Recommended Actions
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:
| Step | Action |
| 1 | Press the Menu button on the Operator Panel. |
| 2 | Touch next to Reports. |
| 3 | Print the Menu Settings Page.
Note: The printer should read ‘Printing Menu Settings Page’ and the menu settings page(s) should print out. |
| 4 | Check 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. |
| 2 | Launch your preferred web browser application (e.g., Firefox, Safari, Internet Explorer). |
| 3 | In 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). |
| 4 | Click on Reports. |
| 5 | To 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 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.
