• Make sure you have correctly connected the HP Fax to the

and when receiving

equipment and services that share the phone line with your

faxes.

HP Fax.

(continued)

Use the 1-LINE port on the back of the HP Fax to connect to the

 

wall jack, and use the 2-EXT port to connect any other equipment,

 

such as a PC modem or an answering machine. For more

 

information and connection diagrams, see fax setup on page 75.

 

• Using a telephone line splitter can cause faxing problems. (A

 

splitter is two-cord connector that plugs into a wall jack.) Try

 

removing the splitter and connecting the HP Fax directly to the

 

telephone wall jack.

 

• Check that the telephone wall jack has a working telephone line by

 

plugging in a phone and checking for a dial tone.

 

• Telephone lines with poor sound quality (noise) can cause faxing

 

problems. Check the sound quality of the telephone line by

 

plugging a phone into the wall jack and listening for static or other

 

noise. If you hear noise, turn off the Error Correction Mode (ECM)

 

feature on your HP Fax and try faxing again. For information, see

 

use error correction mode on page 46. Also contact your phone

 

company to report the noise problem on your line.

 

• Other equipment using the same telephone line as the HP Fax

 

might be in use. For example, you cannot use your HP Fax for

 

faxing if an extension phone is off-hook, or if you are using your

 

PC modem to e-mail or access the Internet.

 

• If you are using a digital subscriber line (DSL), make sure that you

 

have a DSL filter connected or you will not be able to fax

 

successfully. Obtain a DSL filter from your DSL provider. The DSL

 

filter removes the digital signal that blocks your HP Fax from

 

communicating properly with the telephone line.

 

For information on how to connect the DSL filter, see faxing from a

 

DSL line on page 76.

 

• Check for error messages on the front panel display of your

 

HP Fax. Until a product error condition is resolved, you will not be

 

able to send or receive faxes.

 

• If you are using either a PBX or an ISDN converter, make sure the

 

HP Fax is connected to the port that is designated for fax and

 

phone use.

 

Note that some ISDN systems allow you to configure the ports for

 

specific phone equipment—for example, you might have assigned

 

one for telephone and Group 3 fax and another for multiple

 

purposes. If you continue to have problems when connected to the

 

fax/phone port, try using the port designated for multiple purposes

 

(might be labeled “multi-combi” or something similar).
