Re-installation

  1. Before you re-install the shift unit, turn the cam shaft on the right until its flat edge is facing up and level.
  2. Turn the shift unit gear so the flat end of its shaft is facing up and parallel with the end of the flat end of the cam shaft .
  3. Slowly, set the shift unit [A] with the flat side of the shaft facing up.
  4. Slowly, push in the front drawer until it stops.
  5. At the back of the machine, check the positions of the shaft ends.
  6. If the flat sides of the shaft ends are facing up and parallel [A], they are positioned correctly.
  7. If one or both are not aligned correctly [B], one or both must be adjusted.

    • The flat sides of both of these shafts must face up and be parallel [A].
    • If either or both are even slightly out of position, this will cause paper jams in the registration unit.

  8. Pull out the front drawer again until it stops.
  9. If you need to adjust the positions of the shaft ends, lift the shift unit [A] up slightly, and then turn the gears [B] until they are up and level.
  10. Slowly, push in the front drawer until it stops.
  11. At the back of the machine, check the positions of the shaft ends and make sure the flat sides are facing up and parallel.
  12. Pull the drawer out again until it stops.
  13. Re-install the removed shaft.
  14. After re-installation of the shaft, once again push the drawer into the machine and then check the positions of the shaft ends to make sure that they have not slipped out of alignment.
  15. Re-install the transfer timing motor, and then finish the re-installation.
