c) Pumps
In this printer, tube pumps press on the ink tubes using push rollers to produce
negative pressure and enable suction of the ink. Two rollers are used to press a
single tube one after the other to allow flexible control over the ink suction volume.
The rotation timing of the push rollers in the suction pump is detected by the pump
home position sensor, and the rotation speed is controlled by the driving of the
pump motor (stepping motor).
d) Sensors
Sensors are located in the purge unit for detecting the status of the printer
components.
