ABSTRACT:
In order to stabilize a performance of a pump employed for processing in an inkjet printing apparatus such as sucking ink from a printing head with a low cost configuration and without the need of using any specific detecting unit, the following configuration is employed. Namely, a tube pump having a member with a curved surface aligned with a flexible tube for supporting the tube and a roller which moves while pressing (squeezing) the flexible tube is driven with a DC motor. To keep revolutions always constant, a current PWM control is employed for changing a power applied to the motor according to load fluctuations, and a phase of the roller is determined based on the current PWM value to manage a pressure generated by the pump and a discharge rate.
