L75 vs DSL phone line

My L75 quit working when I switch my phone line to a digital one through internet.
Then I hooked it to another line that carries my DSL. It started working intermittently and when it does, it’s extremely slow. I wonder if it’s a compatibility issue or the machine itself became damaged after hooking it with the digital line first time.

Fax machines are ANALOG devices designed to work with POTS (plain old telephone system).

Sometimes you can get away with a fax or two w/digital lines, but the machine will be very unreliable.

I don't think there is any damage as the machines have voltage limiter circuits built in. [except for lightning]

POOR LINE CONDITION


Do you have DSL internet coming into the location where you are attempting to use the FAX machine? The reason I ask is because, if that is true, you may have a filter to reduce noise and that may be causing problems. I have DSL and whenever I use my FAX machine I have to unplug the filter from the phone wall receptacle and plug the fax line straight into the wall phone receptacle. Here is a photo of what
you may find if you have DSL.

Ng poor line condition/ out of memory


Generally this is an indication that the telephone line you are trying to fax over has either alot of noise on it or possibly on the receivers end.If you are on a telephone line which has DSL service on it make sure you have a line filtre connected on the fax to eliminate line noise for your DSL modem, as well if you are using a digital phone service such as Vonage or your Cable providers phone service this is a digital service, contact brother technical support to have your modem speed lowered to 9600bps through the firmware switches on your machine.

I have a Cannon MX310 printer, fax , copier. I cannot receive faxes. Can it have something to do with the fact that I have digital phone service, what setting does it need to work.


You might try a DSL phone filter to eliminate extraneous noise on the digital line. My digital phone line had constant, repetitave clicking noise until I installed a DSL filter. Have you tried calling your fax number from a cell phone to see if there is noise on the line and or if the fax will pick up?

I've changed my internet providers and have gone from a cable internet svc to a dsl phone line provider. Now my computer fax machine says it is offline. Is there a setting that I need to change?


Most likely cause is you don't have a dsl filter on your fax line. Without the filter, your fax machine's modem can't discern between a dsl signal and a telephone signal Since the telephone line coming into the building is now carrying a dsl signal, a filter is necessary to receive/send faxes.

I can't hook up the way it says to


Fax machines need an RJ-11 phone cord and are ANALOG

DSL uses RJ-45 and is DIGITAL.

Don't waste your money on a DSL filter, they won't work reliably.

HISSS on line; no dial-tone; no fax in or out


it sounds like you may not have any dial tone. the hiss [white noise] you are hearing is from the dsl modem.try plugging a regular corded phone into the jack to check for dial tone.if there is none,call your phone company.also try plugging the fax machine into another jack where you know there is dial tone.
good luck

 Must have DSL filter attached before fax, not sure how you are saying you have it setup, but phone line should come from wall then to filter then to fax socket marked line, phone should be hooked to socket on fax marked EXT, if you dont have dedicated fax line then fax number will be same as phone no.

 

If you have Adsl then there will be a lead from wall that splits into two, one goes to your modem (ADSL) and the other marke phone or line needs to go to fax socket marked LINE
