Explanation


Some security changes were implemented in the latest version of the Java code; consequently, this requires revising some property settings in the Scan Profile JAR file.

NOTE: Lexmark uses Java JAR files and the host computer needs the Java client installed in order to run the Scan Profile application.

 

Recommended solution


To resolve this issue, the printer’s firmware should be updated to the corresponding PE Release codes per model:

Printer Model

Firmware Fix (or greater)

X264 or X364 LL.BZ.P542
X46x LR.BS.P685
X54x LL.EL.P542
X65x LR.MN.P685
X73x LR.FL.P685
C74x, C79x, C925, C95x, X548, X74x, X79x, X92x, or X95x .P327
CS310, CS410, CS510
CX310, CX410, CX510
MS310, MS410, MS510, MS61x, MS61xe, MS810e, MS812e, or MS81x
MX310, MX410, MX511, MX511e, MX61xe, MX71x, or MX81x
.P340

NOTE: Please contact Lexmark Technical Support to obtain the firmware. Our Phone or Chat Support Agents can also guide you should you need assistance in doing the update.

 

IMPORTANT! This firmware code will not completely stop all warning messages. It will suppress some and provide explanations for others.

For instance,

  • Upon running the Scan Profile on the host computer for the first time, a warning message “Lexmark Scan Applet” will be shown.

    Required Action:
    You need to check the “Do not show again…” so as to install a Java Certificate from Lexmark. This allows the computer to trust this device and never show the message again.
     
  • Upon submitting a Scan Profile, another warning message will appear. It is caused by a security application that will not be changed.

    Required Action: You need to click “Continue”. This will open the communication to the printer that awaits for the scan to be started from the printer control panel.
     
  • Upon running the VNC Viewer on the host computer for the first time, a warning message “VncViewer” will display.

Still need help?


Please contact Lexmark Technical Support if you need 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 in case the technician on the phone asks you to perform a task involving the printer.
