HP Photosmart Premium Fax C309 - Manual (Page 154)

NOTE: For information on turning your DSL modem off, contact your DSL provider for support.
Completely remove power for at least 15 minutes, and then turn the DSL modem back on.
Listen to the dial tone again.
• If the dial tone sounds clear (no noise or static), try sending or receiving a fax.
NOTE: You might notice static on the phone line again in the future. If the product stops sending and
receiving faxes, repeat this process.
• If the phone line is still noisy, contact your phone company.
Cause: The product shares the same phone line with a DSL service and the DSL modem might not have been
properly grounded.
If this did not solve the issue, try the next solution.
Solution 12: If you use a PBX or ISDN converter, make sure you are using a port designated for
fax and phone use
Solution: Make sure the product 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 product with a PBX phone system or ISDN line, see the printed
documentation that came with the product.
Cause: You were using either a PBX or an ISDN converter/terminal adapter.
If this did not solve the issue, try the next solution.
Solution 13: Check for and resolve any error messages
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 product will not send or receive a fax until the error condition is
resolved.
You can also check the status of the product by clicking Status in the HP Solution Center.
Cause: Another process caused an error in the product.
If this did not solve the issue, try the next solution.
Solution 14: Lower the fax speed
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
To set the fax speed from the control panel
