The printer is having problems sending and receiving faxes • Make sure you use the phone cord or adapter that came with the printer. (If you do not use this phone cord or adapter, the display might always show Phone Off Hook.) • Other equipment that uses the same phone line as the printer might be in use. Make sure extension phones (phones on the same phone line, but not connected to the printer) or other equipment is not in use or off the hook. For example, you cannot use the printer for faxing if an extension phone is off the hook or if you are using a computer dial-up modem to send e-mail or access the Internet. • If you are using a phone splitter, the splitter could cause faxing problems. Try connecting the printer directly to the telephone wall jack. • Make sure that one end of the phone cord is connected to the telephone wall jack, while the other end to port labeled "1-LINE" on the back of the printer. • Try connecting a working phone directly to the telephone wall jack and check for a dial tone. If you do not hear a dial tone, contact your telephone company to check the line. • Make sure you connect the printer to an analog phone line, or you cannot send or receive faxes. To check if your phone line is digital, connect a regular analog phone to the line and listen for a dial tone. If you do not hear a normal-sounding dial tone, it might be a phone line set up for digital phones. Connect the printer to an analog phone line and try sending or receiving a fax. • The phone line connection might be noisy. Phone lines with poor sound quality (noise) can cause faxing problems. Check the sound quality of the phone line by plugging a phone into the telephone wall jack and listening for static or other noise. If you hear noise, turn Error Correction Mode (ECM) off and try faxing again. • If you are using a DSL/ADSL service, make sure that you have a DSL/ADSL filter connected. Without the filter, you cannot fax successfully. • If you are using either a private branch exchange (PBX) or an integrated services digital network (ISDN) converter/terminal adapter, make sure the printer is connected to the correct port and the terminal adapter is set to the correct switch type for your country/region. • You are using a Fax over IP service. Try to use a slower connection speed. If this does not work, contact your Fax over IP service's support department. 26 Solve setup problems
