I've found there's sometimes a mix of both, especially in "all-in-one" type devices. I've never seen a scanner that didn't have a stepper motor though. I'm working on a McWire CNC, and I tried to use steppers from an old printer. They apparently aren't strong enough, though I haven't given up yet. If the stepper is geared down I may have better luck, and a laserjet fuser I found had a very highly geared down stepper motor. I'll try that next and keep an eye out for more trash laserjet printers. So, my answer to your question is: maybe. Power is the big issue, and personally I'm thinking torque can compensate if you can keep any gearing-down mechanisms in tact. The older the printer/copier/scanner/electric typewriter that you find, the more likely it is to have big motors that may work for CNC. Good luck!
