Testing Clutch, Motor, and Solenoid Resistance
1. Turn off the printer and disconnect the power cord.
2. With a Digital Multimeter (DMM) set for measuring resistance, test each motor’s windings
for correct resistance (disconnected from the printer). Rotate the motor’s drive shaft
slightly while taking the measurement.
