Head management sensor
Pump cam sensor
As the cam rotates, it shields the sensor light of the photointerrupter-based pump cam sensor or allows it to be
transmitted. The status of the purge unit, such as capped, suction, and wiping, is detected in a combat ion of the
status of detection by the pump cam sensor and the control of purge motor rotation by the pump encoder sensor.
