Receiving faxes
Q: My fax never answers. What s wrong?
A: Check to make sure your fax machine is properly connected to a working
AC
power
outlet and phone jack (see page 1.7). If you re using a second phone with your
machine, make sure i ts connected properly (page 2.20).
Q: Sometimes when I answer my machine with the optional handset, I hear a beeping
sound that repeats every few seconds. Is this a fax?
A: Yes. When you hear these fax tones, someone is trying to send you a fax. Next
time, press
START
and hang up the handset. Your fax will receive the message.
Q: Does my fax machine have to be plugged in to the
AC
power jack to receive a mes-
sage?
A: Yes. Y our phone will ring if the phone line is connected, but you can t receive a fax
unless your fax machine is plugged into both the phone jack and the
AC
power jack.
Make sure your fax machine is always plugged in so you never miss an important
fax message.
Q: Can I receive a fax if I m using the phone on my machine?
A: You can receive a fax from the person to whom you re talking. When that person
has a document ready in his/her machine s feeder, press
START
.
W orking with your answering machine
Q: People have complained that they call my fax machine and hear my answering
machine s message, but are cut off before they can send a fax. What happened?
A: Any remote fax machine attempting to send a fax must hear responding fax tones
within 40 seconds after the person at that machine presses the st art key. That 40
seconds includes getting the dial tone, dialing the number, listening to the p ause
before the ringing starts and the remote fax machine answering the ring. Only af ter
that time does your message play.
That s why we urge you to create a short outgoing message. The shorter the wait -
ing period, the more likely it is that the remote fax machine will proceed with the
transmission. Please create an outgoing message on your answering machine
that s no longer than 10 seconds (see page 2.1 1 for a suggestion).
Polling
Q: What s the purpose of polling?
A: Polling let s you automatically pull a document which is set in another fax
machine. You can poll whenever you need to retrieve information and don t want
the source to pay for the phone call. W ith polling, you pay for the call and get the
information you need.
How your fax machine works
How a fax machine works is simple:
You put a p age into your fax machine s feeder and call a fax number . Your machine
makes a satisfactory connection with the other machine, and then
Your machine t akes the document.
An image scanner in your fax machine examines the information on the page.
Your machine wraps the document.
Your fax machine translates the scanned information into a numeric code and com -
presses the code for the fastest possible transmission speed.
Your machine sends the document.
Finally, your fax machine sends the compressed code.
On the other end of the line
The remote fax machine receives the code.
Your machine unwrap s the document.
The remote fax machine uncompresses and deciphers the code, turning it into a rep-
resentation of the scan your machine made.
The remote fax machine prints the representation.
The only difference between a regular telephone call and a fax call is the content of the
transmission:
On a regular call, your telephone sends your voice.
On a fax call, your fax machine sends a coded image.
The way fax machines work is regulated closely by the International Telecommunications
Union (
ITU
), an agency of the United Nations. The st andards the
ITU
applies ensure the
compatibility of your fax machine with millions of other machines worldwide. However,
they also limit the way you can use your machine with other devices, such as tele-
phones and answering machines.
