line that can interfere with the HP All-in-One, preventing the HP All-in-One from sending and receiving faxes. The DSL filter removes the digital signal and allows the HP All-in-One to communicate properly with the phone line. To check if you already have a filter installed, listen to your phone line or dial tone. If you hear noise or static on the line, you probably do not have a DSL filter installed, or it is installed incorrectly. Obtain a DSL filter from your DSL provider. If you already have a DSL filter, make sure it is connected correctly.
Cause Another process has caused an error in the HP All-in-One.
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.
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 (14400) or Slow (9600).
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
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. You can check the
