Faxing
The standard wall jack adopted by most countries or regions is RJ11. If the wall jack or equipment in your facility
is not compatible with this type of connection, then use a telephone adapter. An adapter for your country or
region may not come with your printer, and you may need to purchase it separately.
There may be an adapter plug installed in the telephone port of the printer. Do not remove the adapter plug
from the telephone port of the printer if you are connecting to a serial or cascaded telephone system.
