4. Lower Reading Guide
Note:
This component has the reading glass
and white reference sheet mounted
on it. This component should not be
disassembled unless necessary
because once the component has
been removed, there is a risk of dust
getting inside the reading unit.
When disassembling, be careful with
dusts and do not touch the inner
surface of the glass or the surface of
the lens array.
