Hi. I need help with 3 stepper motors.
I searched the forums, datasheet sites, epson and oki web sites and all over the internet but i couldn't find the specifications.

The motors have a serial number, model and a brand name printed on them:

Epson EM-434, 192L05b
OKI EM-437, 1816AA1
OKI EM-546, VY*not readable*AP2

I dont have the rest of the printers or the controllers model. (I disassemble the printers long ago).

I hope someone can help me.
