Your fax machine will not dial. Check the power cable 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 fax machine. If you have an external telephone connected, lift the handset and check for a dial tone. If you do not have an external telephone connected, press the HOOK/V. REQUEST key 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 fax machine may be using the wrong dialling method (pulse or tone) for your area. If you hear changing tones instead of dialling pulses and you know that your area uses pulse dialling, refer to the MF(TONE)/DP(PULSE) dial parameter setting in Programming. If your fax machine is connected to a PBX, make sure you have programmed to work with a PBX (see Connecting to a PBX in Installation).

The display shows a communication error. This alarm indicates any of a number of problems. You may be trying to communicate with an incompatible fax machine (your machine 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 also be out of paper or experiencing a paper jam. Bad telephone line conditions can also cause communication errors. Try sending the fax again and check to make sure you are dialling the correct telephone number. If you have to dial a prefix number to get an outside line, or if you are dialling internationally, you may need to enter a pause (using the PAUSE One Touch key) after the dial prefix or international dialling

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 Dial Directories). Lastly, either your fax machine or the remote fax machine may need servicing. Try sending a fax to another location to check your machine.

If your document had a lot of small type, complex illustrations, photos, or was very light or very dark, try changing your Transmit Resolution and Type of Original settings (see Loading Documents in Basic Operations).
