Your machine is connected to a PBX and you can not dial out.

You must enter your dial prefix before the telephone number for each number that you dial or program into your machine. Also, your machine must be programmed for PBX operation before it will work. See “Connecting to a PB X” in the Setting Basic Features chapter.

You want to answer an external telephone but your machine always answers first.

If you are using an external telephone, change your machine’s ring response user function setting. See the “Customizing Features and Operations” section.

Your received faxes sometimes look distorted.

If the document received is wider or longer than the paper you have loaded into your paper tray, your machine automatically reduces the length of the document to fit on your paper. Or, you may have to set the width reduction function to on. This type of problem could also be communication related, or the document may have jammed during scanning. If the document is unreadable, ask the sender to fax the document again.
