HP Officejet 6600 e-All-in-One Printer - H711a H711g - Manual (Page 112)

• 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.
