Patent ID: 6837558

Claim:
An ink-jet printer which includes a recording control circuit for controlling a recording operation, comprising: a voltage output circuit which receives power from an AC adapter and which is controllable via a terminal between an on-state for outputting a voltage and an off-state for not outputting the voltage; and a voltage output control circuit responsive to an output signal from said recording control circuit for outputting a corresponding signal to said terminal instructing the on-state or the off-state of said voltage output circuit, wherein, immediately after the initial supply of power to said voltage output circuit from said AC adapter, said voltage output circuit automatically becomes said on-state for a certain period of time corresponding to a time constant of said voltage output control circuit, and wherein said recording control circuit outputs an output signal to said voltage output control circuit such that said voltage output control circuit outputs a signal to said voltage output circuit to maintain the on-state, judges during the maintained on-state whether to cause said printer to perform a predetermined operation during said certain period of time, and outputs an output signal to said voltage output control circuit such that said voltage output control circuit outputs a signal to said voltage output circuit to become the off-state if said recording control circuit does not cause said printer to perform said predetermined operation.
