Hello,

HP just started a recall on these units due to a potential overheating and fire hazard. They have started a buy back program. Additional details can be found here:

WHat model is the fax machine? Also check to make sure that the phone line and the fax line are not 2 different phone jacks. Also if the phoneline and fax line are on the same jack, make sure to program the fax number into the fax machine. Also, double check if the fax machine has an in and out phone jack that it is in the in jack.

How do i get dial tone on fax machine


first, as a tech, i would make sure your phone jack works, then also make sure the line is plugged into the "line" jack on rear of fax. if those two steps are verified beyond a doubt, press your "hook" button and listen for dail tone. if none, pick up handset and listen. if you get tone on handset, then your speaker is disconnected. if you don't get a tone either way, then chances are you have a bad "NCU" board.

good luck,

Can not get a dial tone. Phone appears to be off the hook. How do I trouble shoot it?


Unplug the phone line from the fax machine. Wait at least 1 minute then call the phone number that goes to the fax machine from another line such as a cell phone. Make sure you get a ring and not a busy signal. If you get a ring then hang up the phone. Plug in the fax machine again and call the fax number again. If you get a busy signal then either your phone if off the hook, the switch that is actuated when the phone is placed in the cradle is bad or your modem in the fax machine itself has gone bad. Another thing to try is unplug the fax machines power cord for 30 seconds then plug it back in. I have seen the modems get "locked up" and keep the phone line open. Unplugging will sometimes reset this and get it working again.
Good Luck and Thank You for using Fixya.

I can not send a fax with samsung scx-4521f


Hi,

do a simple test. press the onhook button to you hear dail tone. try key in your mobile number and see if you got the call.

if all the above is yes there is no issue with the modem.

if you did not hear any dail tone. check your phone line is it working fine.

make sure that your phone line is not hunting line. fax machine does not work with hunting line. only direct line.

Samsung 816 power outage dailing an outside line


First thing you should verify a dial tone on the fax machine. (use any analog phone)
If you have dial tone, press 9 and then a number
Second is it conected through tel. system? (did it have an internal extension) and there is no dial tone then your analog port may be fried. Call your telephone vendor. He should be able to help you.
You can purchase a manual for about 10 dollars
Email your system model number to sales at aaa-avad.com for further instructions
