Oki FAX 5050 - Manual (Page 83)

Problem Solving 71
■ Nothing happens when you press the control panel keys. Open and
close the upper cover.
If that does not solve the problem, turn the OKIFAX off,
wait ten seconds, then turn it on again.
■ The display tells you to replace paper even though there is paper in
the paper tray.
Make sure that the paper is properly stacked in
the tray. Then check for a paper jam in the paper feed path.
■ Your documents jam in the scanner. Check the document for
wrinkles, tears or other damage. If it is damaged, try making a
copy of the document on a photocopier and faxing or
scanning the copy. Make sure there are no staples or paper
clips and that the paper is clean and dry. Make sure the
document is not wider than your OKIFAX can load.
■ Your OKIFAX won’t dial. Check the power cord and wall outlet.
Make sure that your telephone line (not your external
telephone or handset) is connected to the LINE outlet on the
back of your OKIFAX—see page 17. If you have an external
telephone connected, lift the handset and check for a dial tone.
If you do not hear one, there may be a problem with your
telephone line. If you do hear a dial tone, your OKIFAX may
be using the wrong dialing method (pulse or tone) for your
area. If you hear changing tones instead of dialing pulses and
you know that your area uses pulse dialing, refer to the
MF(TONE)/DP(PULSE) dial parameter setting on page 54.
■ The display shows a communication error. A “COMMUN.
ERROR” message indicates any of a number of problems.
• You may be trying to communicate with an incompatible
fax machine (your OKIFAX can only communicate with ITU-
T Group 3 fax machines).
• The remote machine may not be able to perform the
function that you want, such as polling or confidential
messages.
• The remote machine may be out of paper or experiencing a
paper jam.
• Bad telephone line conditions can cause communication
errors. Try sending the fax again and check to make sure you
are dialing the correct telephone number.
• If you have to dial a prefix number to get an outside line, or
if you are dialing internationally, you may need to enter a
pause (using the Pause One Touch key) after the dial prefix or
international dialing code to tell your machine to wait for a
dial tone.
• If you have frequent problems communicating with a
particular remote fax machine, try programming the number
into one of your One Touch keys and then changing the One
Touch Parameters for that One Touch key (see page 28).
• Lastly, either your OKIFAX or the remote fax machine may
need servicing. Try sending a fax to another location to check
your machine.
