7.2 Cylindrical lens cleaning
The SDP-Eco 1630 III incorporates a
highly accurate optical system in
which the lens is positioned
extremely close to the exposed
surface.
Therefore, if the lens is soiled with
dirt or dust due to environmental
conditions, for example, it may show
up as a vertical line (white or black).
1) If a vertical line appears, open the
front door, loosen the two screws on
the cylindrical lens unit, and remove
the entire unit by gently pulling it out
toward the operator.
2) Inspect the lens under a bright
fluorescent light to check its
cleanliness and, if there is any dirt or
dust, clean it off with a blower.
Do not use compressed
air when cleaning the
lens.
3) Never touch the lens with your hand
or any kind of tool. These lens can
be easily scratched and may require
replacement.
The plate will be fogged
after you replace the
lens. Before the next
operation, feed one
sheet through the
machine.
4) Re-assemble the cylindrical lens unit,
reversing the previous procedure. Be
sure to firmly re-insert the unit as far
back as it will go into the machine
chassis.
