Xerox workcentre 5775 doesn't send or receive faxes

SOURCE: Can receive faxes but are coming through partially or distorted.

Most receive problems relate to phone lines, But yours doesn't.
I would start here.

1. Press the [Menu / Exit] button on the Control Panel. 'System Data' will be displayed on the Display Screen.
2. Press the [Left] or [Right] arrow button until 'Memory Clear' is displayed.
3. Press the [Enter] button.
4. Press the [Left] or [Right] arrow button to select one of the following items to be cleared from memory:
   • System ID: Clears the fax number and name from the machine’s memory.
   • System Data: Restores all options that can be modified to the factory default.
   • PhoneBK / Memory: Clears the speed dial or group dial numbers stored in the machine's memory. In addition, all scheduled job operations that have been reserved are canceled.
   • TX-RX Journal: Clears all records of fax transmissions and receptions.
     
     NOTE: To exit without clearing the item, press the [Menu / Exit] button.
     
     
5. Press the [Enter] button.
6. If necessary, repeat steps 4 and 5 to clear another item from memory.
7. Press the [Stop] button to return to the Standby mode.

At the very least it should send a fax, without doing anything at all, but having it plugged into a phone line. Are you sure the line is good? Does it have a, "on Hook mode" or a button to press to get a dial tone? Otherwise, plug a telephone in and make sure there is a dial tone. Also it could be the cord itself, or has somebody conected it to the wrong jack on the fax machine? These are the things I suggest to check.

You likely need modify darkness or the contrast.

Please take a look at the following from the Xerox site:

Please let me know if this has been helpful or if there is anything else I can do. Thank you.

your toner has nothing to do with sending/receiving faxes. If you can print to the xerox...something is wrong with the software..
delete and re-install software..Xerox website is useless
check the black sensor that dangles into the paper tray. wiggle it up and down, ahten resintalled the tray
