Fax error codes and recommendations

Overview

A fax error code may provide the necessary information to resolve a fax issue.

Where to begin

  1. Obtain the Transmission Log and the Fax Call Log, which will often display an additional fax error code that identifies the reason for a failed fax.

    See this article for information on how to view or print the fax call log, or see this article for information on how to enable fax logs.

    Note:  Many of these errors are associated with poor phone line conditions. Attenuation (signal loss) or excessive noise (interference) in the phone line are primary culprits for fax failures.

    Before you contact technical support, it is recommended that you contact your phone service provider to have the phone line tested. If available, connect a standard phone to the same fax line and perform your own preliminary quality test.

  2. Print your fax settings via Menus > Reports > Menu Settings Page.

    Note:  You may also view these settings from your printer's Embedded Web Server (EWS) under Reports > Device Settings > Analog Fax Settings. See this article to view steps to access printer's EWS.

  3. Further identify the fax problem.

Notes:

  • View the IP address on the printer control panel in the TCP/IP section under the Networks/Ports menu, or print a Network Setup page to locate the IP address under the TCP/IP heading.
