Laser Unit (LSU) Control Circuit
The laser control signals are described below.
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.
nVIDEO
This is the actual Data Signal. The Laser is ON when the nVIDEO output signal level is LOW.
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.
nPMON
This is the Scanner Motor Control Signal. The Scanner Motor rotates when the nPMON output signal level is LOW.
nPMRDY
A Phased-Lock Loop (PLL) circuit keeps the Scanner Motor speed constant when the nPMRDY is at a Low output signal level.
nPMCK
This is the Scanner Motor Clock.
