Fax

by jdw / August 23, 2004 2:53 AM PDT

I have a Canon Fax 80 faxphone. It was
made in the United Kingdom and therefore
operates on a different frequency than
the United States-made fax machines.

I am trying to find out whether or not
the frequency can be tweaked to allow
this machine to run in the US.

I think I have the US version. I gave that big black box away years ago, but there was some hidden setup keys and menus in the machine. Since I never found a manual, I was barely able to change much about it. But if it is possible, then dig out the manual or maybe google.

BTW, the fax tones are international. I've sent faxes to machines overseas with that model. I can't say the same for dial tone. As such, maybe you can change it from touchtone to rotary dial.

I used it in Italy but still had to hot wire the
phone and the fax wiring both on the machine and
in the wall.

Now, I have a DSL connection so that's out of the
question.

I can actually HEAR the fax in the background when
someone is trying to send a fax or when I try to send
a fax. So, I know it is possible to tweak it.

Exactly how, I still don't know. I called a local
'expert' on fax machines and they emphatically said
'no', the frequencies are different in the two
countries so it can't be done.

Thoughts?

Do you know anything about REN numbers?

What can I write. I've sent faxes overseas to many countries. While dialing tones did vary, faxing is another story.

The new information you noted about DSL is something you shouldn't leave out. The FAX machine may not like being on DSL. The "filter" is required and may cause a fax machine to not work. Even though it should work.

My Canon 80 was years old when I gave it away. So my bet is that yours may be a decade or more old?

Time to move on?

Ringer Equivalence Number

In reply to: Re: Fax

REN = Ringer Equivalence Number. The bare number actually means amperes. The sum of the REN's of all the phones on a single circuit must not exceed the rating of the phone line lest none of the phones ring due to insufficient current available to actuate the ringer mechanism. I have heard 4.0 stated as the MAX per line, but that may be company or line specific.

REN NUmbers

In reply to: Re: Fax

The REN numbers are the posted on every Telephono device such as Phones, FAX machines, FAX modem, PC modem, etc.. It will be labled on the device somewhere, usually the bottom or near the tele chord connection as in REN Or ring equivalence 1.0 or .02..
IT basicly means to measure how much current it takes to triger or ring the device... Older phones and FAX's usually took more to ring.
As I have found out by using one of the new magic Jack phones... Basicly an IP phone that uses broadband connection to make a phone jack... but it lacks ring power to ring my FAX machine because it's REN is 1.0... But it makes calls and sends fax's.. I bought a newer chordless phone with a REN of .08 and it rings fine.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
