Laser Scanning Unit

I have used LCU (Laser Scanning Unit) salvaged from the old HP LaserJet 6L printer. It has 4 side polygon mirror with motor controlled by AN8247SB chip - unfortunately I haven't manage to find a datasheet.

Connector pinout according to the LaserJet 6L service manual.

Unfortunately it is not possible to use LSU with F-theta lens as it is - it is designed for IR laser and it isn't possible to focus in the both direction for 405nm laser.
