Printing apparatus and method for determining service life
To provide a printing apparatus and a method for determining a service life of a cleaning mechanism, capable of more accurately determining a service life of a cleaning mechanism. For the purpose, a service life of a recovery unit is determined by multiplication of a number of times a blade wipes a face surface by a coefficient different depending on a quantity of liquid adhering to the face surface.
1. A printing apparatus, comprising:
an ejection unit configured to eject liquid from ejection ports;
a blade configured to wipe an ejection port surface provided with the ejection ports; and
a cleaner that performs cleaning of the blade;
an accumulative unit for storing accumulative information on an operation performed immediately before the blade wipes the ejection port surface from among a plurality of operations that can be performed immediately before the blade wipes the ejection port surface; and
a notifying unit for notifying a service life of the cleaner based on an accumulative result of the accumulative unit.
2. The printing apparatus according to claim 1 , wherein:
the notifying unit notifies a service life of the blade based on the accumulative result.
3. The printing apparatus according to claim 1 , wherein:
the notifying unit changes an operation of the apparatus according to the accumulative result of the accumulative unit.
4. The printing apparatus according to claim 1 , wherein:
the recovery unit includes a cap covering the surface of the ejection unit.
5. The printing apparatus according to claim 1 , wherein:
an operation performed immediately before wiping the ejection port surface includes at least one of wiping of the ejection port surface by the blade, ejection of liquid from the ejection port, suction of liquid from the ejection port, and pressurization inside the ejection unit.
6. A method for notifying a service life, comprising:
a wiping step of wiping an ejection port surface provided with an ejection port ejecting liquid with a blade;
a cleaning step of cleaning the blade by a cleaner;
an accumulation step of storing accumulative information on an operation performed immediately before the blade wipes the ejection port surface from among a plurality of operations that can be performed immediately before the blade wipes the ejection port surface; and
a notification step of notifying a service life of the cleaner based on an accumulative result of the accumulation step.
7. A printing apparatus, comprising:
an ejection unit configured to eject liquid from ejection ports;
a blade configured to wipe an ejection port surface provided with the ejection ports;
a cleaner that performs cleaning of the blade;
an accumulative unit for accumulating a result of performing weighting based on a type of operation performed immediately before the blade wipes the ejection port surface; and
a notifying unit for notifying a service life of the cleaner based on an accumulative result of the accumulative unit.
8. The printing apparatus according to claim 7 , wherein:
the accumulative unit performs weighting based on an interval from a preceding execution of cleaning of the blade by the cleaner.
9. The printing apparatus according to claim 7 , wherein:
the accumulative unit performs weighting according to a series of a plurality of operations performed just before the blade wipes the surface.
10. The printing apparatus according to claim 7 , wherein:
the notifying unit performs weighting by setting a coefficient and notifies a service life of the cleaner based on an accumulated value of values obtained by multiplication of a number of times the blade wipes the ejection port surface by the coefficient.
11. The printing apparatus according to claim 7 , wherein:
an operation performed immediately before wiping the ejection port surface includes at least one of wiping of the ejection port surface by the blade, ejection of liquid from the ejection port, suction of liquid from the ejection port, and pressurization inside the ejection unit.
12. A method for notifying a service life, comprising:
a wiping step of wiping an ejection port surface provided with an ejection port for ejecting liquid with a blade;
a cleaning step of cleaning the blade by a cleaner;
an accumulation step of accumulating a result of performing weighting based on a type of operation performed immediately before the blade wipes the ejection port surface; and
a notifying step of notifying the service life of the cleaner based on information accumulated in the accumulation step.
