2.11.7 Replacing the original feed magnetic clutch
Turn off the main switch, and remove the ADF rear
cover (7 plated screws).
CAUTION
The ADF rear cover is made of metal. So, the
cover may touch electric elements on the
boards shorting them out when you remove the
cover. Be sure to turn off the main switch when
you remove the ADF rear cover.
1. Remove the ADF control board.
CAUTION
• Before installing the board, be sure to
connect the three connectors on both the
front and back of the board.
• Be sure not to damage electric elements on
the board.
• Be sure not to cut the harnesses by pulling
the board or rubbing the harnesses with the
edges of any brackets or plates.
• Do not pull the fiber optics cable when you
disconnect it from the ADF control board.
Grasp its connector using pliers and pull it
out.
2. Remove the magnetic clutch bracket (2 screws
and one E-ring).
3. Slide and pull out the magnetic clutch.
CAUTION
Take care not to lose the inside collar and
parallel key.
4. Replace the magnetic clutch, and reassemble in
the reverse order.
CAUTION
• After installing the bracket, remove the
original table and loosen the two Allen
screws of the belt drive joint. Move the belt
drive shaft to the magnetic clutch side and
check that the shaft moves smoothly. If it
does not, the shaft is not connected
straight. Loosen the screws securing the
magnetic clutch bracket and adjust its
position.
• The screw on the bracket works as the
turning stopper of the magnetic clutch. Be
sure that the screw catches the magnetic
clutch when installing the bracket.
