a recovery operation on the printing head after the first control is executed is different from a recovery operation on the printing head after the second control is executed, and
wherein the pump is operated in a case when the carriage has anomalously stopped during printing using the printing head.
13 . The printing apparatus according to claim 12 , wherein the recovery operation includes at least one of:
preliminary ejection to eject the liquid from the nozzle at a timing other than printing,
suctioning the liquid inside the first cap in a state where the nozzle is capped by the first cap, and
dipping the nozzle into the liquid supplied into the first cap.
14 . The printing apparatus according to claim 12 , wherein a wet state of the first cap is different from the wet state of the second cap.
15 . The printing apparatus according to claim 12 , further comprising a supply unit configured to supply the liquid into the first cap.
16 . The printing apparatus according to claim 12 , further comprising a wiper configured to wipe a nozzle face of the printing head.
17 . A printing apparatus comprising:
a carriage configured to move, and to be mounted a printing head, the printing head having a nozzle configured to eject a liquid;
a first cap disposed at one end of a range in which the carriage moves and configured to cap the nozzle;
a second cap disposed at the other end of the range in which the carriage moves and configured to cap the nozzle;
