Fax troubleshooting checklist
If you encounter problems sending and receiving faxes, then check the connection first:
1
Check for a dial tone on the telephone line by plugging an analog telephone into the wall jack, DSL filter, VoIP
device, or cable modem where you connected the printer. Make sure you plug the telephone into the same port.
If you do not hear a dial tone, then contact your line provider.
2
While the printer is connected to the telephone line, check for a dial tone by plugging an analog telephone into
the
port of the printer.
If you do not hear a dial tone, then use the checklist below. Listen for a dial tone after checking each item.
If you hear a dial tone but still have problems sending and receiving faxes, then see the other topics in this section.
Connection checklist
•
Make sure that the printer and other devices on the line (if applicable) are set up and configured correctly
according to your setup scenario.
•
Make sure that the cables are connected to the correct ports.
•
Make sure that the cables are securely plugged in.
Check the cable connections for the following hardware, if applicable:
Power supply
Answering machine
Cable modem
Splitter
Telephone
VoIP adapter
DSL filter
RJ-11 adapter
•
If the printer is connected to a Digital Subscriber Line, then make sure you are using a DSL filter for the printer.
•
If the printer is connected to a VoIP adapter or cable modem, then make sure that the printer is plugged into the
first phone port.
•
If you are using a splitter, then make sure that you are using a phone splitter. Do
not

IN
THE
PRINTER
If you did not enter your user information during initial setup, then enter your fax name and fax number. In some
countries, you cannot send a fax without entering your fax name or company name. Some fax machines also block

send and receive faxes. It is not necessary, however, to set the modem to its fastest transmission capability. The
speed of the modem of the receiving fax machine must match or be greater than the speed at which you are
sending your fax. Otherwise, your fax will not be received.
