No line signal with SF-5100 Fax

check ring volume

If say you are in a house that has 4 phones in different rooms and you answer a incoming call but its a fax. You can press 9* from your phone and the 5100 will detect it and start to receive (RX) then you can hang up and go to the fax and you should have the received fax. However in practice it hardly ever works. Some of the wiring in houses and offices is just not perfect for this operation to work. try it an see. Have fun. lol

you can try to take out the power hold the red button in and put the power back. if it still do not work. it is the mainboard. or liu

check the on hook button hasnt been accidently pressed as it is looking to hook up to an extension phone exchange line

both the numbers should be same otherwise the fax machine will not work properly ..............you have to ask the person who gave this machine for a change of number

please rate me

I just got a new line just for my SF-5100 fax. It was working before I switched to this phone company. I checked the line on a regular phone and it seemed ok. When I plug it up to my fax machine, when it rings I get this static sound instead of rings. One of my customers said when she tried to fax something, she got that same static sound and it would not go through. When I tried to fax her something, I dialed the number and when the fax machine was repeating the numbers it was a series of that same static sound. Then the operator said I should try my call again - so it did not dial through. A few minutes ago, the screen said RX also. Can you please help?

Make sure you are set for AUTO RECEIVE.

Unplug power cord and re-connect. Do you have a DSL phone line?

What is your question?

The normal problem with a fax that will not receive calls it the phone line.
The Line Voltage, or current may be low, or the signal ( DB loss) may be affecting it.
Let me give you an explaination. When you send, you physically connect to the phone line, make the dial tone and whatever is there, it goes out over the line.
When you receive a fax, it is like a remote control, with a remote you need good batteries to generate enough signal to turn on a product.
With a fax, you require an electrical signal, like a remote control to activate the receive capability. Low power, voltage or current. or static, will not allow it to receive, just like a remote with a bad battery will not turn on a product.
Issues can be. The phone cord between the fax and the jack. A bad jack, something on the outside line.
Using a digital phone line, or having another device on the same phone line drawing down the line, or picking up. A credit card machine, answering machine, even another phone can cause issues. If on a shared phone line, disconnect everthing but the fax and have someone send you a test fax. See if that helps.
But more than 90 percent of fax will send , will not receive issues are phone line related.
