NOTE
(1) Photoconductive Drum (large green cylinder) right above the Guide Film.
You need to replace the Drum if damaged, as it is a very important part in creating the
print image.
Be careful about the following matters.
a.) Do not touch the drum.
If you put your fingermark or oil on the Drum, it will cause for the defective image.
b.) Take off such metal accessories as watch or ring.
You will have to replace the Drum if you damage the Drum scratching with such
accessories.
c.) Do not leave the Upper Unit open for more than 10 minutes as the Drum is very
sensitive to light. (Direct sunlight is very harmful.)
(2) Do not use water, organic solvent and alcohol for the cleaning.
4. Close the Engine Unit.
