Ok started stripping down the two scanners I have and one of them has a 5 wire motor! a quick search of the interweb to check its a stepper, then a bit of googlefu to out if ramps 1.4 will run a unipolar stepper (hark at me sounding like I know what I'm talking about) and I found a few blog posts on converting a them to 4 wire, so quick few cuts with a craft knife and i have a nice 4 wire motor.
red wire goes between top middle and bottom middle pins connection cut so just need to remove red wire.
