telephone and Group 3 fax and another port for multiple purposes. If you continue to have problems when connected to the fax/phone port, try using the port designated for multiple purposes; it might be labeled "multi-combi" or something similar. For information on setting up your HP all-in-one with a PBX phone system or ISDN line, see Fax setup.
●If your HP all-in-one shares the same phone line with a DSL service, the DSL modem might not be properly grounded. If the DSL modem is not properly grounded, 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 your HP all-in-one stops sending and receiving faxes, repeat this process.
If the phone line is still noisy or for more information on turning your DSL modem off, contact your DSL provider for support. You can also contact your telephone company.
●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 HP all-in-one directly to the telephone wall jack.
The HP all-in-one is having problems sending a manual fax
Solution
●Make sure the telephone you use to initiate the fax call is connected directly to the HP all-in-one. To send a fax manually, the telephone must be connected directly to the port labeled "2-EXT" on the HP all-in-one, as shown below. For information on sending faxes manually, see Send a fax manually from a phone.
