Belt, Paper Feed Timing317Belt, Paper Feed TimingRemoval1. Prepare the printer for maintenance (page 313).2. Cabinet Model: Remove the paper guide assembly (page 348).Pedestal Model: Remove the top cover assembly (page 327).3. Remove the timing belt cover by squeezing the front and back to release the plastic tabs from the slots in the side plate(page 400, Figure 39, item 7).4. Loosen (do not remove) the paper feed motor mount screws (page 416, Figure 46, item 10).5. Work the paper feed timing belt off the paper feed motor pulley and the splined shaft pulley.Installation1. Work the paper feed timing belt onto the paper feed motor pulley and the splined shaft pulley.2. Using the straight end of a force gauge, apply 15 pounds (66.7 N) of pressure to the paper feed drive motor near themounting base of the motor. Use the splined shaft to steady the gauge.3. Reduce tension to 12 pounds (53.4 N) and torque the paper feed motor mount bolts to 18 ± 2 inch-pounds (2.03 ± 0.23N•m).NOTE: Belt tension is correct if the belt deflects 1/8 inch midway between the pulleys.4. Snap the timing belt cover into the slots in the side plate (page 400, Figure 39).5. Cabinet Model: Install the paper guide assembly (page 348).Pedestal Model: Install the top cover assembly (page 327).6. Return the printer to normal operation (page 314).
