Liquid jetting apparatus

摘要

There is provided a liquid jetting apparatus including: a liquid jetting head including a pressure generating element and a plurality of nozzles arranged in rows in a nozzle-row direction; and a controller. The controller is configured to: determine a basic flushing amount for each nozzle; make the liquid jetting head carry out flushing with the basic flushing amount for inner-side nozzles positioned at an inner side in the nozzle-row direction; and make the liquid jetting head carry out flushing with a flushing amount larger than the basic flushing amount, for outer-side nozzles positioned at an outer side in the nozzle-row direction, of the inner-side nozzles.

1. A liquid jetting apparatus configured to jet a liquid onto a medium, comprising:
a liquid jetting head including:
a plurality of nozzles arranged in rows in a nozzle-row direction; anda plurality of pressure generating elements configured to generate pressure for jetting the liquid from the plurality of nozzles toward the medium; a controller configured to:
determine a basic flushing amount for each nozzle;make the liquid jetting head carry out flushing with the basic flushing amount for inner-side nozzles positioned at an inner side in the nozzle-row direction;make the liquid jetting head carry out flushing with a flushing amount larger than the basic flushing amount, for outer-side nozzles positioned at an outer side in the nozzle-row direction, of the inner-side nozzles; andallocate the nozzles into the outer-side nozzles based on an operation status of the liquid jetting apparatus at the time of carrying out flushing; and a humidity sensor configured to detect a humidity around the liquid jetting head; wherein the controller is configured to increase the number of nozzles to be allocated to the outer-side nozzles such that lower the humidity that has been detected by the humidity sensor, larger is the number of nozzles allocated to the outer-side nozzles.
