A fluid ejecting apparatus includes an ejection head having an ejection face formed with an ejection nozzle that ejects fluid, a detection device having a detector that is arranged to face the ejection face with a predetermined gap provided therebetween and to which the fluid ejected from the ejection nozzle is supplied, the detection device outputting a detection signal in response to the fluid ejected from the ejection nozzle, a processing unit that obtains information on the viscosity of the fluid on the basis of the detection signal, a measurement device that measures an elapsed time from a reference time and outputting the measured value, a maintenance device capable of performing maintenance of the ejection head, and a control device that controls the maintenance device on the basis of the measured value output from the measurement device. The measurement device changes the measured value to be output on the basis of the information obtained by the processing unit.
