Are you able to send faxes when using the printer operator panel - not through Lexmark Productivity Suite application on your computer? Are you able to receive faxes without any problems? Make sure the fax line where the printer is connected is working properly. It could be a signal quality in the connection.
You can also try to decrease the transmission speed when sending faxes. On your printer operator panel:

1. Press the Fax button, then press Options 15 times to get to ADVANCED FAX.
2. Press Select.
3. Press Options ten times until MAX SEND SPEED appears on the LCD display.
4. Change it to 9600 BPS using the - (left arrow) button.

Try to send your fax again.

You will automatically receive faxes from anyone with a compatible fax anywhere in the world. You may be confusing receiving as you had to enter your area code in setup to send faxes. That does not keep you from receiving (or sending) anywhere you like.

Do you have or does the receiving party have a DIGITAL phone line?

ALL fax machines are ANALOG devices.

Lexmark does not allow refilled cartridge on any of their products.

Lexmark, HP and Canon and-many other vendors use proprietary code to protect themselves against the damage of OEM inks.

All companies will void warranties.

Fax machines are ANALOG devices and will not work reliably on DIGITAL phone lines

that means that the fax machine on the other end, can't read your handshake from lexmark. Happens.

www.lexmark.com has the drivers you'll need by model and operating system

Make sure the "Auto Answer " button is On

Make sure ur answering Mech rings are set more than the fax mech...i.e (if ur answering mech is set to 3 then fax mech should be set to 4)....

If u r using DRPD(distingtive ring pattern i.e If u have one line and two numbers.....) then set double ring for fax and single for Phone or answering mech....or vice versa...

You use the same number for fax but you need contact the telephone to provide the fax to same line.You can call LEXmark to set up printer..

As some fax machines are not capable of receiving color faxes, legal size faxes, or faxes at 200x200 dpi resolution, make sure you are sending an A4 or letter size (not legal size) page at standard resolution:
Press the Black button for a black-and-white fax. Press the Quality button to check the selected resolution.
Make sure the All-In-One has enough memory free when you want to save the scanned documents into memory before sending the fax. Please refer to the following document: Click here to link to the relevant document.
Note: The scanned documents will only be saved in the memory before the whole fax is sent if the Scan Before Dial option is turned on. (This is the factory default.) Up to 50 black-and-white fax pages can be stored in memory at standard resolution when there are no pending faxes in the queue.
Turn off the Scan Before Dial option by pressing the following keys on the operator panel:
Press the Fax button, then press Options 15 times to get to ADVANCED FAX mode.
Press Select.
Press Options nine times until SCAN BEFORE DIAL appears on the LCD display.
Change the setting from Yes to No using the + (right arrow) button.
Press Select.
Note: The Scan Before Dial option controls whether a document is scanned before a call is dialed. This parameter only applies to a mono fax that uses either 200x100 or 200x200 resolution. Higher resolution mono faxes and all color faxes are scanned after the call is dialed and the receiving machine's capabilities are known.
Lower the fax transmission speed to 14400 or even 9600 bps, as some older fax machines are not capable of receiving a fax at a high speed. To do so:
Press the Fax button, then press Options 15 times to get to ADVANCED FAX.
Press Select.
Press Options 10 times until MAX SEND SPEED appears on the LCD display.
Change it to 9600 BPS using the - (left arrow) button.
Press Select.
Turn off ECM (Error Correction Mode) by pressing the following keys on the operator panel:
Press the Fax button, then press Options 15 times to get to ADVANCED FAX.
Press Select.
Press Options 11 times until ERROR CORRECTION appears on the LCD display.
Change the setting from On to Off using the + (right arrow) button.
Press Select.
Note: Turning off this option makes it possible to receive a fax when the receiver fax machine does not support certain error correction modes. The X6100 Series only supports 1-D MH encoding with the error correction. Fax transmissions without ECM and other ECM types can result in bad quality on the received page.
