Fax send failure to ONE fax destination (Most Common)

 

Step Action Additional Assistance
  1

First check the more obvious reasons why a fax might fail to send to a recipient. 

  1. Correct fax number
  2. Proper entry of the fax number on the numeric keypad
  3. If using a fax shortcut to initiate the fax, verify the number was entered properly during fax shortcut creation.
  4. Proper dialing prefix; e.g., 9, 99, 991, 1...
  5. Proper country calling code.

 

  • The MFP's User's Guide.
  • This is found on  the original driver's CD, or it can be downloaded from Lexmark.com.

Attempt to resend the document.

If successful, consider the following to prevent future send failures.

  • Increase the number of redial attempts. (Automatic Redial)
  • Increase the amount of time between redial attempts. (Redial Frequency)
  • Reduce Max Send Speed if the problem continues.

Reducing send speed may be required if the recipients fax machine is connected to a digital phone line.

  3 Reduce the Max Send Speed and then try to resend the document.

Other suggestions

These suggestions are not listed by relevance, but they have been identified as possible reasons for fax failures.

  • The remote fax machine has your station ID, number, or Caller ID blocked for some reason.
  • A driver-initiated fax was sent to an MFP configured to forward faxes to a FAX-SERVER. Driver faxes are not not supported with this MFP configuration.
  • Delay send was temporarily activated on the MFP by accident.
  • Another job in the fax queue is preventing the MFP's fax-modem from dialing immediately. You will have to the wait or clear other fax jobs to send your fax.
  • Distinctive ring was incorrectly configured on the remote fax machine.
