■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.
