Use the following procedure to correct the phase of the cams in the closer

screws (3).
2. Cheat the interlock for the paper transport panel.

5. Place a screw driver on one side of the cam and tap it to rotate the
cam in phase with the driven cam. Counter-clockwise if the collar side
of the book is over closed and clockwise if it is under closed.
6. Before tightening the collar, using a hex key, apply counter-clockwise
torque to the collar. This ensures that there is no slack on the top
section of the chain. While holding the chain taught, secure the M4
set screw. One must apply significant torque to properly tighten the
collar. A nut-driver (pictured bellow) can help.
7. Close the machine and run a book to examine the bind. If the problem
is still present repeat steps 2-7.
8. Reinstall the closer covers removed in step 1.
9. Return to the RAP that directed you here.
10. collar side of the book is over closed and clockwise if it is under
closed.
