I tried to install my product's software for an Ethernet connection but cannot complete the installation in Windows or OS X. What should I do?

• Uninstall the printer software, then reinstall the software. Before reinstalling the software, check for the following:
  • Make sure your system meets the requirements.
  • Close any other programs, including screen savers and virus protection software, and install your product software again.
  • If you see an error message or your software does not install correctly in Windows, you may not have software installation privileges. Contact your System Administrator.
  • Make sure your product is turned on and the network cable is securely connected at both ends. If you still have problems installing software, disconnect the cable and carefully follow the instructions on the Start Here sheet.
