Here's a data sheet that I cobbled together for stepper motors found in HP LaserJet II/IID III/IIID printers. These printers used either a Japan Servo Co., Ltd. KP56QM2-001 or MINEBEA Co., Inc. - ASTROSYN 23LM-C701-01 unipolar stepper motor (HP P/N: RH7-1048-000CN). See attached data sheet in PDF format for details and pictures.
