[3-Axis Stepper Controller]

Hello guys and if there-s any girls :)
I'm in "maybe" little problem.

I've made circuit like in example for Optoisolated stepper motor controller.

It looks like this

and I took a stepper motor from the scanner which have this caracteristics

Items M42SP-7
Rated Voltage DC 12V
Working Voltage DC 10.8~13.2V
Rated Current/Phase 259mA 173mA
No. of Phase 4 Phase
Coil DC Resistance   50Ω/phase±7%
Step Angle   7.5º/step
Excitation Method 2-2 Phase excitation (Unipolar driving)

and have 5 wires which are> red, black, brown, yellow and orange

i've readed little bit about wireing of steppers and that the phases(wires) of stepper must be in some strict order
so I tryed and tryed and it doesn't work, everything that i can get out of stepper is that he vibrates or nothing.

ps i have winXPpro and parallel adress is 378 checked in bios and there is something about parallel port (ECC ...)

I'm sorry for my english,
and I hope that someone is going to help me about it

Thanks to all
