4. Remove 3 screws and remove the process drive motor and gearbox. 5. Disconnect the wiring harness from the process drive motor. Replacement Notes: Caution If replacing the process gear drive, see "Homing the Process Gear Drive Train" on page 6-8). Caution Be careful of the wiring harness to the process drive motor and other nearby wiring. If the wires are pinched during reinstallation damage to the electronics module will occur. Ensure that the harness is routed via the cutout in the gearbox frame. Caution Before installing the process gearbox, use a slotted screwdriver to rotate the DM camshaft 360º clockwise to ensure that the head tilt system is in the home position (page 9-11). Be sure you seat the process drive motor with all three screws before torquing the screws to final tightness. Torquing the screws individually before seating all components, can put undue strain on the mounting bosses. Caution When reinstalling the gearbox, the hole in the bottom mating gear should be aligned with the arrow embossed on the ground plane. The hole in the upper mating gear should be aligned with the adjacent hole in the frame (see figure on preceding page). Remove pins from the new gearbox after installation. If the process gearbox is not re-installed with the gears in the correctly aligned and "pinned" positions, the printer will not function correctly and could be damaged. Note Ensure that the drum heater harness, Y-axis encoder harness, and the drum fan harness are replaced in the cable restraint on the gearbox. 8-56 WorkCentre C2424 Service Manual
