Stepper Motor Legality for 2012 Robots

We are throwing around the idea of using a stepper motor on our shooter. The one thing we are wondering if it is a legal motor for this year. I have not found much documetnation from previous years about this type of motor. The rules this year don't state this motor specifically being allowed. But the rules do say that motors from kits of parts from previous years CAN be used.

Any help?

Thanks

The only motors and actuators permitted on 2012 FRC Robots include:
A. up to 4 CIM motors (part #FR801-001, M4-R0062-12, AM802-001A, 217-200 or PMR25R-45F-1003),
B. up to 4, in any combination, of the BaneBots motors provided in the KOP (acceptable part numbers are
M7-RS775-12, M7-RS775-18, M5-RS550-12, M5-RS550-12-B, and M3-RS395-12),
C. up to 2 window motors (acceptable part #s are 262100-3030 and 262100-3040),
D. up to 2 FisherPrice motors (acceptable part #s are 00968-9013, 00801-0673, and 00968-9015),
E. up to 2 AndyMark motors (acceptable part # is am-0912),
F. up to 2 AndyMark gearmotors (acceptable part # is am-0914),
G. up to 2 Denso throttle control motors (acceptable part # AE2351000)
H. up to 2 VEX motors (acceptable part # 276-2177)
I. up to 2 window lift, seat, windshield wiper or door motors obtained through either the FIRST-Automotive
Recyclers Association partnership or from a prior years’ KOP.
J. electrical solenoid actuators, no greater than 1 in. stroke and rated at no greater than 10 watts continuous
duty at 12V,
K. drive motors or fans that are part of a speed controller or COTS computing device
L. an unlimited number of COTS servos with a maximum power rating of 4W each at 6V.

I think that list is very explicit on what is allowed, including part numbers. If you can find a stepper motor from the ARA that's a lift, seat, wiper, or door motor, then you're good to go. Otherwise, I don't think any of those are stepper motors.

The only rule that mentions previous year's KoP is part I, which specifically limits it to the lift, seat, wiper, and door motors that have been available in the past. I don't think that covers a printer motor.
