I'm not receiving certain faxes. How do I ensure they will all be sent to me?

If you get issues like Faxes can be sent but not received, Faxes can be received but not sent error on your Printer then follow the given troubleshooting steps.
Solution to Faxes can be sent but not received

·Initially, you have to check any of the telephone line services are enabled. There are,
1.Voice Mail
2.Call Waiting
3.Billing Tone
4.Privacy Block
5.Security Screen
6.Anonymous Call Rejection
7.Privacy Manager
·These may block your incoming faxes. So disable the above features.
·If you are using Automatic fax reception option on your fax recipient, then check whether the Automatic Answering feature is enabled or not, if it enables means Auto Answer green LED should be on.
·Check the Ring to Answer value.
·If the value set as answering machine that causes the issue on fax reception. Then change the value to Fax or FaxTel
·Now, you can receive the incoming faxes.
Solution to Faxes can be received but not sent

·Check whether the dialed number is correct or not. Every one of the digits required to make a telephone call from a similar line must be dialed.
·On the off chance that the Speed Dial has been used for dialing or the fax has been sent from your PC, print the page to be faxed and dial the number physically on the HP Fax front board.
·Check whether the Tone Dialing is set on you HP Fax product.
·In the event that faxes are sent effectively from the HP Fax front board, but, it's fail when sent from the PC, test the communication between the HP Officejet 4650 printer and your PC by tapping the Status button in the HP Director application, or attempting to print some record.
·If the printing fails to send the fax, then check whether all cables (from system to HP Officejet 4650 Printer) are connected properly, if it's not then connect it properly.
·Now restart it. On the off chance that communication still can't be set up, Call Printer customer service team via Toll-Free: +1-800-836-3987 to resolve your HP Officejet 4650 fax issues.

Perhaps the Fax (phone) line is dead or disconnected. Can you hear any dial tone?

If not, ring the Telco

when doing the diagnostic testing machine fill up almost full and stop display an ol mode

Sounds rather conflicted...any way, first step "send" a fax to a phone that rings (cell phone, phone near the fax). Make sure that the phone you are calling rings, if not plug a phone in to the fax line and make sure you have a dial tone. If you do try to change the phone line on the fax and repeat. Basicly this step is to ensure the fax is dialing out.

Next, dial the number you are faxing to with your cell phone or another phone. Does the fax machine at the other end answer (squaking noises). If not are you dialing the right number. If the fax machine at the other end does pick up, hang up and wait a few mins (so the line will clear) and try to send your fax again.

Try sending a test fax to a known good (have sent faxes to the number before with success) fax. If this works, its a communication hand shake error. You may need to power cycle both fax machines.

Last Test, plug a different fax machine in were this one is. Using the same phone line and such try to fax again. If this is the only thing that works, the fax machine may have a bad modem.

If further information on testing the modem on the HP fax is needed let me know.

I hope one of these step gives you the help and information you are looking for.

Hi,

HP has a Fax no. to test.

Send any test page as fax on the 1-888-473-2963 and wait till it is send. Once the fax is sent, you will receive a fax as notification ( confirmation ) of the fax being received by HP.

This above no. sometimes is busy so you may need to give couple of tries till you succeed.

Or the best way is to send fax to any of your friend who owns a fax machine and ask them to send fax back to you.

Regards,
Ron

In order to find the solution to this issue, you need the fax number for another fax machine that is operating correctly with which to send and receive faxes. After trying each of the following solutions, try to send or receive a fax from this other fax machine to test if the issue has been resolved with your HP fax product. The other fax can be in the same building, on another telephone line, or at another location with someone who can assist. It can also be helpful to call the person or company that is sending the fax. That party can offer information about how that fax machine behaves when sending a fax. This information can be valuable in determining the nature of the issue.
There are several possible solutions to this issue. Start with the first solution and then continue with the other solutions in the order presented until the issue is resolved. When the issue is resolved, there is no need to continue troubleshooting.
Solution one: Run a fax diagnostic test
Run a fax diagnostic test to make sure that the HP fax product is set up correctly.
Load letter or A4 unused plain white paper into the input tray.
on the product control panel, press the setup button ( ).
Use the down arrow key ( ) to select Tools and then press the OK button ( ).
on the Tools menu, use the down arrow key ( ) to select Run Fax Test and then press the OK button ( ).
Review the results of the test.
If the result of the fax diagnostic test is All Pass ,
Reinitialize the fax
1. With the HP fax product turned on, disconnect the power cord from the back of the HP fax product and from the electrical outlet.
2. Connect one end of the telephone cord to the telephone jack and then connect the other end of the cord to the port labeled 1-Line on the back of the HP fax product.
3. Reconnect the power cord to the back of the HP fax product and then reconnect the power cord to the electrical outlet.
4. After the HP fax product reaches a ready state, try to send and receive a fax again.

