Reinstallation Procedure
1. Align the CCD Unit with the center of the graduations as illustrated on the left and then tighten the
four screws.
4025D116AA
2. Reinstall the Original Glass.
3. Turn ON the Power Switch.
4. Carry out the adjustment procedure for CD-Mag. (see D-67). If the specifications are
not met, loosen the CCD Unit mounting screws and move the CCD Unit in the FD direction as necessary.
NOTE
• Hold the CCD Unit by hand when moving it. NEVER use a screwdriver or similar tool to
tap to move it, as a varied distance between the CCD sensor and lens results.
<Adjustment Procedure>
• If the specified width on the copy is less than the specifications, move the CCD Unit to
the left.
• If the specified width on the copy is longer than the specifications, move the CCD Unit to
the right.
✽
Moving the CCD Unit over 1 mm results in the zoom ratio being varied about 2%.
