If you have more than one telephone line, then make sure that you enter the number for the line on which the
printer is connected.
What is my dialing prefix?
The dialing prefix is the number or series of numbers that you press before you can dial the actual fax number or
telephone number. If the printer is in an office setting or in a private branch exchange, then this can be a specific
number that you need to press so you can make a call outside the office. This can also be a country code or an area
code that you need to enter if you are sending faxes outside of town. This can be very useful if you frequently send
faxes to the same country or area. When you set the dialing prefix in the utility, the printer automatically inputs the
prefix when you dial the fax number or telephone number.
You can enter up to 8 characters as your dialing prefix. The valid characters are the numbers 0–9, the letters P and W
(uppercase and lowercase), and the characters pound (#) and star (*). If you are using the fax software to enter the
dial prefix, then you may also include the characters minus and comma.
Notes:
•
Some of these characters may not be available, depending on the printer you purchased.
•
Characters may vary depending on whether you are using the printer control panel or the computer keyboard.
When do I need to set Auto Answer to On?
Auto Answer is set to On by default, which lets the printer receive faxes automatically.
If the printer is connected to the same telephone line with an answering machine, then you must set Auto Answer to
On so that you can receive both your voice calls and your faxes. Make sure that the answering machine is set to pick
up on fewer rings than the rings set in the printer. This lets the other devices pick up the voice calls first. If an
incoming call is a fax, the printer can detect fax signals on the line and takes the call.
How many rings should I set?
If the printer is sharing a line with an answering machine, then set the printer to pick up after a greater number of
rings than the answering machine. For example, if the answering machine picks up calls after four rings, then set the
printer to pick up after six rings. This way, the answering machine picks up calls first and your voice calls are
received. If the call is a fax, then the printer detects the fax signal on the line and takes over the call.
If the printer is on a dedicated fax line, then you may set the printer to pick up on any number of rings that you
want.
