SOURCE: HP LaserJet 3330MFP quit recieving & sending faxes

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.

SOURCE: HP 5610xi All-in-one wont send fax since switching from Vonage to Comcast

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.

Good Luck

SOURCE: my hp officejet v40xi says off hook when I try to

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".

Cant send or recieve fax


Might be silly question but is it setup to auto transmit and receive? And have you tried to operate it manually? + take out the inline filter fax machines operate on volume'db' to soft and it can't hear, to loud and it can distort sound.

I cant receive fax


Is there a dial tone if you pick up the reciever ? Can you send faxes or use the machine to make a phone call ? If you can make calls or send faxes the machine probably needs to be set to the auto recieve mode so that it automatically answers when a fax is being recieved. If no dial tone you may have a loose connection to your phone jack.

HP 7680 Fax paper will not go through


Have you checked that you can get a dial tone?
Can you recieve fax's?.
If no dial tone then check that you have the telephone cord plugged into the line jack on the back of the fax machine and not the tel or ext sockets.May be a telstra problem so plug another phone into the wall socket to see if you can dial out.
Also make sure that the fax is set to pulse dialing.

HP 5610 All-in-one can recieve faxes but not send, when sending a fax i always get the busy tone. connot understand why, recieves faxes prefectly.


Have you set for the proper dialing? there's a choice for pulse or tone dialing, you probably need tone dialing. Also the number needs to be put in just as you would dial on a phone.

Cant send a fax


Confirm dialing the correct fax number?

Any 0s to get an outside line, any special area codes?

What happens when you try to send a fax, can you hear a dial tone? can you hear the fax ringing? can you hear a response from the recipiant?

Fail to send and recieve


Well it was fixed after I called our telephonecompany.
They told us last Thursday that the lina was ok, but yesterday I talked to a extremely competent callcenteragent and he could confirm the problem lay in the connection.
So, it wasn't a problem wit the JX200 after all.

Fax machine won't send or recieve faxes


press the "on hook" dial key. this should let you hear a dial tone. If you don't hear a dial tone, then it is probably the phone line and not the machine. You may have to call your telephone company.

Sending a fax


First make sure that the fax button has been pushed and is llit...

The 2820 should have a handset. In order to use manual transmission (when you get to hear all the beeps and whistles) you will need to load the document then pick up the handset. then dial the number, when you hear the recieving fax tone then hit the start button.

The 2820 should also have a hook hold button pressing this will allow you to hear the dial tone and the numbers you dial along with the receiving fax tone. If you dont hear anything when you press this button then you may want to use the volume buttons to increase the volume.

Also remember that if you have not picked up the handset or pressed he hook/hold button the unit will use automatic mode, which is to say that all you will do is load the document, dial the number, and then press the start button.

Recieving faxes
  • Plug a regular, non-digital, phone into the fax's phone line and see if you get a dial tone
    • If you do not have a dial tone, seek support from your telephone service provider
  • Dial the fax number from a phone    
    • Normal circumstance is that you will have the fax machine pick up and make high-pitched noises
    • If the fax does not pick up, put a regular phone on the fax line and see if the regular phone rings when dialed
      • If the phone rings, answer it and see if there is line noise
        • If the line is clear, call the service number listed on your fax
        • If the line is staticy or unclear, call your telephone service provider
      • If the phone does not ring, call your telephone service provider
Sending faxes
  • Attempt to dial the fax number you are trying to send to from another phone.
    • If you hear electronic noises on the line, the other end has a fax machine on the other end
      • Check to see if you can recieve faxes.
    • If the remote fax does not answer, the problem is on the remote side, contact the recipient
