Solution: Check the display or your computer for an error message providing
information about the problem and how to solve it. If there is an error, the HP All-in-
One will not send or receive a fax until the error condition is resolved.
You can also check the status of the HP All-in-One by clicking Status in the
HP Solution Center.
For more information on error messages, see
Errors.
Cause: You are using either a PBX or an ISDN converter/terminal adapter.
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.
• Try setting the Fax Speed to Medium or Slow.
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 or Slow if you use one of the following:
• An Internet phone service
• A PBX system
• Fax over Internet Protocol (FoIP)
• An ISDN service

1. Press Setup.
2. Press 5, and then press 7.
This selects Advanced Fax Setup and then selects Fax Speed.
