If the printer was unable to send a fax because the receiving fax machine did not answer or was busy, the printer attempts to redial based on the settings for the busy-redial and no-answer-redial options. Use the following procedure to turn the options on or off.
When Busy: If this option is turned on, the printer redials automatically if it receives a busy signal. The factory-set default for this option is Redial.
When No answer: If this option is turned on, the printer redials automatically if the receiving fax machine does not answer. The factory-set default for this option is No Redial.
To set the redial options
From the Home screen on the printer display, press the Up and Down buttons to select Fax, and then press OK.
Select Settings, and then select Auto Redial.
Select the appropriate option, and then press OK.
