If you have any HP scanner installed on your computer and want to upgrade to a newer HP Scanjet 5300C, or 6300C scanner, you may need this update. The recommended procedure should be to: 1) Uninstall current scanner software. 2) Install new scanner software. 3) If you have problems with the new software and/or scanner, then run this update.
Choose the file you want to download to your system. With your mouse, click on the file. The file will decompress into a default folder c:\sj590, or any folder of your choice. Go to c:\sj590 (or the folder you chose). Double-click on the file you downloaded. Click "Unzip" on the window that appears, then "OK" twice. The software upgrade will install automatically.
