● 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 printer cannot 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 Send a fax in Error Correction Mode on page 55. 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 cannot fax successfully. ● Make sure the printer 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 printer is connected to the correct port and the terminal adapter is set to the correct switch type for your country/region, if possible. ● If the printer shares the same phone line with a DSL service, the DSL modem might not be grounded correctly. If the DSL modem is not grounded correctly, it can create noise on the phone line. Phone lines with poor sound quality (noise) can cause faxing problems. You can 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 off your DSL modem and completely remove power for at least 15 minutes. Turn the DSL modem back on and listen to the dial tone again. NOTE: You might notice static on the phone line again in the future. If the printer stops sending and receiving faxes, repeat this process. If the phone line is still noisy, contact your telephone company. For information on turning your DSL modem off, contact your DSL provider for support. ● If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord connector that plugs into a telephone wall jack.) Try removing the splitter and connecting the printer directly to the telephone wall jack. The printer cannot receive faxes, but can send faxes ● If you are not using a distinctive ring service, check to make sure that the Distinctive Ring feature on the printer is set to All Rings . For more information, see Change the answer ring pattern for distinctive ring on page 65. ● If Auto Answer is set to Off , you need to receive faxes manually; otherwise, the printer cannot receive the fax. For information on receiving faxes manually, see Receive a fax manually on page 57. ● If you have a voice mail service at the same phone number you use for fax calls, you must receive faxes manually, not automatically. This means that you must be available to respond in person to incoming fax calls. ● If you have a computer dial-up modem on the same phone line with the printer, check to make sure that the software that came with your modem is not set to receive faxes automatically. Modems that are set up to receive faxes automatically take over the phone line to receive all incoming faxes, which prevents the printer from receiving fax calls. 154 Chapter 8 Solve a problem ENWW
