(6) Mirror 6
Conducts the reflected light from mirror 5 to the slit.
(7) Slit (glass)
The sub-reflector performs slit functions therefore the slit glass only protects the optical section
from toner dust, etc.
(8) Copy-area indicator unit
This is located inside the original scale. This is for indication of the maximum area in which the copy
can be made at that time.
The indicator is driven by the document motor. The original range is indicated with the copy-area
indicator and orange line on carriage 1.
