Problems with receiving faxes
Problem Cause Solution
Incoming fax calls are not being
answered by the fax accessory (no fax
detected). The rings-to-answer setting might not be
set correctly. Check the rings-to-answer setting.
The fax cable might not be connected
correctly, or the fax cable is not
working. Check the installation. Make sure you
are using the fax cable that came with
the product or with the fax accessory.
The phone line might not be working. 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.
If you are using a PBX system, the ring
signals might not be configured
correctly. Check the ring-signal configuration on
the PBX system.
A voice-messaging service might be
interfering with incoming faxes. Do one of the following:
● 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.
Faxes are being received very slowly. You might be receiving a complex fax,
such as one with many graphics. Complex faxes take longer to transmit.
The sending fax machine might have a
slow modem speed. 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.
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. Ask the sender to decrease the resolution
and resend the fax.
If there is a poor phone-line connection,
the fax accessory and the sending fax
machine slow down the transmission to
adjust for errors. Ask the sender to resend the fax. Ask the
phone company to check the phone line.
Faxes are not printing on the product. No paper is in the input tray. Load paper. Any faxes received while
the input tray is empty are stored and
will print after the tray has paper.
The Fax Printing Schedule feature is in
use.
Faxes print according to the schedule.
To print faxes immediately, disable the
Fax Printing Schedule feature.