If this works GREAT!, if not let me know....JCE

Some basic troubleshooting tips are listed below to help determine the cause.
Check the following items :

1
Ensure the phone cord is plugged directly from the wall jack, into the back port of the fax machine marked "Line", "To Wall Jack", or with a wall jack symbol

2
Remove any other device from the line such as splitters, credit card machines, or telephone answering machines and retry.

3
Turn Error Correction Mode (ECM) off ,
For turning off ECM > press set up > press ok >go to advanced fax set up by using the arrow key > press ok > press arrow key go to OFF > press ok .

After these steps > try to send a fax to undermentioned number , once it is sent u will recieve a confirmatory fax in return as well .

self confirmatory no for fax 1 888 473 2963 .

or u can try to send a fax to a different local number as well.

Thanks

Before you begin


To pinpoint the cause of the issue, please record answers to the following questions:

Can a fax be sent or received?
Can a fax be sent, but not received?
Has the fax function ever worked in the past?

Any error messages may also help to narrow down the cause of the issues.

Print out the following:

- a settings list to view the current fax settings
- a receive log if there are issues receiving faxes
- a send log if there are issues sending faxes
- an activity log if faxes cannot be sent or received.
Initial checks
If the fax option has worked in the past and does not do so now, check that the same connection is being used and that it still works.
Check to see if any configuration settings have been changed that could have affected the fax settings.

Faxes cannot be sent/received:
If you are using a digital line, you need an analog card, an ISDN adapter, or an ADSL filter in order to send faxes.
If a PBX is being used, an ISDN Adapter/ADSL filter will not be used as these are supplied within the system. (A PBX is normally used within a company to share a small number of public lines among a large number of private ones to save on cost.) For instructions on configuring the X6100 Series machine with a PBX, see How and When to Use the PBX Option.
Check the phone line (without the printer):
Test the line by connecting a phone directly into the phone port.
Check for a dialing tone.
If you cannot hear a dialing tone, try another phone cable. Once you can hear a dialing tone, you know that the phone port is live and working.
Make sure the RJ11 cable is not damaged.
Check that the printer is accessing the dialing tone correctly:
Press the Options button on the operator panel five times until ON HOOK DIAL is displayed.
Press Select. You should hear a dialing tone.
If you can't hear a dial tone, make sure that the speaker volume is set to High. (Go to Fax, press Options eight times until SPEAKER VOLUME is displayed, then use the plus or minus buttons to change the setting to HIGH. Press Select.)
If there is still no dial tone, unplug the power cable and the phone lead, then plug them back in and try again.

Faxes can be sent but not received:
Connect the Lexmark All-in-One directly to the phone port. IMPORTANT: Do NOT connect any phones to the EXT port.
Make sure the Fax receive mode is set to answer the fax after 3 rings. (Press the Fax button on the operator panel and then press Options three times until ANSWER FAX WHEN is displayed. Change the settings using the - or + buttons as appropriate.)

Faxes can be received but not sent:
Make sure that Country Code is set correctly:
Press the Fax button on the operator panel and then press Options 15 times until Advanced is displayed.
Press Select.
Press Options 13 times and then press the + or - button until the right country is displayed.
Press Select.

IMPORTANT! These tests must be carried out with NO EXTENSIONS, i.e. phones or answering machines, connected to the EXT port on the All-In-One.

its in the fax preferences option...on the fax icon right click and go to properties..somwhere in the preferences should be an option to select automatically delete sen faxes..or something like that.
