Then the error message goes away
******the solution*******
Pre Instructions:
If you have been trying without success I suggest you do the following before starting.
-Uninstall all versions of SX Virtual Link that you have installed. (use the uninstaller provided, or use appzapper http://www.appzapper.com/)
-Uninstall all versions of D-Link Shareport that you installed. (same methods)
-delete all installation files of the above as to prevent confusion or mistakes (+empty trash)
-Close all, and restart.
1.A In the System Preference in Mac, delete your printer.
1.B Restart.
2. Download and use Silex utility rather than the d-link re branded version. Much more stable.

2.B restart.
3. Start your printer first, open the utility and connect, print your document.
3. To go from printing a document to scanning a document, you must disconnect the link, turn off the printer, and start again. The utility does not work well with multifunction devices.
