1.4 OPTICS
1. When installing the exposure glass, make sure that the red mark on the
edge of the glass faces up. This side has received a special treatment to
be smoother and generate less static electricity. This is especially
important when the ARDF is installed.
2. When moving the 1st or 2nd scanners, always hold them at the center.
Move them slowly, carefully, and gently.
Abrupt movement may cause the belt to slip into the wrong position on
the scanner drive pulleys.
3. Do not bend or crease the exposure lamp flat cable. Be careful of this
especially when reinstalling the lens housing cover.
4. When reinstalling the lens housing cover, make sure that the light
shielding mylar on the original length sensor does not interfere with the
light path to the ADS sensor board.
5. Do not touch the following parts with bare hands:
a) Reflectors
b) Exposure lamp
c) Mirrors and lens
d) ID sensor and V
L
patterns
6. To clean the mirrors and lens, only use a clean soft cloth damped with
alcohol or water.
7. Do not adjust uneven exposure by changing the exposure lamp position
but by using the exposure adjusting plates. Adjusting the lamp position is
very difficult because the filament cannot be seen clearly as the lamp is
frosted.
8. Adjust the exposure lamp voltage (SP48) only when the drum initial
setting (SP66) is performed.
9. Do not remove the lens housing guide plate and the 3rd scanner guide
plate. They were positioned on the optics base plate with a special jig at
the factory.
