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.
