information, see Case C: Set up the HP All-in-One with a PBX phone system or an ISDN line.
●If the 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 the HP All-in-One 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 HP All-in-One directly to the telephone wall jack.
