Resistance Check
Figure 3-9. Power Feed and Take-Up Motor.
1. Remove the feed and/or take-up roll from the printer.
2. Using Phillips screwdriver, remove the four screws that
secure the cradle idler from the right leg.
3. Ease the cradle idler off of the leg enough to disconnect the
motor wires from the leg harness.
4. Using a standard ohmmeter or multimeter, measure
between the + and - connections on the motor. While
manually rotating the servo motor, monitor the readings on
the meter. The acceptable range is 25-40 ohms. Typically,
the reading is 29-36 ohms.
5. If the measurement is found to be unsatisfactory, replace
the motor.
6. Perform the same procedure on the remaining motor.
