Setting Dial Tone detectionC
When you send a fax automatically, by 
default your machine will wait for a fixed 
amount of time before it starts to dial the 
number. By changing the Dial Tone setting to 
Detection you can make your machine dial 
as soon as it detects a dial tone. This setting 
can save a small amount of time when 
sending a fax to many different numbers. If 
you change the setting and start having 
problems with dialling you should change 
back to the default No Detection setting.

Error and maintenance messagesC
As with any sophisticated office product, errors may occur and consumable items may need to be 
replaced. If this happens, your machine identifies the error or required routine maintenance and 
shows the appropriate message. The most common error and maintenance messages are shown 
below.
You can clear most errors and perform routine maintenance messages by yourself. If you need 
more help, the Brother Solutions Center offers the latest FAQs and troubleshooting tips.
