Identify stepper's nominal voltage

[luck09]

Hello all,
I have two stepper motors.
The first one is
P/N RH7-1339 03
Type 23KM-K379-G1
The second one is
RH7-1336 03
STP-42D236

I want to find out their nominal voltages, but can not google them. Could you tell me something about them? Also, I don't understand some symbols like P/N, STP, etc.
Thank you very much!

Can you upload a photo?

Where is the steppers placed? Is it a printer? What is the supply voltage og the equipment the steppers is mounted on?

What resistance can you measure between pins?

I think the photo is same as here
**broken link removed**

These motors are unipolar steppers, 6 wires.
Yes. I think they are in printers, but I can not find out these printers now.
I remember that one motor (RH7-1336 03) has resistance 5.3 and 10.3 Ohm. Another one I don't remember exactly, I will check again tomorrow.
If you could provide specification based on these information please help me.
Thank you!

BTW.
P/N stands for: Part Number
and
STP is most likely just STePper ..

Thank you so much! I tried but can not find out.

No worries. It will probably run just fine at 5 volt. If you experience that torc isn't strong enough, you can always rise the voltage. Anyway, check the temperature by hand to ensure it doesn't run too hot.
