Signal Line Name Description
/SOS
Synchronizing signal generated by the SOS Sensor, which orders starting each
scanning.
/PCONT Sample/hold circuit. Low = sample (LD forced lighting) High = hold
Vref
Laser output control signal which determines or adjusts the current flowing in the
Laser Diode.
MO/DET-OUT
Laser output monitor signal which feeds back the output of laser beam emitted by the
Laser Diode (analog signal).
/LDENB
Control signal which permits the emission of light of the Laser Diode. High: Laser
Diode OFF
XP DATA+
Print image data. DATA+>DATA-: Lighting
DATA+<DATA-: Light out
XP DATA-
/ROSMOT ON
Scanner Motor Control signal which turns on and off the Scanner Motor.
Low: ON / High: OFF
/ROSMOT CLK Clock signal to the ROS MOTOR
