Difficulty with Operation If you think there is a problem with the machine, make a copy first. If the copy looks good, the problem is probably not the machine. Check the table below and follow the troubleshooting tips. DIFFICULTY SUGGESTIONS Printing and Receiving Faxes Condensed print and horizontal streaks/top and bottom of sentences are cut off. This can be caused by static or interference on the telephone line. You can make a copy using the Copy function and see if the same problem occurs. If the copy is also bad, call your Brother dealer for service. Vertical streaks/black lines Sometimes you may see vertical streaks/black lines on the faxes you appear on the fax you receive receive. Either the machine's primary corona wire for printing may be dirty, or the sending party's fax scanner may be dirty. Clean your primary corona wire, or ask the sender to make a copy to see if the problem is with the sending machine. Try receiving from another fax machine. If the problem continues, call Brother dealer for service. Machine "hears" voice as CNG tone If the machine is set to Fax Detect (with an External Telephone) ON, it is more sensitive to sounds. The machine may mistakenly interpret certain voices or music on the line as a calling fax machine and respond with fax receiving tones. Deactivate the fax by pressing Stop/Exit. Try avoiding this problem by turning Fax Detect (with an External Telephone) to OFF. (See Fax Detect (with an External or Extension Telephone), page 29.) Horizontal streaks You may get a fax with horizontal streaks or with missing lines. Usually this is caused by a poor telephone connection. Ask the other party to send the fax again. Phone Line or Connections Dialling does not work Check for a dial tone. Change TONE/PULSE setting. (See Setting the Dialling Mode (Tone/Pulse), page 20.) Check all line cord connections. Check power cord connection. Send a manual fax by lifting the external telephone's handset, and dialling the number. Wait to hear fax receiving tones before pressing Fax Start. The machine does not answer Make sure the machine is in the correct receiving mode for your when called setup (either Fax, Fax/Tel (F/T) or TAD). Check for dial tone. If possible, call the machine to hear it answer. If there is still no answer, check the telephone line cord connection. If there is no ringing when you call the machine, call your Telephone Company to check the line. No dial tone on the external telephone's handset Lifting the external phone's handset. If you hear no dial tone, check telephone line cord connections at the machine and wall socket. Check that the external telephone is connected to the machine correctly. Test the wall socket with another single line telephone. If no dial tone on the wall outlet, call your Telephone Company. MAINTENANCE Troubleshooting and Maintenance 135
