Receiving Problems
Cannot receive a fax automatically.
Q Is the machine set to receive automatically?
A For the machine to receive faxes automatically, the receive mode must be set to <FaxOnly>, <Fax/
Tel>, or <AnsMode>. (See Chapter 5, "Receiving Faxes.") If you have set <AnsMode>, confirm that
an answering machine is connected to the machine and that it is turned on with an outgoing
message properly recorded.
If you set <MAN/AUTO SWITCH> to <ON> in <FAX SETTINGS> of the Menu, the machine will
receive faxes automatically even when the receive mode is set to <Manual>. (See <4. MAN/AUTO
SWITCH> of "Menu Descriptions," on p. 8-6.)
Q Is the machine's memory full?
A Wait for the machine to finish any fax or print jobs stored in the memory. Then ask the other party to
resend the fax.
Q Did an error occur during reception?
A Print an ACTIVITY REPORT and check for an error. (See "Printing the ACTIVITY REPORT," on p.
6-2.) You can also check the RX REPORT when it is printed automatically. (See "Adjusting the RX
REPORT Setting," on p. 6-5.)
Q Is the telephone line connected properly?
A Make sure all line connections are secure. (See "Connect telephone cable," in the Set-Up Sheet.)
The machine does not switch automatically between telephone and fax receptions.
Q Is the machine set to switch automatically between telephone and fax receptions?
A For the machine to switch automatically, the receive mode must be set to <AnsMode>. (See Chapter
5, "Receiving Faxes.")
Confirm that an answering machine is connected to the machine and that it is turned on with an
outgoing message properly recorded.
Q Is the sending fax machine able to send the CNG signal that tells the machine that the incoming
signal is a fax?
A Some fax machines cannot send the CNG signal that tells the machine the incoming call is a fax.
In such cases, you will have to receive the fax manually. (See "Receiving Faxes Manually: Manual
Mode," on p. 5-4.)
