Cause
The rings-to-answer setting might not be
set correctly.
The fax cable might not be connected
correctly, or the fax cable is not
working.
The phone line might not be working.
If you are using a PBX system, the ring
signals might not be configured
correctly.
A voice-messaging service might be
interfering with incoming faxes.
You might be receiving a complex fax,
such as one with many graphics.
The sending fax machine might have a
slow modem speed.
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.
If there is a poor phone-line connection,
the fax accessory and the sending fax
machine slow down the transmission to
adjust for errors.
No paper is in the input tray.
The Fax Printing Schedule feature is in
use.
Solution
Check the rings-to-answer setting.
Check the installation. Make sure you
are using the fax cable that came with
the product or with the fax accessory.
Disconnect the fax accessory from the
phone jack, and then connect a phone.
Try to make a phone call to ensure the
phone line is working.
Check the ring-signal configuration on
the PBX system.
Do one of the following:
Discontinue the messaging service.
●
Use a phone line dedicated to fax
●
calls.
Decrease the rings-to-answer for the
●
fax accessory to a number less than
the rings-to-answer for the voice
mail.
Complex faxes take longer to transmit.
The fax accessory only receives the fax
at the fastest modem speed the sending
fax machine can use. Wait for the fax
transmission to complete.
Ask the sender to decrease the resolution
and resend the fax.
Ask the sender to resend the fax. Ask the
phone company to check the phone line.
Load paper. Any faxes received while
the input tray is empty are stored and
will print after the tray has paper.
Faxes print according to the schedule.
To print faxes immediately, disable the
Fax Printing Schedule feature.
