Abstract:
A recording device comprising:a recording head that records on a recording medium by ejecting ink when applied with energy;at least one component that is driven by a corresponding at least one drive source when the corresponding at least one drive source is applied with energy;an environment detector that periodically detects an environment in which the recording head is disposed and outputs an analog signal corresponding to the environment;a converter that converts the analog signal into a digital signal, noise being introduced into the analog signal from at least one of the recording head and the at least one drive source, said noise generated when at least one of the recording head and the at least one drive source is applied with energy; anda controller that periodically detects whether the recording head and a predetermined one of the at least one drive source are being applied with energy, the controller receiving the digital signal from the converter only at times when the controller detects that the recording head and the predetermined one of the at least one drive source are not being applied with energy, the controller controlling application of energy to the recording head by changing energy used to eject ink based on the received digital signal.
