7. LSU Control Circuit
The laser control signals are described below.
Actual data is sent from SC PCB to LSU.
VIDEO+
:
Actual data is outputted by these 2 signals.
VIDEO-
nS/H
:
Laser Power Sample/Hold Timing Signal.
nHSYNC :
This horizontal synchronization signal transmitted from the Beam Detection
Sensor sets the horizontal position of the laser beam as it crosses the OPC Drum.
nLDON
:
The LSU is activated when this output signal is LOW. If an error occurs, the
nLDON output signal level goes High and the LSU is deactivated.
pLDCTL :
This signal turns ON the laser output to activate nHSYNC signal.
VCON
:
This is the Analog Voltage for adjusting Laser output power.
nPMCK
:
This is the Polygon Motor Drive Clock.
nPMRDY :
When the Polygon Motor speed is constant, the nPMRDY is at a Low output
signal level.
nPMON
:
This is the Polygon Motor Control Signal. The Polygon Motor rotates when the
nPMON output signal level is LOW.
