Description: This stepper motor is from an HP Scanjet 2400 flatbed scanner. It operates on 12-volts and is driven by a ULN2003 Darlington transistor array chip. Small stepper motors like this usually have very low torque, to increase the torque and the resolution, a reduction gear mechanism is often added. The gears cause some backlash though.
