Replacing the black gear and plate:
To make room for the new metal gear, you will need to shave off the small plastic notches on the side of the swing plate assembly. Use a razor blade or knife to shave these notches away.
Slide the metal gear into the assembly. When you replace the gear, make sure its black bearing (located in the middle of the metal gear) faces to the right, towards the inside of the printer.
Stick a strong paperclip or a thin screwdriver through the empty screw hole on the printer's side panel. Use the "tool" to line up the metal gear as it is being replaced. Rotate the gear until the tool slides all the way through the hole in the middle of the gear and holds the gear in place.
Once the metal gear is held in place by the tool, install the black disc to the right of the metal gear. The black disc has a slightly raised rim or ring on one side, the other side of the disc is flat (see below). The rim side should face the right, that is the center of the printer.
Again, use your screwdriver or paperclip as a tool to help line up the black plate, and then slide your tool all the way through so it is holding both the gear and the plate in place.
