- 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) After the alcohol has evaporated, dry wipe the surface with the lint-free
paper. If the area is uneven, go back to the step 4, and increase the back-
and-forth movements.
6) Rotate the drum for the width (5 to 10 cm), and repeat the step 3 through
5 until the entire area of the surface has been cleaned.
