Problems with sending faxes
Problem Cause Solution
Faxes are transmitting very slowly. You might be sending a complex fax, such
as one with many graphics.
Complex faxes take longer to transmit.
The receiving fax machine might have a
slow modem speed.
The fax accessory only sends the fax at the
fastest modem speed the receiving fax
machine can use. Wait for the fax
transmission to complete.
The resolution at which the fax was sent or
is being received is very high. A higher
resolution typically results in better
quality, but also requires a longer
transmission time.
Decrease the resolution and change the
Optimize Text/Picture option.
If there is a poor phone-line connection,
the fax accessory and the receiving fax
machine slow down the transmission to
adjust for errors.
Cancel and resend the fax. Ask the phone
company to check the phone line.
The document might have a gray
background, which can increase fax
transmission time.
Use the Image Adjustment feature to clean
up the background shading.
Faxes quit during sending. The receiving fax machine might be
malfunctioning.
Try sending to another fax machine.
The phone line might not be working. Disconnect the fax accessory from the
phone jack, and connect a phone. Try to
make a phone call to ensure the phone line
is working.
The phone line might be noisy or poor
quality.
Try using a slower fax speed to improve
the reliability of transmission. Use the Fax
Dialing Settings menu to set the fax speed
for sending faxes.
A call-waiting feature might be active. Verify that the fax telephone line does not
have an activated call-waiting feature. A
call-waiting notice can interrupt a fax call
in progress, which causes a communication
error.
The fax accessory is receiving faxes but is
not sending them.
If the fax accessory is on a PBX system, the
PBX system might be generating a dial
tone the fax accessory cannot detect.
Disable the detect-dial-tone setting.
There might be a poor phone connection. Try again later.
The receiving fax machine might be
malfunctioning.
Try sending to another fax machine.
The phone line might not be working. Disconnect the fax accessory from the
phone jack, and connect a phone. Try to
make a phone call to ensure the phone line
is working.
Outgoing fax calls keep dialing. The fax accessory automatically redials a
fax number if the Redial On Busy option is
on or if the Redial On No Answer option is
on.
This is normal operation. If you do not
want the fax to retry, set the Redial On
Busy option to 0, set the Redial On No
Answer option to 0, and set the Redial on
error option to 0.
