3) Moisten lint-free paper [1] with 5 to 10
cc of alcohol [2]; then, pour 0.2 to 0.3 g

• Keep the widths of cleaning to
5 to 10 cm in the peripheral
direction of the drum.
• Move the lint-free paper back
and forth 15 to 20 times over a
single area.
Forcing the lint-free paper will
not affect the life of the drum.
5) When the alcohol has evaporated, dry
wipe the surface with lint-free paper. If
the area is uneven, go back to step 4),
and increase the back-and-forth move-
ments.
6) Rotate the drum for the width (5 to 10
cm), and repeat steps 3) through 5) until
the entire area of the surface has been
cleaned.
