Carriage HP sensor
The photointerrupter-based carriage HP sensor detects the home position of the carriage.
Installed on the right side plate of the printer, the sensor detects an edge of the carriage home position on the carriage unit under carriage movement control.
The printer establishes the carriage home position from the position at which its edge is detected as a reference position.
Linear encoder sensor
Mounted on the back of the carriage, the linear encoder detects the position of the carriage from a slit in the linear scale during its movement.
Lift cam sensor
A photointerrupter-based sensor. After the sensor light is shielded by the flag, the lift motor is driven by a predetermined number of pulses to regulate the separation
between the printheads and platen automatically.
Ambient temperature sensor
The thermostat-based ambient temperature sensor mounted on the carriage PCB detects the ambient temperature to which the carriage is exposed.
The resistance of the thermistor that varies as a function of temperature changes in the printer is transmitted to the main controller via the carriage PCB.
The ambient temperature is used to help calibrate the head temperature sensor and detect abnormal ambient temperatures.
Head temperature sensor
The head temperature sensor detects the temperature of the printhead.
The printhead temperature is transmitted to the main controller via the carriage PCB.
The printhead temperature is used to help control the head drive and detect abnormal printhead temperatures.
Printhead contact detection
The printhead contact detects the status of printhead installation by electrical means.
The contact detects the status of contact from voltage changes in the flexible cables on the carriage side that come into contact with two terminals of the printhead
with remote contact surfaces, the power terminals and GND terminal.
