Problem

Possible solution

 

 

 

extension phone is off the hook, or if you are using a

 

computer dial-up modem to send e-mail or access the

 

Internet.

 

 

The HP Fax is having problems

Make sure the HP Fax is plugged in. Look at the display

sending and receiving faxes

on the HP Fax. If the display is blank the HP Fax is

 

unplugged. Make sure the power cord is firmly connected

 

to the HP Fax and plugged into a power outlet.

 

After plugging in the power cord, HP recommends you

 

wait five minutes before sending or receiving a fax. The

 

HP Fax cannot send or receive faxes while it is initializing

 

after being plugged in.

 

 

 

• Check to see if another process has caused an error.

 

Check the display for an error message providing

 

information about the problem and how to solve it. If

 

there is an error, the HP Fax 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

 

Send a fax in Error Correction Mode. 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.

 

• If you are using either a private branch exchange

 

(PBX) or an integrated services digital network

 

(ISDN) converter/terminal adapter, make sure the HP

 

Fax 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 HP Fax 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 Fax 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.
