How to receive fax

It's probably set to manual receive and the ringer volume is low or off.

if this is to every line then you have a bad main board or your ringer waiting period needs to be increased... (meaning the amount of times it rings before pickup...

Quoted from the manual: The HP all-in-one will not automatically answer calls. You must receive all faxes manually by pressing Start Fax Black or Start Fax Color. For information on receiving faxes manually, see Receive a fax manually. You might use this setting if the majority of calls on this phone line are voice calls and you rarely receive faxes.

Should be in the operators manual. You need to change the setting, through the control panel, to "autoanswer". You can print out the current settings by pressing the "menu" button, scrolling to "user settings" and print from there. You can also select the number of rings before the machine picks up, and the volume of the ringer.

First, make sure the phone line to the fax is plugged into the LINE socket, NOT THE PHONE socket on the machine. Next, try calling your fax machine from a cell phone to see if the fax answers. If no answer, you may have to go into FAX SETTINGS or FAX SETUP from the Lexmark menu. You may have to change any or all of the following: RINGER SETTINGS, AUTO RECEIVE, RECEIVE MODE, TONE/PULSE DIALING, OVERSEAS MODE, ETC. Trial and error getting the Lexmark to answer calls from the cell is probably the easiest way. BEFORE YOU START, print out or write down each setting you may change. This way, if it does not work, you can go back to the original setting.

After months of trying to solve this problem I finally figured out that the machine was set to phone/fax mode instead of fax only. If you have a dedicated fax line you can set to FAX ONLY MODE. In FAX ONLY MODE you can control whether or not the machine rings when it receives a fax call. You do this by selecting Data Registration, Press Set and use the up and down arrows to select 4. RX Settings. Press Set and use the up and down arrows to display the item you want to set or change and turn the ringer OFF. Press Set.

Try setting the receive mode to FAX/ANS. If you want the fax not to pickup before a phone call comes in, you should set the number of fax rings to a higher number, like "5" for instance. Set the answering machine rings less and the fax higher. The machine will usually record a message first and then detect a fax tone.

RINGER IS SET TO SILENT MODE,PLEASE CHANGE IT HAPPY FAXING OMNIPRESENT

If it does do the following (taken from the manual) Receiving automatically in FAX mode 1. Press Rcv.Mode/Contrast until the display shows ?FAX MODE?. 2. When you get a call, the machine answers the call on a specified number of rings and receives a fax automatically. You can change the number of rings. See ?RINGS TO ANSWER? on page 5.4. To adjust the ringer volume, see ?Adjusting volume? on page 2.8. If the phone is not ringing, then the call is never even getting to your fax machine.
