Solution:

•Make sure the HP All-in-One is connected to the port that is designated for fax and phone use. Also, make sure that the terminal adapter is set to the correct switch type for your country/region, if possible.

NOTE: Some ISDN systems allow you to configure the ports for specific phone equipment. For example, you might have assigned one port for telephone and Group 3 fax and another port for multiple purposes. If you have problems when connected to the fax/phone port of your ISDN converter, try using the port designated for multiple purposes; it might be labeled "multi- combi" or something similar.

For more information on how to set up the HP All-in-One with a PBX phone system or ISDN line, see the printed documentation that came with the HP All-in-One.

•Try setting the Fax Speed to Medium (14400) or Slow (9600).

For more information, see:

“Set the fax speed” on page 30

Cause: The Fax Speed setting is set too fast.

Solution: You might need to send and receive faxes at a slower rate. Try setting the Fax Speed to Medium (14400) or Slow (9600) if you use one of the following:

•An Internet phone service

•A PBX system

•Fax over Internet Protocol (FoIP)

•An ISDN service

For more information, see:

“Set the fax speed” on page 30

Cause: The HP All-in-One might be connected to a telephone wall jack that is set up for digital phones.

Solution: Make sure you connect the HP All-in-One to an analog phone line or you will not be able to send or receive faxes. To check if your phone line is digital, connect a regular analog phone to the line and listen for a dial tone. If you do not hear a normal sounding dial tone, it might be a phone line set up for digital phones. Connect the HP All-in-One to an analog phone line and try sending or receiving a fax.

Cause: The HP All-in-One shares the same phone line with a DSL service and the DSL modem might not be properly grounded.

Solution: 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.
