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.
This printer has two functions for preventing the mistransmission of faxes. Sending faxes after entering the fax /telephone number twice This function requires you to re-enter the fax/telephone number after entering the number, so that the printer prevents you from misdialing.
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.
