Support article for Lexmark MS821
This article explains how to perform printer firmware update through File Transfer Protocol (FTP).
Note: FTP update cannot be done with a USB cable connection. This procedure must be performed with the printer connected via an Ethernet cable to the network. It is not advisable to do this wirelessly (for wireless-capable devices) since a wireless connection is susceptible to data loss and interference. Data loss could cause damage to the printer during a firmware update.
Note: Firmware update is essential to optimize the performance of the printer. However, this procedure must only be performed when Lexmark Technical Support has recommended a firmware update. Recommendations are made by a technician if updating the printer firmware corrects a printer function or a printing anomaly.

Warning—Potential Damage: Do not update the firmware if you are unsure about the presence of special code or code that is specific to a Downloadable Language Emulator (DLE). For more information, contact Lexmark Technical Support.
Note: If you are using Windows Vista and above, please make sure to run the command prompt as Administrator.
Type the following command: ftp <printer IP address> and then press Enter.
Enter the Security Pin or hit Enter if no Security Pin is set up.
Note: Once logged in, you should be able to see the next window.
Type the following command:put <File Location> and then press Enter.
Note: You can type the word “put” first then drag the file toward the command prompt window; this shows you the exact location of the file.
If the UNC command (path to the location of the file) contains a space, make sure to enclose the UNC path with double quotes (“).
Note: This should send the firmware file over to the printer.
The printer displays a message that it is updating the firmware.
Warning—Potential Damage: Do not interrupt the firmware update. After completion, the printer should return to a Ready state.
Type bye and press Enter to close the FTP session.
