Reinstall note When you install the tray 2 drive gears and shaft, verify that the gears are seated on the shaft locking bars and that the shaft collars are correctly positioned in the paper-pickup gear assembly mounting bracket and printer chassis.

When you install the paper-pickup assembly, reach up inside the printer and push the rear feeder roller (see figure 68 on page 142) up into its raised position. Position the paper-pickup assembly onto the chassis (it should sit flush against the chassis) and then lower the roller into its resting position. This ensures that the feeder lever rests correctly on the large gear in the paper-pickup assembly.
