3.1.3.5 LSU
LSU is consist of LD(Laser Diode) and polygon motor control. When the controller generate the printing signal LD will
turn on and Polygon motor starts.If the receiving part in LSU detect the beam and then Hsync is generated. When the
rotation of poygon motor is steady, it is time of LSU ready status for printing. If either of two condition is not satisfied,
LSU error is expected.
