Troubleshooting and Routine Maintenance Sending Faxes Difficulty Cannot send a fax. Suggestions B Check all line cord connections. Make sure the telephone line cord is plugged into the telephone wall jack and the LINE jack of the machine. Transmission Verification Report says 'Result:NG'. Poor fax send quality. Vertical black lines when sending. Make sure that the Fax on page 40.) key is illuminated. (See Entering Fax mode Ask the other party to check that the receiving machine has paper. Print the Transmission Verification Report and check for an error. (See Reports on page 90.) There is probably temporary noise or static on the line. Try sending the fax again. If you send a PC FAX message and get 'Result:NG' on the Transmission Verification Report, your machine may be out of memory. To gain extra memory, you can turn off Memory Receive (see Turning off Memory Receive Operations on page 60), print fax messages in memory (see Printing a fax from the memory on page 55) or cancel a Delayed Fax or Polling Job (see Canceling a fax in progress on page 42). If the problem continues, ask the telephone company to check your telephone line. If you often get transmission errors due to possible interference on the telephone line, try changing the menu setting of Compatibility to Basic(for VoIP). (See Telephone line interference on page 152.) Try changing your resolution to Fine or S.Fine. Make a copy to check your machine's scanner operation. If the copy quality is not good, clean the scanner. (See Cleaning the scanner on page 170.) Black vertical lines on faxes you send are typically caused by dirt or correction fluid on the glass strip. Clean the glass strip. (See Cleaning the scanner on page 170.) Handling Incoming Calls Difficulty The machine 'Hears' a voice as a CNG Tone. Sending a fax call to the machine. Custom features on a single line. Suggestions If Easy Receive is set to On, your machine is more sensitive to sounds. It may mistakenly interpret certain voices or music on the line as a fax machine calling and respond with fax receiving tones. Deactivate the machine by pressing Stop/Exit. Try avoiding this problem by turning Easy Receive off. (See Easy Receive on page 53.) If you answered on an extension telephone, press your Fax Receive Code (the factory setting is l 5 1). If you answer on an external telephone (connected to the EXT jack), press Start to receive the fax. When your machine answers, hang up. If you have Call Waiting, Call Waiting/Caller ID, Voice Mail, an alarm system or other custom feature on a single telephone line with your machine, it may create a problem sending or receiving faxes. For example: If you subscribe to Call Waiting or some other custom service and its signal comes through the line while your machine is sending or receiving a fax, the signal can temporarily interrupt or disrupt the faxes. Brother's ECM feature should help overcome this problem. This condition is related to the telephone system industry and is common to all devices that send and receive information on a single, shared line with custom features. If avoiding a slight interruption is crucial to your business, a separate telephone line with no custom features is recommended. 149
