Abstract
There is provided a head cleaning method in a liquid discharging apparatus which includes a head, a storage section that stores liquid, a circulation flow path that includes a first flow path which supplies the liquid from the storage section to the head and a second flow path which refluxes the liquid from the head to the storage section, a circulation pump, and a wiping section. The head cleaning method includes: a first step of setting a flow rate per unit time of the liquid which flows through the circulation flow path to a first flow rate which is greater than a flow rate in a case in which the liquid is discharged to the recording medium; a second step of the wiping section performing the wiping process after the first step; and a third step of setting the flow rate per unit time of the liquid which flows through the circulation flow path to a second flow rate which is lower than the first flow rate after the second step.
