A fluid discharging apparatus includes an accommodation unit that accommodates a fluid, a discharge port that communicates with the accommodation unit, a moving object that moves in a first direction toward the discharge port and in a second direction away from the discharge port in the accommodation unit, and a control unit that controls driving of the moving object. The control unit performs discharging processing and moving processing. In the discharging processing, the discharge port is opened by moving the moving object from a closed position at which the discharge port is closed, in the second direction, and then the fluid is extruded and discharged from the discharge port by moving the moving object in the first direction. In the moving processing, the moving object is moved in the second direction during a period when the fluid is discharged from the discharge port in the discharging processing.

A printing apparatus includes a detection unit that is arranged to face an ejecting surface on which a plurality of nozzles of a printing head that ejects liquid droplets are arrayed, and detects an ejecting condition of the liquid droplets, a recovery unit that recovers an ejecting condition of nozzles of the printing head; and a control unit that determines whether to perform or skip inspection of the ejecting condition by the detection unit based on a state of each of the nozzles of the printing head, and controls a nozzle for which the inspection of the ejecting condition is determined to be skipped so as to perform the inspection of the ejecting condition by the detection unit after the recovery unit recovers the ejecting condition of the nozzle.

Disclosed is a method of providing adjustment data for a droplet deposition head (such as a printhead), or a data processing component therefor. The method makes use of test data, which has been collected by operating the droplet deposition head (or a test droplet deposition head of substantially the same construction, e.g from the same batch), using a set of test waveforms, at a number of frequencies within a test range, and by recording the volume and velocity of the thus-ejected droplets, with these recorded values (vol.sub.r, vel.sub.r) being represented within the test data. Each of the set of test waveforms includes a basic drive waveform and a number of adjusted drive waveforms, each of which corresponds to the basic drive waveform, but with a particular waveform parameter adjusted by a corresponding amount. This waveform parameter is a continuous variable, such as pulse width or pulse amplitude. The method further includes, determining adjustment values corresponding to a

Liquid supplied from the first storage chamber to the second storage chamber through an inlet port is supplied from the second storage chamber to the recording portion through an outlet port. The wall portion partitions an internal space of the second storage chamber into a first region including the liquid inlet port and a second region including the detected portion. The wall portion extends upward than the liquid inlet port and the detected portion and downward than the liquid inlet port and the detected portion. Communication between the first region and the second region is allowed through upper and lower communication portions. The upper communication portion is positioned upward than the liquid inlet port and the detected portion.

A printing device comprises a droplet generator for generating a droplet of printing fluid, a droplet detector for detecting a generated droplet of printing fluid, and a controller. The droplet detector is moveable along an axis. The controller is to cause the droplet detector to be positioned at a known location along the axis, cause the droplet generator to generate a droplet, receive a measurement signal from the droplet detector, and determine a location of the droplet generator based on the received measurement signal and the known location.
