Cannot Receive Faxes Automatically
Machine Does Not Switch Automatically Between Voice And
Fax Calls
Quality Of Received Fax Is Poor

Cause
Action
The receive mode displayed on the
bottom left of the LCD is not
<
FaxTel
>, <
FaxOnly
>,
<
DRPD
>, or <
AnsMode
>.
If <Manual> is displayed, you cannot receive faxes unless you pick
up the handset and either press [Color] or [Black], or dial the remote
receiving ID.
If you want to receive faxes automatically, which means not having
to do anything when you are sent a fax, set the receive mode to
<
FAX/TEL AUTO SW
>, <
FAX ONLY MODE
>, <
DRPD
>, or
<
ANS.MACHINE MODE
> (see page 107). If set to
<
ANS.MACHINE MODE
>, connect an answering machine to the
machine (see page 82) and check that a message plays when the
answering machine answers.
Cause
Action
The receive mode displayed on the
bottom left of the LCD is not
<
FaxTel
>, <
DRPD
>, or
<
AnsMode
>.
There will be no automatic switching between voice and fax calls
unless the receive mode is set to <
FAX/TEL AUTO SW
>, <
DRPD
>,
or <
ANS.MACHINE MODE
>. If set to <
ANS.MACHINE MODE
>,
connect an answering machine to the machine (see page 82) and
check that a message plays when the answering machine answers.
The sender’s fax machine is unable
to send a CNG signal (the signal
which indicates that the call is a fax
call).
Some fax machines are not able to send CNG signals. If so, receive
the fax manually. (See page 107)
Cause

OFF
>.
Set <
ECM RX
> to <
ON
>. (See page 155)
The sender’s fax machine is dirty. The image quality of the fax is mainly determined by the sender’s fax
machine. Contact the sender and check whether the scanning area of
his/her fax machine is dirty.
Cause
Action
<
ECM RX
> is set to <
OFF
>.
Set <
ECM RX
> to <
ON

The sender’s fax machine is not
ECM-compatible.
If the sender’s fax machine is not ECM-compatible, the fax will be
received in the standard mode without error correction.
