78 Problem Solving
Problem Checklist
Your OKIFAX is a complex machine with many
features and functions. Many problems you experience
may be due to improper programming. If you are
experiencing a problem, read through the following list
of problems and solutions before calling your
Authorized OKIFAX Dealer for service.
■ The display is blank. Make sure your OKIFAX is turned on.
Check the power cord to make sure that it is securely
plugged into the OKIFAX and into the wall outlet. Check
your wall outlet to make sure that it has power.
■ 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
61.
■ The display shows a communication error. A “COMMUN.
ERROR” message indicates any of a number of prob-
lems.
• You may be trying to communicate with an incompat-
ible 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 experi-
encing a paper jam.
• Bad telephone line conditions can cause communica-
tion 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
