Caution on Using the Cleaner Lubricant
You must shake the container well before removing its cap. When applying to
the cleaning blade, be sure the application is uniform; uneven application will
allow the lubricating ingredients to slide over the cleaning blade and adhere to
the photosensitive drum, causing vertical white lines on the copies.
If such a problem is noted,
1) Using the color for which vertical white streaks are noted, make 10
solid copies in continuous mode.
• This step may correct the problem.
2) Remove the photosensitive drum, and using a cloth coated with the
color in question, wipe the surface of the drum; then, install the photo
sensitive drum.
• Remove the lubricant adhering to the photosensitive drum as indi cated.
