that carries phone accessories. You will also need another phone cord, which can be a standard phone cord that you might already have in your home or office.

•Try connecting a working phone and phone cord to the telephone wall jack that you are using for the device and check for a dial tone. If you do not hear a dial tone, call your local telephone company for service.

•Other equipment, which uses the same phone line as the device, might be in use. For example, you cannot use the device for faxing if an extension phone is off the hook, or if you are using a computer dial-up modem to send an e-mail or access the Internet.

•Check to see if another process has caused an error. Check the display or your computer for an error message providing information about the problem and how to solve it. If there is an error, the device will not send or receive a fax until the error condition is resolved.

•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.

For information about changing ECM, see the onscreen Help. If the problem persists, contact your telephone company.

•If you are using a digital subscriber line (DSL) service, make sure that you have a DSL filter connected or you will not be able to fax successfully. For more information, see Case B: Set up the device with DSL.

•If you are using a DSL service and have connected a DSL filter, the filter might be blocking the fax tones. Try removing the filter and connecting the device directly to the wall.

•Make sure the device is not connected to a telephone wall jack that is set up for digital phones. 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.

•If you are using either a private branch exchange (PBX) or an integrated services digital network (ISDN) converter/terminal adapter, make sure the device is connected to the correct port and the terminal adapter is set to the correct switch type for your country/region, if possible. For more information, see Case C: Set up the device with a PBX phone system or an ISDN line.
