If you experience vertical lines when copying or scanning from the ADF (Auto Document Feeder), or if you send a fax using the ADF and the recipient experiences vertical lines, cleaning the ADF glass may resolve this issue.
Note If the sender sends a document that is larger than Letter-size or Legal-size, such as 11 x 17 inches, the sender's device may send the fax automatically reduced in size or divided, or send only a part of the original. Make sure that the printer is turned on.
