2.11.11 Replacing the shutter solenoid
PM cycle: Adjust the solenoid position
every 2,000K.
1. 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.
2. 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. Remove the ADF control board.
3. Remove the harness bracket (2 screws).
4. Remove the solenoid (2 screws) and replace it.
5. Reassemble in the reverse order.
Solenoid position standard
Check the shutter operation by pressing the solenoid
plunger manually. Adjust the solenoid position if
necessary.
When the solenoid is energized, the
shutter tightly shuts the air exit.
When the solenoid is de-energized, the
shutter opens.
NOTE
Because the moving part of the solenoid link is worn
off, adjust the solenoid position every 2,000K
copies. If the shutter is not closed tightly, original
misfeeds may occur.
