Work on the Photosensitive Drum and Cleaning Blade
• Clean the photosensitive drum with a flannel cloth coated with toner. You need not
replace the photosensitive drum if it is free of toner cake and its surface is free of
scratches.
• Clean the cleaning blade with lint-free paper. You need not replace it if its edge is
free of scratches. Thereafter, put lubricant on lint-free paper, and coat the edge of the
cleaning blade evenly with lubricant.
Memo
If the lubricant is not even, the copies may carry white, vertical lines.
• Limit the application to the edge of the blade, i.e., where it will come
into contact with the drum.
• Do not rub the edge with force. Tap lightly over the edge to avoid damage.
• Start from the top to the edge face as if to let the lubricant collect along
the line that will come into contact with the drum.
