Printing Received Faxes
Difficulty Suggestions
 Condensed print
 Horizontal streaks
 Top and bottom sentences are 
cut off
 Missing lines
This is usually caused by a poor telephone connection. Make a copy; if your copy 
looks good, you probably had a bad connection with static or interference on the 
telephone line. Ask the other party to send the fax again.
Vertical black lines when receiving. The sender's scanner may be dirty. Ask the sender to make a copy to see if the 
problem is with the sending machine. Try receiving from another fax machine.
Left and right margins are cut off or 
a single page is printed on two 
pages.
If the received faxes are divided and printed on two pages or if you get an extra 
blank page, your paper size setting may not be correct for the paper you are using.
(See Set Paper Size and Type on page 13.)
Turn on Auto Reduction.
(See Online User’s Guide: Shrink Page Size of an Oversized Incoming Fax.)
Telephone Line or Connections
Difficulty Suggestions
Dialing does not work. 
(No dial tone)
Check all line cord connections. Make sure the telephone line cord is plugged into 
the telephone wall jack and the LINE jack inside the machine.
(Canada only) Change the Tone/Pulse setting.
(See Online User’s Guide: Set Tone or Pulse Dialing Mode.)
Send a manual fax by pressing Hook and dialing the number. Wait to hear 
fax-receiving tones before pressing Fax Start.
If there is no dial tone, connect a known-working telephone and telephone line 
cord to the jack. Then lift the external telephone's handset and listen for a dial tone. 
If there is still no dial tone, ask your telephone company to check the line and/or 
wall jack.
If you subscribe to DSL, VoIP, or MagicJack services, contact your service 
provider for connection instructions.
The machine does not answer 
when called.
Make sure the machine is in the correct Receive Mode for your setup. 
(See How to choose the correct Receive Mode on page 29.) Check for a dial tone. 
If possible, call your machine to hear it answer. If there is still no answer, check 
that the telephone line cord is plugged into the telephone wall jack and the LINE 
jack inside the machine. If there is no ringing when you call your machine, ask your 
telephone company to check the line.
