Hi,
Stepper motor failure, it means just that or it could be the
drive servo, if you can hear it running then it could well
be there is something jammed or the drive belt the drives the sensor has
come adfrift.
All a stepper motor is basically is the thing that drives the spindle
pulley, the rotator is a magnetic disc or drum mounted inside a field
coil, a complete reverse to a normal motor as we all know of... a
armature mounted inside a magnet.
A stepper motor does not use brushes since the magnetic drum does the rotating in a pair of field coils.
If you could get your hands on a broken scanner, need not be the same model
but certainly needs to be the same part numbers of the parts you are
replacing.
Hope this helps!!
