Checks
Are there scratches in the
peripheral direction of the
photosensitive drum?
When paper wraps around the
transfer drum, is it in contact with
the transfer cleaning brush,
polishing roller, or the like?
Clean the standard white plate,
scanning lamp, reflecting plate, and
mirror. Is the problem corrected?
• Be sure to adjust the CCD if you have replaced the scanning lamp, mirror,
CCD, or any other optical part.
When Using Cleaner Lubricant
Before detaching the cap, shake the cleaner lubricant bottle well. Be sure to
apply the lubricant evenly along the cleaning blade. If uneven, its lubricating
ingredients can slip under the cleaning blade, adhere to the photosensitive drum,
and cause vertical white lines in copy images.
If such a problem is noted,
1) Make 10 solid black copies in Bk mono color.
• This step alone may correct the problem.
2) Remove the photosensitive drum, and coat a flannel cloth with black toner;
then, wipe the surface of the drum, and then mount the photosensitive drum.
• This step will remove the lubricating ingredient adhering to the surface of
the photosensitive drum.
