Multisensor

The photoreflector-based multisensor consists of four LEDs (red, blue, green, infrared) and two light-receiving

sensors to detect the leading edges and width of paper and skews in it, and to adjust its registration, head height

and calibration.

At head height adjustment, the two light-receiving sensors detect infrared light reflected upon the paper to work

out the head height form differences in its measurement.

Service mode: After SERVICE MODE > ADJUST > GAP CALIB. has been carried out, pass paper to make

sure that it is detected properly.

Carriage cover sensor

The photointerrupter-based carriage cover sensor detects the opening and closing of the carriage sensor.

When the carriage cover is closed, the sensor light is shielded by the sensor arm, enabling the sensor to detect

that the carriage cover is closed.

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 printhead and platen automatically.

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.

Ambient temperature sensor

The thermostat-based ambient temperature sensor mounted on the head relay 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 the

main controller via the carriage relay 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 relay PCB.

The printhead temperature is used to help control the head drive and detect abnormal printhead temperatures.
