Question about Lexmark X9350 All-In-One InkJet Printer

1 Answer

Fax dial tone

I cannot fax with my x9350. I get a dial tone for only one second or less, then it disappears. I had the same issue yesterday and discussed with lexmark online chat support and was advised to get a new printer that mine must be defective. I did that today only to experience the same exact issue. I can fax on the same line with the same cable with a HP fax all in one machine. Brand new printer yesterday – second brand new printer today. Any idea why i cannot keep a dial tone?

Re: fax dial tone

Sure...check the line, with a you have call waiting or something like that enabled..that can cause some issues, with the tone interruption to the internal modem.

Fax problem

I want to make sure I understand this completely. You get no dial tone from the fax machine when hooked up to VOIP. In the past, was there an audible dial tone from the fax, or did it just dial silently and give you an error if there was no tone? When you said you got a dial tone by connecting a phone to the ext phone port of "the machine" did you mean the fax machine? If you get a dial tone by running a phone through the fax machine, then the line is good. I have used a fax machine over Sunrocket before they went defunct, which used the same technology base as Vonage - so it should work. If you used to get an audible dial tone when using the fax, and no longer do, and you are geting a dial tone on a regular phone that is connected to the ext. port of the fax machine, then the problem has to be in the fax machine itself, not the VOIP. If you can verify that, we can go from there.

No dial tone. Can not fax or receive faxes. Tried several phone lines and wires.

two things to check first, make sure the phone cord goes into the unit where it says line and not ext. The second thing to check, plug a regular phone using the same cord and see if you have a dial tone, maybe you really dont. if you need to dial an ext. # first to get a dial tone, you need to program that in.

if all that does not solve the problem, you mostly like have a bad fax board in the unit.

None of our faxes are going out and we receive error number 87

set the fax so you can hear dial tone... if no dial tone then check the fax line.... if fax line plugged in... plug it out of the fax and plug into a phone... if still no dial tone then change fax cable... if dial tone... then call your cell... if static... fax wont work call phone company... if you get a funny signal call phone company...

We have a HP colour laser jet CM2320nf MFP and when we try and send a fax it comes up with error report Comm Error 345. Please explain

Check phone line. use a normal phone and plug into the same phone wall socket that the MFP is using, do we have a dial tone? Do we have a noisy line, any buzz or crackel will cause issues

If there is no dial tone ring line supplier, If it is noisy line do the same

Also check phone line is plug into "line" socket in the back of machine not "ext'

Also check no prefix is required to dial out, unit needs its own phone line..

Also try using resolution of fax as standard not fine, this requires less info to go threw the line

In Australia we have a thing called folds (fax online diag service), basicly it is a fax number you ring and the phone company who own the line send back a report, most times the issue is noisy line or no line available

hope this helps

I must tell you that this is not a printer issue, since printer does not have inbuilt fax capabilities....Actually you are trying to send fax from the computer using a Data Fax Modem. Printer just used for scanning and printing documents for fax...

1. Please check if your computer have Fax modem.
Look at the back of the system tower, if you see a phone jack port (probably two of them).

2. If yes then , you need to have a telephone cable directly from wall (not the ethernet cable coming from DSL modem), fax works on analog signals which is possible only from telehone line.

If your phone line is working, there is no chance the it will give you error again for NO Dial tone

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.

Dial tone in fax mode

Is the phone wire from the wall jack plugged into the slot in the back of the machine marked "line" and not "phone"?
