Question about HP 640 Inkjet Fax Machine

1 Answer

HP 640 fax

About 2 days ago my fax stopped working. I checked the power. Reattached all the cables. Tried another device (it worked fine.) Unplugged everything and waited 10 minutes and re-plugged but nothing has worked. The display is accurate but there is no dial tone and makes no noise when dialing. Is it dead or is there another way to reset it?
The machine is less than 9 months old with very light use.

MY LEXMARK X125 STOPPED RECIEVING AND SENDING FAXES. IT HAS ITS OWN LINE NOT CONNECTED TO COMPUTER. ALSO MY SPEAKER DIAL TONE IS NOT WORKING. WHEN CHECKING MY DRPD WONT SET UP EITHER. THIS JUST HAPPENED 2...


Hello. If everything else is working, printing and copying, unplug the printer from the power source. Check the telephone line from your phone company by unplugging the fax machine from the wall jack where it is connected to. Plug a telephone device straight to that wall jack and check for a dial tone. If there's no dial tone, contact your phone company. If there is, plug the fax machine back to that wall jack. You can also try replacing the telephone cable with a another known working cable. Plug the printer back to the power source. Check again. Hope this helps.

HP 640 fax won't send fax but phone works


Unfortunately wer purchased two new hp office jet 7610 which do not come with cabling and we could not get the fax to work. I spent 3 days on the telephone with hp and British Telecom each of which blamed it on each other. After doing some research on the internet I discovered that hp require a strange cable formant which is called a 'cross-over cable' is required. I bought them from cabling4less.co.uk and the product code is BT-203X. They can be found on their web site www.cabling4less.co.uk The link is: http://www.cabling4less.co.uk/category.php?cat_id=237 This should resolve this frustrating problem.

Won't send faxes to 817 area code, all others OK


The recipient may have a DSL phone line, or receiving to a fax server that blocks your area code.
