Abstract
There is provided a liquid discharging apparatus including: a liquid discharging head; a cartridge attaching section in which a liquid cartridge is loaded detachably; a liquid channel; a filter provided in the middle of the liquid channel to capture a foreign substance in the liquid; a parameter deciding mechanism which, based on a cumulative use number of the liquid cartridge, decides a value of a predetermined parameter whose value becomes larger as the cumulative use number becomes larger; and a controller controlling the liquid discharging head so as to decrease an amount of the liquid discharged from the liquid discharging head per unit time as the value of the parameter becomes larger. This structure prevents the occurrence of a failure of the discharge of the liquid from nozzles.
Claims12
A liquid discharging apparatus which discharges a liquid filled in a liquid storage chamber formed in a liquid cartridge, the apparatus comprising:
- a liquid discharging head having a plurality of nozzles which are formed in the liquid discharging head and through which the liquid is discharged;
- a cartridge attaching section which is connected to the liquid discharging head and in which the liquid cartridge filled with the liquid to be supplied to the liquid discharging head is attached detachably;
- a liquid channel extending from the cartridge attaching section to the nozzles;
- a filter provided on the liquid channel at an intermediate portion thereof to capture a foreign substance existing in the liquid in the liquid channel;
- a parameter determining mechanism which, based on a cumulative usage number of the liquid cartridge, determines a value of a parameter, a value of which becomes larger as the cumulative usage number becomes larger;
- and
- a controller which controls the liquid discharging head to decrease an amount of the liquid discharged from the liquid discharging head per unit time as the value of the parameter becomes larger.
