Abstract
In an inkjet printer having primary power-turn-on means for physically supplying power to the printer and secondary power-turn-on means for bringing the printer into a state where functions are enabled, ink consumption due to a suction recovery processing is reduced. The number of times that the secondary power supply is on is counted. The count value is stored in a non-volatile memory. It is judged whether the count value is above a predetermined value when the secondary power supply becomes on, if yes, the recovery processing is executed. The count value and the contents of the memory are then cleared. The counting is prohibited till primary power supply is off. As the above contents is retained even after the primary power supply is off, necessity of recovery processing when the secondary power supply becomes on is judged based on the state before the primary power supply was off.
