I do not have instructions for printer assembly or wiring. Please reference your printer manual for instructions. These motors come with a conventional four-wire color coded harness which should be compatible with most electronics.

------------------------
2V is the correct rating and is very common. Current control is required with your motor drivers to use higher voltage, such as 12 volts. Pololu stepper drivers with overcurrent protection work great.

Power and current: All stepper motors will have certain specifications for voltage and current (typically 2.8 V and 1.68 A); as long as the stepper driver/controller does current control, you can use any supply voltage greater than the motor's rated voltage. In fact, a large difference is advantageous to the top speed of the motor.
