Abstract
A pump apparatus configured to circulate liquid in a printhead configured to discharge the liquid includes a drive unit configured to circulate the liquid, and a control unit configured to control operation of the drive unit based on information related to vibration of the printhead such that the printhead does not resonate due to vibration of the operation of the drive unit.
Claims15
A pump apparatus configured to circulate liquid in a printhead configured to discharge the liquid, the pump apparatus comprising:
- a drive unit configured to circulate the liquid;
- and
- a control unit configured to control operation of the drive unit based on information related to vibration of the printhead such that the printhead does not resonate due to vibration of the operation of the drive unit.
A printing apparatus comprising:
- a pump apparatus configured to circulate liquid in a printhead configured to discharge the liquid, the pump apparatus including a drive unit configured to circulate the liquid, and a control unit configured to control operation of the drive unit based on information related to vibration of the printhead such that the printhead does not resonate due to vibration of the operation of the drive unit;
- the printhead;
- and
- a carriage configured to cause the printhead to reciprocally scan.
A method for controlling a pump apparatus including a drive unit configured to circulate liquid in a printhead configured to discharge the liquid, the method comprising:
- controlling, based on information related to vibration of the printhead, operation of the drive unit such that the printhead does not resonate due to vibration of the operation of the drive unit.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method of controlling a pump apparatus including a drive unit configured to circulate liquid in a printhead configured to discharge the liquid, the method comprising:
- controlling, based on information related to vibration of the printhead, operation of the drive unit such that the printhead does not resonate due to vibration of the operation of the drive unit.
