Claim 0:
1. An inkjet printer, comprising:
a head including a nozzle from which a liquid is injected; a cleaner to perform a cleaning operation of to cause the liquid to be discharged from the nozzle;
a waste liquid tank to which the liquid discharged by the cleaning operation is recovered from the cleaner;
a support table supporting the waste liquid tank, the support table being displaceable in accordance with a weight of the liquid in the waste liquid tank, such that the support table is at an initial position in a state where the liquid is not recovered to the waste liquid tank, is displaced to a first position when a weight of the waste liquid tank and the liquid in the waste liquid tank reaches a first threshold value, and is displaced to a second position when the weight of the waste liquid tank and the liquid in the waste liquid tank reaches a second threshold value larger than the first threshold value;
a first sensor to detect that the support table has reached the first position;
a second sensor to detect that the support table has reached the second position;
a first determinator to determine that the waste liquid tank is in a near-end state when the support table is detected by the first sensor to have reached the first position;
a second determinator to determine that the waste liquid tank is in an end state when the support table is detected by the second sensor to have reached the second position; and, a notifier to notify a user of the near-end state when the first determinator determines that the waste liquid tank is in the near-end state.
