Adjusting the shield screen position
1. Adjust belt tension.
2. Move the slider to the center.
3. Turn the shield motor shaft gear by hand to move
the slider. Let it slide until the front or back slider is
brought in contact with the stopper.
4. Bring the other slider in contact with the stopper
and turn the motor gear further by two teeth of the
belt gear.
5. Tighten the fixing screw.
6. Turn the motor gear by hand again and check that
the shield screen moves smoothly without rolling.
NOTE
• If you detect rolling, repeat this procedure.
Dirt, toner, etc., should not be on the rail.
• To check tension of the shield screen, fully
close the leading and trailing edge of screen,
and lightly press the center with your finger.
Tension is OK if the screen returns easily and
is not slackened when it is released.
7. The stays on the shield unit should fit to the main
body side rails first when the shield unit is
reinstalled.
