Abstract
A printing apparatus includes: a supply unit configured to supply a cleaning liquid into the cap; a discharge unit configured to discharge the liquid from the cap; and a control unit configured to execute a discharge operation to cause the discharge unit to discharge an amount of the liquid smaller than a supply amount of the cleaning liquid supplied into the cap by the supply unit.
Claims17
A printing apparatus comprising:
- a cap configured to cap a print head having an ejection orifice from which an liquid is ejected;
- a supply unit configured to supply a cleaning liquid into the cap;
- a discharge unit configured to discharge the liquid from the cap;
- and
- a control unit configured to execute a discharge operation to cause the discharge unit to discharge an amount of the liquid smaller than a supply amount of the cleaning liquid supplied into the cap by the supply unit, wherein,
- in a case where a liquid amount discharged from the ejection orifice is a first amount, the control unit executes the discharge operation in a manner different from a manner in a case where the liquid amount is a second amount which is larger than the first amount.
A method for controlling a printing apparatus, the printing apparatus including
- a cap configured to cap a print head having an ejection orifice from which an liquid is ejected,
- the control method comprising:
- supplying cleaning liquid into the cap;
- discharging liquid from the cap;
- and
- executing a discharge operation to discharge, in the discharging, an amount of liquid smaller than a supply amount of the cleaning liquid supplied into the cap in the supplying.
A non-transitory computer readable storage medium storing a program for causing a computer to perform a method for controlling a printing apparatus, the printing apparatus including
- a cap configured to cap a print head having an ejection orifice from which an liquid is ejected,
- the control method comprising:
- supplying cleaning liquid into the cap;
- discharging liquid from the cap;
- and
- executing a discharge operation to discharge, in the discharging, an amount of liquid smaller than a supply amount of the cleaning liquid supplied into the cap in the supplying.
