Hi, and thank you for asking your question.
You may download the full installation disk (compressed as a ZIP file) for your Muratec MFX 2850 product, using the following link:
Save the ZIP file to your system first, when prompted, and then open up the saved file.
Click "Extract All" at the top to extract the contents of the ZIP file to a location of your choice.
Done extracting, go to the extracted location and open up the "Setup.exe" file listed, to start installation of the product driver accordingly. This should do it.
If you need more help, please use the Reply tab to continue our conversation.
