Default NEC LSU30D 135038629001A laser diode unit

I salvaged this laser unit from a laser printer that someone had
conveniently left in a dumpster.

I'm looking for a way to make the stepper motor go, to spin the 4 sided
polygon scanning mirror, so I can swap the old laser out for a 5mW red
laser for a special effect.

This is on the back of the module:
LSU30D 135038629001A
made in Japan

the motor module inside says its also made in japan, and runs on 24V
DC, but thats no help with the pinout of the 5 conductor ribbon cable
coming out of it. - I'd rather not poke around - I don't want to fry it
- I've found that the replacement part (for the printer) is about $150.

I found out it is made by NEC, but I can't find a pinout or spec.
sheet. Does anyone know where I can find it, or how to make it go?
