Replacement
NOTE: Before installing the Process Drive, perform the Manual Printhead Parking procedure
(ADJ 1.4) and Wiper Blade Alignment procedure (ADJ 1.1) to put the Printhead and Wiper
Assembly in the home position.
1. Slightly insert the Process Drive while rotating the Process Drive towards the left hand
side until the flange sits behind the gear (Figure 5).
2. Before tightening the Process Drive mounting screws, align the holes in the Process Drive
flange with the mounting bosses on the frame, seat the Gears, and press the Process
Drive tightly against the frame (Figure 1).
CAUTION
Do not use the screws to pull the Process Drive into alignment.
3. Next, seat all three screws before torquing the screws to a final tightness of 12 in-lbs.
Tightening the screws individually before seating all three can put undue strain on the
mounting bosses.
