The multi sensor attached to the lower left part of the carriage consists of four LEDs and four light-receiving sensors to detect the leading edges and width of paper
and skews in it, and to adjust its registration and head height.
The multi sensor reference has the white plate attached to it, so that a reference value can be calculated during carriage height measurement by measuring the in-
tensity of light reflected upon the white plate.
(Service mode: SERVICE MODE>ADJUST>GAP CALIB)
h) Shaft cleaner
The shaft cleaner located in the right rear of the carriage helps keep the carriage shaft clean.
i) Internal unit temperature sensor
