Do I need a seperate telephone line for my fax... (by 3 users)

FYI on the fax that will fax out but not receive.
One of the problems I see frequently is that the phone line is plugged into the jack that is for an answering machine or an extension phone. Make sure you have those set.
Also, be sure you have several settings turned OFF.
Many people turn ON Junk Fax, blocking, which will block most of your faxes.
Also check to see if Secure Fax is off and delay fax is off.
Another problem is that a mode called ECM ( Error Correction Mode) is turned OFF, you want ECM turned ON.
Most of the time an issue like this, Receiving not sending or sending not receiving is one of these problems.
Check those things out.
There is a set up menu on all fax machines. Make sure somehow one or more of them were not changed.
Also, you may have a memory clear feature, but be warned that if you do a memory clear, be sure to print out your phone books, and setings list. A memory clear will return the fax to its default setting and resolve many issues.
