maybe this may help its not for you model or the dll you mention,but it does say the error occurs because
"This is caused by a failed installation of the printer driver. It arises when you try to reinstall the printer driver".
To resolve this problem:
Disconnect the USB cable. Insert the installation disk. Click on the following option: View License Agreement, Web Links and other Useful Tools. Click on Uninstall Printer Software. Follow the on-screen instructions to complete the uninstallation. Restart the PC. Go to Windows Explorer. Click on the + (plus sign) next to (C:). Click on the + next to Windows. Click on the + next to System32. Click on the + next to Spool. Click on the + next toDrivers. Click on the + next to w32x86. Delete the contents of the w32x86 folder. Empty the recycle bin and restart the PC. Insert the installation disk and click on Install. When prompted to check that all cables are attached, connect the USB cable.
Maybe trying this will help?.This applies to windows xp.
I have searched the Lexmark datbase and cannot find anything about Sgss3UM.dll the closest thing i could find was what i posted above,it says it may be related and is not device specific so it may work it may not.
