h) Multi Sensor
A photo reflective type multi sensor consists of three red LEDs, one red/blue/green LED array, and three light receiving sensors and is used for media end, skew,
and width adjustment, registration adjustment, head height adjustment, and print position adjustment.
The multi sensor reference has three white plates attached to it, so that a reference value can be calculated during carriage height measurement by measuring the
intensity of light reflected upon the white plates.
(Service mode: SERVICE MODE>ADJUST>GAP CALIB.)
i) Shaft cleaner units
The shaft cleaners mounted at the left and right of the carriage are used to clean the carriage and apply oil to the shaft.
j) Internal temperature detection
A themistor for measuring the internal temperature is mounted on the carriage PCB on the rear of the head holder.
