Question about Xerox PRINTERS - FAXCENTRE 2121 21PPM LSR 250 SHT TRAY SHTFDR All-In-One Laser

2 Answers

Faxcentre 2121 This fax machine will send faxes, but won't receive them. It's connected to a standard analog voice line. I tried an analog phone, called the number, and it works, but if I try and fax to it, it just rings and rings and doesn't pick up. Is there a setting I have to change on the menus?

Yes, there are settings in the menu. Scroll to the set up mode.
In there you can find fax recieve. Choose the setting for for auto answer mode, then select the amount of rings. Once you have this, try it again and see if it answers.
If it does not answer this might be a hardware issue, call Xerox for repair.

You do have your phone number and ID set into memory I assume. That is a must.
Check an see if Junk Fax is turned off. It will reject 99 percent of calls.
Make sure ECM is ON.
Be sure you are not set to ans/fax mode.
Turn off secure receive, and manual receive.
Make certain you are plugged into the " LINE" jack and not "EXT".
After eryfying those things. Then you most likely have a phone line issue. Let me explaine this. It will make more sense after i do.
When you send a fax, you manually turn on the phone line. You energise a relay, just as picking up a phone and actuating the switches in the phone to connect to the line, you physically make the connection.
There are 3 conditions that must me met to connect an incomming / received fax.
1 is line voltage, 2 is line current and 3 is decibel loss.
When you are receiving a call, the connection to accept a fax is based on signal strength. If any of those 3 above are not correct, there will not be a strong enough signal to make the fax board pick up. You may have a bad jack or the phone line from the the jack to the phone may be bad.
a good example, and very accurate, it like using your TV/VCR?DVD remote control with weak batteries. Press change channel, volume or on and off, most of the time it won't work. You could take a volt meter and measure the battery, and you would measure 1.5 volts. But the battery being weak can't give enough current, or wattage, and the channel won't change, the volume will not adjust and it will not turn on and off. But walk up to it and press the buttons and wala, it works.
Check those settings I have suggested first. Then I very very very much suspect a phone line issue, even if it faxes out, and has a dial tone.

Cant receive faxes. constant busy signal when dialing in.

Hi Janet
Try using a standard phone to call your Fax Line
Connect a phone to this Line to test for voice
Disconnect Fax Machine from Phone Line
Reset Fax machine
The Fax machine is supposed to respond to the right tones being sent down the voice line
If it is not responding & all else works then check your Fax settings for "Receiving"

Can't send or receive faxes

it's most likely the compression on the phone line or you need to set up your fax machine for proper receive mode.
Contact your phone service provider to see if they support faxes.
(Faxes cannot handle nearly as much compression as standard voice)

Will not receive faxes

Are you sure your phone line was not somehow moved into the ext or phone jack and not plugged into the LINE jack? That is the most common reason that happens.
If thats not the case, I would replace the phone cord, then have my phone line checked. Rarely if you can send and not receive is the machine a problem.
There are several conditions that have to exist to receive a fax. Receive is unlike send. When you send, you physically make a connection when you press the send button.
Receive is an electrical signal that tells the machine to turn on. The best way I can describe why it is a phone like issue is this. The phone line must have the right voltage, current and gain to make the connection, if the line is faulty, think of trying to change a channel or adjusting you TV volume with a remote that has weak batteries. You press and press and maybe it will change and maybe not. Same principle with a phone line that is weak. it may or may not conenct.
But first, check where its plugged into the machine and change the cord from the machine to the wall jack.

Cannot send faxes when using cable company's digital voice modem

Sending faxes

You can hook a fax to any standard phone line. That is what they are designed for. The only issue is if you share the fax with your telephone, you will need to set the machine up to receive the fax before you answer the phone.

Invalid number

Fax machines do not work well or at all on digital lines. They are designed for analog lines, like the standard phone company line. You may have to install a dedicated fax line from your tel. company.

Brother Intellifax 770 fax machine failure to receive faxes

I get calls all the time about fax issues. I work for Comcast and have guided people to the right answers about third party devices. We use a digital connection. Analog is a dying medium. Most calls are concerning HP and Brother but I know others fax machines have had problems too. The new HP machines have a digital setting. HP is aware of digital issues and can help you. It is unfortunate that old fax machines are not digital but a new fax is inexpensive if you wish to buy one. Analog takes up too much space. An example: Six digital television channels can fit in the same space (bandwidth) as one analog. That is why the FCC mandated the change. The same goes for phone lines. I Google almost every problem concerning fax machines and if you go past all the upset comments you will get to the comments that offer remedy. I also wanted everyone to know that a second, no frills fax line from Comcast is very inexpensive and our way of offering a dedicated fax line intead of a distinctive ring fax option.
