Me too have the same ( it seems...) scanners and the same driver cards.
They come from an old RGY800 Laxerworld projector and are labeled at 30Kpps max. and , surelly, they are an obsolete model (year 2007).
Mirrors are a real crap and the scanspeed good for play a show is 20Kpps max.
I have any info or documentation about them: they are "U.S.O. = Unknown Scanners Objects"...
I would advise you to change them with a new good scan set (DT-40 or DT-40 Wide)

my RGB analogue projectors:
3.9 W (640/532/445) 30kpps
2.6 W (655/532/450) 30kpps
2.5 W (638/532/450) 30kpps
0.7 W (test unit)(635/532/473) 18kpps
I got them from a shogun (showtec) pro 250 rgb. These are probably also put in some neo-laser projectors as well as a lot of stuff are even still labeled with neo-laser numbers.
I'm gonna put in a dt30 instead then. I'm not gonna put in too much money in this 'pro'machine
