Check
If the waveform has irregular patches, the lens, mirror, exposure glass, white pres-
sure plate, or CCD may be dirty.
If the waveform level is lower at the ends than in the middle, the fluorescent lamps
may be wearing out.
If the waveform has sharp peaks or dropouts, the CCD may be defective.

Access the SBU as explained in “Preparation” above.
Set the oscilloscope scale to 0.2 V/unit (vertical) and 0.5 ms/unit (horizontal).
Connect the oscilloscope probe to XVIDEO and the ground to GND.
Light the fluorescent lamps (see
page 2-33).
Place the 200 dpi test pattern on the
exposure glass.
Loosen the Iens securing screw [A]
(Allen screw).
Move the lens block back [B] and
forth until B is maximized (see the
diagram opposite). B/A must be
more than 0.45 in the center and
more than 0.3 at each end of the
waveform.
Tighten the lens securing screw.
