If dark bands/black streaks appear on copies, follow the procedure below to clean the fiber lens.If the problem persists after cleaning the fiber lens, then replace the cartridge.
Top side
Turn the power switch OFF and unplug the copier.
Align the platen with the 1mark by sliding it to the left.
Clean the top side of the fiber lens. To clean, run a cotton swab (not included) over the entire length of the lens several times.
Reverse side
Open the top cover and remove the cartridge.
Clean the reverse side of the fiber lens. To clean, run a cotton swab lightly over the entire length of the lens several times.
Once the cleaning is complete, replace the cartridge, close the top cover and slide the platen back into the center position.
When cleaning the fiber lens, be sure to use the flat type of cotton swab that is normally used for cleaning audio equipment. A round cotton swab will not fit into the groove properly.
Do not soak the cotton swabs in any type of cleaning solution or alcohol before using them to clean the fiber lens. Only use dry cotton swabs.
If the above procedure fails to remedy the copy image problems, contact your dealer or service representative.
