SUGGESTIONS Make sure the machine is in the correct receiving mode for your setup. (See Basic receiving operations on page 5-1.) 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 machine's scanner operation. 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 machine 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 Printing a fax from the memory on page 5-5) or cancel a Delayed Fax or Polling Job (See Canceling a scheduled job on page 6-11). If the problem continues, ask the telephone company to check your phone line. If the copy you made shows the same problem, your scanner is dirty. (See Cleaning the scanner on page 13-18.) If your machine is set to Easy Receive ON, it is more sensitive to sounds. Your MFC 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 Easy Receive to OFF. (See Easy Receive on page 5-4.) If you answered at the machine, press Black Start and hang up immediately. If you answered on an extension phone, press your Fax Receive Code (default setting is ( 51). When your MFC answers, hang up. If you have Call Waiting, Call Waiting/Caller ID, Ring Master, Voice Mail, an alarm system or any other custom feature on a single phone line with your machine, it may create a problem sending or receiving fax data. For example: If you are sending or receiving a fax message while a custom feature signal comes through on the line, the signal can temporarily interrupt or disrupt the fax data. 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 data on a single, shared line with custom features. If avoiding a slight interruption is crucial to your business, we recommend a separate phone line with no custom features. Clean the print head. (See Cleaning the print head on page 13-11.) If you clean the print heads five times and the print has not improved, call Brother Customer Service at 1-800-284-4329 (in USA), 1-877-BROTHER (in Canada) or (514) 685-6464 (in Montreal). Make sure the Brother TWAIN driver is selected as the primary source. In PaperPort, click Scan in the File menu and select the Brother TWAIN driver. TROUBLESHOOTING AND ROUTINE MAINTENANCE 13 - 9
