Re: We can't send or received faxes

Just a suggestion. This effect can happen if you have plugged the line cord into the tel jack instead of line jack.

After dialing and scanning to send fax the machine says wait and then goes to print report and starts printing

Pl. check the tel.line, test for voice communication,if its ok and without any noise, there may be problem with fax communication line(internal), this may be tested by connecting a parallel telephone set and hearing the beep tones while sending the fax.(put the document in the ADF dial any one no. just to cut dial tone press START, ) If no beep tones in regular interval heard. its due to LIU card fault(mostly). You need to replace or repair the card.

Problem: Busy/No Response on all outgoing faxes

Put the document you want to send into the transmit tray, pick up the handset, listen for a dial tone, and then dial the # on the keypad..
It should ring just like any other phone. When the machine on the other end picks up and you hear the tones, press the start button.
Anything other than fax tones on the other end, it is not your faxes fault.

Can't receive faxes, I can send faxes and print reports though. messages says "Receiving Error - ask sender to send again". Any ideas?

Have you gotten and old telephone and plug it in where the fax goes and see (hear) if you have any problems with a good dial tone and phone line? Does your phone line go near any high power a/c units big motors, mite think about a ferrite core for the fax/phone line. hav ATT or other carrier check your line. Also check your own line when ATT does it there check is only to the location not inside the house. Does your sure protector protect your phone line, really good sureg protectors protect Power lines fax lines!!! and in some case network lines

The machine seems to work ok, except when putting in a fax document, inputting the #, and pressing fax start, it pulls the document through, then just beeps every 2 seconds. It then does put out a...

The number that you are sending to is either busy, disconnected, or off the hook. To chek BEFORE dialing press the "HOOK" button (located to the left of the "1" key) and listen to the transmission this will help you in your troubleshooting. If you don't hear a dial tone BEFORE dialing, then the trouble is on your end.
A fast-paced busy signal could indicate a "downed" telephne line.
Finally, sometimes the line that you are sending to has so much stuff hooked up to it (56K dialup fax, multiple phones, alarm system dialer, credit card validator, teenage daughter) that you may be better off e-mailing instead.

I can receive faxes but cannot send them

Check your fax speed settings, also, make sure you get a good clear dial tone on the line. Sometimes it wont send if it detects line noise.

The 2820 should have a handset. In order to use manual transmission (when you get to hear all the beeps and whistles) you will need to load the document then pick up the handset. then dial the number, when you hear the recieving fax tone then hit the start button.

The 2820 should also have a hook hold button pressing this will allow you to hear the dial tone and the numbers you dial along with the receiving fax tone. If you dont hear anything when you press this button then you may want to use the volume buttons to increase the volume.

Also remember that if you have not picked up the handset or pressed he hook/hold button the unit will use automatic mode, which is to say that all you will do is load the document, dial the number, and then press the start button.

Sending and receiving problems

Where the telephone line comes in from the wall, make sure that it is plugged in the "line" or "wall" port. There is probably another port call "tel" or "acc". If the line is plugged into that port you will still get a dial tone but you are not connected to the fax's modem. You hope that's it. Ed
