If you are having difficulty with your MFC If you think there is a problem with the way your faxes look, make a copy first. If the copy looks good, the problem is probably not your MFC. Check the chart below and follow the troubleshooting tips. DIFFICULTY Printing or Receiving Faxes Condensed print and horizontal streaks or the top and bottom of sentences are cut off. Poor quality print. Vertical black lines when receiving. Horizontal streaks; lines are missing. Received faxes appear as split or blank pages. Phone Line or Connections Dialing does not work The MFC does not answer when called. Sending Faxes Poor sending quality. Transmission Verification Report says 'RESULT:NG' or 'RESULT:ERROR'. SUGGESTIONS If your copy looks good, you probably had a bad connection, with static or interference on the telephone line. If the copy looks bad, clean the scanner area. If there is still problem, call Brother Customer Service at 1-800-284-4329 (in USA) or 1-877-BROTHER (in Canada). See Improving the print quality on page 12-18. Sometimes you may see vertical streaks/black lines on the faxes you receive. Your MFC's primary corona wire for printing may be dirty, or the sending party's fax scanner may be dirty. Clean your primary corona wire (See Cleaning the drum unit on page 12-27), 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 Customer Service at 1-800-284-4329 (In USA) or 1-877-BROTHER (In Canada). 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. If the received data is divided and printed on two pages or if you get an additional blank page, your Paper Size setting may not be correct for the paper you are using (See Type and size of paper on page 2-1). Make sure that auto reduction function setting is turned on. (See Printing a reduced incoming fax (Auto Reduction) on page 5-5.) Check for a dial tone. Change Tone/Pulse setting. (See Setting Tone and Pulse dialing mode (For Canada only) on page 4-4.) Check all line cord connections. Check power cord connection. Send a manual fax by pressing Hook, or by lifting the external handset and dialing the number. Wait to hear fax receiving tones before pressing Start. Make sure the MFC is in the correct receiving mode for your setup. (See Basic sending operations on page 6-6.) Check for a dial tone. If possible, call your MFC to hear it answer. If there is still no answer, check the telephone line cord connection. If there is no ringing when you call your MFC, ask your telephone company to check the line. Try changing your resolution to Fine or S.Fine. Make a copy to check your MFC's scanner operation. If copy quality is not good, clean the scanner. (See Cleaning the scanner on page 12-25.) 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' or, on the Transmission Verification Report, your MFC may be out of memory. To gain extra memory, you can turn off Fax Storage (See Setting Fax Storage on page 8-3), print fax messages in memory (See Polling on page 5-9) or cancel a Delayed Fax or Polling Job (See Canceling a job while scanning the original on page 6-11). If the problem continues, ask the telephone company to check your phone line. 12 - 13 TROUBLESHOOTING AND ROUTINE MAINTENANCE
