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 mes- sages. 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 the Dial Directories chapter).

If your docu- ment 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 set- tings (see Loading Documents in the Basic Operations chapter). Copy the document on your fax machine to see how it will transmit. The prob- lem may be caused by telephone line interference. Try sending the document again later.

The image received on your fax machine was very poor. Contact the person sending you the fax and ask them to change their Transmit Resolution and Type of Original settings. Ask the person to make a copy of the document on their fax machine to ensure that it is working properly. Then ask them to send the fax again. If you still have a problem, try making a copy of a document on your machine to make sure it is working properly.
