If phone line conditions are less than perfect, transmission (send) and reception (receive) problems can occur. Decrease the reception (RX or receive) speed if frequent fax transaction error messages appear on the LCD.
Sending Documents If an error occurs during sending, the fax beeps intermittently for a few seconds and an error message appears on the LCD. If this happens, correct the problem and then press <Stop>, then try sending the document again.

The LCD will display [RECEIVED IN MEMORY] and a message showing the problem. See below the error messages , their cause and the action you need to take to correct the problem.
