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.

Solenoid
Head Maintenance Clutch 186 ohms +/- 15%
Paper-Pick Clutch 186 ohms +/- 15%
Deskew Clutch
Process Drive Motor 2.85~3.85 ohms (Difficult to measure due to variability at the
