Firmware Update Steps

Step 1: Check Device Firmware Level

Obtain the MFP's current device firmware level. You may use either Options 1 or 2 on ways to determine printer firmware code levels.

Option 1

Print the Menu Settings Page. Do this from the printer's operator panel:

StepAction
1Press the Menu button on the Operator Panel.
2Touch
next to Reports.
3Print the Menu Settings Page.
Note:
The printer should read ‘Printing Menu Settings Page’ and the menu settings page(s) should print out.
4Check the code level under Device Information section on the menu settings pages.

Option 2

Access the printer's Embedded Web Server (EWS). Before you begin, a functional network installation (wired or wireless not a local USB installation) is required for access to the web server of any Lexmark network printer.

Step Action
1 Determine the IP address of the print server within the printer/MFP.
2Launch your preferred web browser application (e.g., Firefox, Safari, Internet Explorer).
3In the address field after the http://, enter the printer's IP address (e.g., http://192.168.1.5 or http://169.254.1.42).
4Click on Reports.
5To check for the code level, click on Device Information.

Step 2: Identify Fix Firmware for your MFP

Contact Lexmark Technical Support to obtain the .P270, .P273, or .P283 software code.

Model Fix Firmware
X548.P270 or greater
X792.P283 or greater
X925.P273 or greater
X95x.P283 or greater

Step 3: DLEs and Special Firmware

Certain functions or applications may require special firmware.

WARNING! Make this information known to the call center agent and do not attempt to update the MFP firmware if the format of firmware number differs greatly from what is seen in the table just viewed.

Any MFP with any one of these following downloadable language emulators (DLE) may require special firmware versions:

• Bar Code • IPDS • PrintCryption • Forms • Prescribe • ImageQuick

Step 4: Need Help Updating Firmware?

After you have contacted Lexmark for this firmware, extract the .fls file to a known easy-to-find directory, and xref_HO3493_xref for an extensive list of the firmware update procedures.


NOTE:
Follow any of the update procedures.

Recommendation: The printer's web page has an Update Firmware feature that is easy to use.

Explanation

The modem fails to reset after a fax, which triggers the 900.00 error. The job queue will recover following a reset of the device; however, to prevent future crashes, please update your printer's firmware.

Still Need Help?

Please contact Lexmark Technical Support for additional assistance.
NOTE:
When calling for support, you will be asked for your machine/model type and serial number (SN).

Please call from near the printer or near a computer in case a technician on the phone requests that you perform a task on either one these devices.
