■ Cleaning the Read Area of the Platen Glass
(Only for the PC-D340/FAX-L400 Models)
Black lines may appear in copies when the ADF is used to feed documents.
This is caused by paste, ink, correction fluid, or other foreign matters in the read area of the platen glass (shaded
area). Use a clean soft cloth to wipe the read area clean. Take particular care to clean at the locations where the
black lines are appearing on copies.
If you have trouble getting the glass clean, wipe with a cloth moistened with water or a mild neutral detergent,
and then wipe the glass dry with another cloth.
• Paste, ink, correction fluid, and other foreign matter can soil the platen glass when you send a
document through the ADF while the paste, ink, or correction fluid on the original is still wet. This is
what causes black lines on copies. Whenever you load a document in the ADF, always check to make
sure that any paste, ink, or correction fluid that is on the document is completely dry.
