Environment

This document is applicable to the following Lexmark Multifunction printer (MFP) models: MX310, MX410, MX510, MX61x, MX71x, MX81x, CX310, CX410, & CX510.

Solution

What you will see 
 

Calls are failing when you send a fax and the device displays an E970 error. The device may work properly for the first couple of calls after you restart it but then will fail until it has been restarted again.

 

Possible cause
 

It is possible that the devices are on a shared line.

 

Recommended solution
 

To resolve the issue and avoid experiencing the same error, access the printer’s Fax Settings and disable the following:

  • Enable Line Connected Detection
  • Enable Line In Wrong Jack Detection
  • Enable Extension In Use Support

You can change these settings using the printer’s Operator Panel Menu or by accessing the printer’s Embedded Web Server (EWS). To change the settings using the EWS, follow these steps:

  1. Open an Internet browser; e.g., Internet Explorer, Google Chrome, etc.
  2. Type the printer’s IP address in the browser’s address field.
  3. Click “Settings” on the left pane.
  4. Click “Fax settings” and then “Analog Fax Setup”.
  5. Uncheck the options as shown in the image below.

Make sure the options boxed in red are all unchecked.

IMPORTANT! Power cycle (restart) the device to reset the modem and the current line status.
