IMPORTANT
•
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
document 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.
•
When cleaning the read area of the platen glass, take care not to damage the white roller
located on the center of the ADF.
