Your Line Interface Unit (L.I.U.) is bad. The part # is C9138-60001. Google for part availability.
1 Open or remove the left side door.
2 Remove one screw at the left of the formatter board.
3 Disconnect the flat flexible cable from the connector.
4 Rotate the LIU around the hooks to remove.
It's about a 5 min job. Good Luck.

SOURCE: No dial tone detected
It may be a bad modem on the copier. Plug your phone into the auxillary phone port on the copier and see if you get a dial tone. Also make sure that your cord from the wall is plugged into the line port and not the phone port.

Have you checked with your service provider about sending fax from VOIP lines.
Because iam affraid HP does not support VOIP Services.
Even if you call HP Tech Support they will ask you to call your VOIP Service provider they should have a answer for that.
Because the HP Fax machine only supports Analog signals and the VOIP Services have Digital Siganls which the machine cannot recognise, So please contact your VOIP Services for the same to send send faxes because it is not the fax machine which cannot send fax it is your VOIP Service provider which has a problem.

SOURCE: Fax will not send or receive
You need to contact comcast for this issue and get a seperate phone line to which u need to plug in the allinone. This issue may exist most of the Comcast customers.

Note that if you are sharing a fax line with a phone/dsl line (basically have only 1 wall jack, like me) to make sure you use a phone cord that only has 2 gold connectors (look in the head on either end). Most regular phone cords have 4. If you hook the 6110 up with a 4, the 6110 will say that it is "off the hook".
