Advanced receiving operations
Operation from extension telephones
If you answer a fax call on an extension telephone, or an external
telephone in the EXT. jack of the machine, you can make your
machine take the call by using the Fax Receive Code. When you
press the Fax Receive Code
51 , the machine starts to receive a
fax. (See Easy Receive on page 4-6.)
If the machine answers a voice call and pseudo/double-rings for you
to take over, use the Telephone Answer Code
#51 to take the call at
an extension phone. (See Setting the F/T Ring Time (Fax/Tel mode
only) on page 4-5.)
If you answer a call and no one is on the line, you should assume that
you’re receiving a manual fax.
■
Press 51 and wait for the chirp or until the machine’s LCD
displays Receiving, and then hang up.
Your caller will have to press Start to send the fax.
For Fax/Tel mode when power key is On
When the machine is in Fax/Tel mode, it will use the F/T Ring Time
(pseudo/double-ringing) to alert you to pick up a voice call.
If you're at the machine, you can lift the handset or press
Speaker Phone to answer. If you’re at an extension phone, you’ll
need to lift the handset during the F/T Ring Time and then press #51
between the pseudo/double rings. If no one is on the line, or if
someone wants to send you a fax, send the call back to the machine
by pressing
51 .
Fax/Tel mode when power key is Off
You can change the default setting of the On/Off key to
Fax Receive:On so that you can receive faxes when the power
key is off. (See On/Off Setting on page 1-5.) Fax/Tel mode will work
in the following ways.
When the machine is in Fax/Tel mode and pseudo/double-rings to
alert you to pick up a voice call, you can only answer by picking up
the machine’s handset.
If you answer before the machine answers with pseudo/double-ringing,
you can pick up the call at an external or extension phone.
