WARNING
■ This machine must be grounded using a three-prong plug.
■ Since the machine is grounded through the power outlet, you can protect yourself from
potentially hazardous electrical conditions on the telephone line by keeping the power
to your machine on when you connect it to a telephone line. When you want to move
your machine, protect yourself by disconnecting the telephone line first, and then the
power cord.
■ Lightning and power surges can damage this product! We recommend that you use a
quality surge protection device on the AC power line as well as on the telephone line,
or unplug the lines during a lightning storm.
Special Line Considerations
Roll Over Phone Lines
A roll over phone system is a group of two or more separate telephone lines that pass
incoming calls to each other if they are busy. The calls are usually passed down or
“rolled over” to the next available phone line in a preset order.
Your FAX/MFC can work in a roll over system as long as it is the last number in the
sequence, so the call cannot roll away. Do not put the FAX/MFC on any of the other
numbers; when the other lines are busy and a second fax call is received, the fax call
is transferred to a line that does not have a fax machine. Your FAX/MFC will work
best on a dedicated line.
Two-Line Phone System
A two-line phone system is nothing more than two separate phone numbers on the
same wall outlet. The two phone numbers can be on separate jacks (RJ11) or combined
into one jack (RJ14). Your machine must be plugged into an RJ11 jack. RJ11 and RJ14
jacks may be equal in size and appearance and both may contain four wires (black, red,
green, yellow). To test the type of jack, plug in a two-line phone and see if it can access
both lines. If it can, you must separate the line for your machine.
