Okay, Here are the Two Motors I found from EPSON Printer.. I got them from Printer Repair Shop for $6US.. One is Bipolar 3.7 degree/Step and Other is Unipolar with 1.8 degree/Step..
I didn't found the complete specifications from internet...
The small Bipolar (4-wires) one is STH-39H112 and a little biger Unipolar (5 wires) is STP-42D221-01
Attached you can find the resistance table of 5-wire motor..Can someone help me can i control this stepper with Arduino+Adafruit shield?
