Problems with faxing

We unplugged our machine to move it to another phone line. Worked at the other phone line but when we moved it back to the original phone line it no longer faxes. We keep receiving NG/Busy Signal notices.

Before I moved, my Lexmark all-in-one printer worked perfectly, but after I moved, everything worked EXCEPT printing of an incoming fax. Everything sounds the same through the sounds the telephone makes as...

Please go through the following checklist:
  • Make sure to plug the telephone fax line from the phone jack in the wall to the Line port on the back of your printer. For more info, please refer to the Lexmark X125 User's Guide.
  • If you have an answering machine connected to the same fax line, be sure to configure it so that it answers first before the fax machine (e.g. if your answering machine picks up on the 3rd ring, set your fax to pick up on the 6th ring or more)
  • If the line has a voicemail feature, disable it or request for a distinctive ring from your phone company.

You probably have the wrong phone line going to your fax machine. The wire you have going to your fax machine has two lines in it. So when you send a fax it's going out on your voice line. You can go to Radio Shack and get a part that splits the two lines that are in the phone wire so you can select the correct line for your fax machine. the part is

Sounds like a phone line issue.
The phone line isn't a digital line is it? ISDN?
That machine MUST have an analogue line

Can't fax from my HP Laserjet m2727nf.

Check the phone line with a regular phone.

Make sure you are plugged into the LINE port of the fax.

Machine does not answer phone

Some things to check-

I know you said it wasn't unplugged but check the phone line is plugged into the line socket. I don't know how many times I had people who people unknown to them (children, cleaners) have knocked out the line cord and plugged it back in the wrong socket.

Hit the on-hook or hook button and check for dial tone. This will check if the line is still working.

Also the fax will have a mode button. If it has been bumped while moving it could be on manual mode (the machine will not automatically pick up)
